| 00:27:39 | Llorean | No idea. |
| 00:28:18 | Llorean | I think people have argued against it, but I honestly can't remember anything beyond "some buttons could have unexpected behaviour like fast forward" which doesn't seem much of a real problem / likelihood (I think people will realize holding a button will do whatever that button *does* until they insert the USB cable) |

| 00:38:21 | JdGordon| | I personally think a menu on connect is the best way to do it but noone will come to an agreement |

| 00:41:14 | gevaerts | The button to use is in usb.h |
| 00:41:30 | saratoga | what header do i need to use MEM_ALIGN |
| 00:41:34 | Llorean | JdGordon|: Well there still needs to be a decision for cases where a menu can't come up, or be used for whatever reason, so menuless behaviour is still good whether or not a menu will go in in the future. |
| 00:41:56 | saratoga | it shouldn't check for any particular button, just if (btn) |
| 00:42:01 | saratoga | no bitmask |
| 00:42:22 | JdGordon| | that has been one of the common arguments |

| 00:50:20 | saratoga | i just want to use mem_align in a codec |
| 00:50:31 | saratoga | and it randomly works or doesn't work in some files depending on the make -j setting |
| 00:53:01 | saratoga | huh __attribute__((aligned(16))) doesn't work either |

| 02:23:00 | saratoga | basically i want to be able to choose any of the options on the menu with or without boosting |
| 02:24:54 | JdGordon| | probably not very much... hang on |
| 02:27:29 | JdGordon| | just add an item to the MENUITEM_STRINGLIST() and check for it, then goto show_menu; |
| 02:30:50 | saratoga | JdGordon|: I have to do a "rb->set_option" if I want the yes/no menu right? |
| 02:31:19 | JdGordon| | sounds right |
| 02:31:32 | JdGordon| | umm, maybe not |
| 02:32:16 | JdGordon| | you could just do "toggle boost" and then a splash saying "Boost on/off" |
| 02:33:40 | saratoga | yes/no is probably better though, since eventually i want to have othe roptions |
| 02:34:09 | saratoga | in the opt_items structs, what does the second column mean? its usually -1 |
| 02:34:10 | JdGordon| | I cant remember if set_option only works with the global_setting settings or not |

| 02:40:52 | JdGordon| | pastebin |
| 02:40:56 | saratoga | where boost is the variable |

| 08:15:43 | saratoga | did you see the patch i put up before about USB charge mode? |
| 08:16:47 | saratoga | Buschel: alignment mostly helps if you do ldm or load doubles to aligned buffers, so if aligning something doesn't help theres probably no multiple loads going on |
| 08:17:01 | saratoga | that might mean theres a chance to further optimize accessing that buffer |
| 08:18:09 | Buschel | yes, seems like the access to qmf_window[] is the main optimization |

| 08:22:15 | saratoga | maybe it was aligned by chance |
| 08:28:14 | amiconn | saratoga: The USB power button should always be chosen so that the action its long-press will trigger is not confusing or dangerous |
| 08:28:36 | Llorean | amiconn: If it's "all buttons" then assuming any button has a safe action, it'll always be available to the user |
| 08:28:46 | Llorean | Since "safe" can vary from screen to screen, or even based on the opinion of the user. |
| 08:29:07 | Llorean | I consider context menu generally safer than quickscreen, for example |
| 08:29:10 | Llorean | But not everyone agrees. |
| 08:29:11 | amiconn | The commit message for 7674 says why USBPOWER_BTN_IGNORE was added. |
| 08:30:41 | amiconn | The original ones (MODE for ondios, F1 for recorder fm/v2) are the menu buttons on their respective targets |
| 08:31:00 | * | Llorean doesn't see how "all buttons" introduces a new danger. |
| 08:31:17 | Llorean | Is the theory that users will assume that not a single button on the player will do anything other than allow USB mode when held? |
| 08:31:29 | amiconn | It does - for the very same reason why USBPOWER_BTN_IGNORE was introduced |
| 08:31:52 | Llorean | Could you explain that simply? |
| 08:31:55 | amiconn | That would cause devices with flashed rockbox to *always* enter usb power mode on startup |
| 08:32:36 | Llorean | So boot and then insert the cable? |
| 08:32:40 | amiconn | I.e. the button which is used to power up the device *must* be ignored |
| 08:33:01 | amiconn | What if you can't boot without power from USB? |
| 08:33:02 | Llorean | Or put in a special condition that the BTN_IGNORE button is ignore until boot "completes" safely |
| 08:33:24 | | Quit BHSPitMonkey (Remote host closed the connection) |
| 08:33:28 | amiconn | Completion is too quick for this |
| 08:33:31 | Llorean | If you can't boot without power from USB, isn't going into USB charging mode acceptable? You could then replug if you'd like UMS much like you have to if you're charging anyway and decide you want UMS access. |
| 08:33:47 | Llorean | The boot is too fast to give the user time to let go of the button? |
| 08:34:14 | amiconn | The Ondio can be used from USB power with no batteries inserted. If any button enters USB power mode, you would always end up there, and be unable to enter mass storage mode |
| 08:34:48 | Llorean | So the boot is too fast for a user to be able to let go of the button before it completes? |
| 08:35:17 | | Join kish_ [0] (~o2@unaffiliated/spice) |
| 08:35:19 | amiconn | Yes, because you need to hold it for a short while, until you can be sure that it boots |
| 08:35:34 | amiconn | Otherwise USBPOWER_BTN_IGNORE wouldn't have been introduced |
| 08:36:04 | Llorean | Things are introduced that aren't strictly speaking necessary, so I wasn't willing to make that assumption |
| 08:36:45 | Llorean | Even then, why not just ignore all "power" buttons? Since it's nonsense to hold down the button that shuts down the player to try to insert USB. If you're even a little slow you don't get anything |
| 08:37:27 | amiconn | Yes, that's what is necessary. |

| 08:37:55 | Llorean | Or allow a button on the player to disconnect USB (if HID is not enabled) and a menu entry to enter MSC if charging from USB (these might be nice anyway) |
| 08:38:26 | Llorean | I'd really like a button to drop out of MSC, honestly, for my car where trying to hold down things is impractical, or where the player is waked by USB power and then enters MSC and replugging the cable is potentially unsafe while driving. |
| 08:38:59 | | Join esperegu [0] (~quassel@145.116.15.244) |
| 08:39:18 | amiconn | Yes, that might be useful. It also seems that some users would prefern an option what to do on usb insert instead of that button-hold mechanism |
| 08:39:56 | Llorean | My ideal would be an option to decide if the default is connect or charge, every button (or nearly every button) causing it to perform the other action, and a button that gets me out of MSC if I'm accidentally in it without having to replug. |
| 08:40:32 | Llorean | I think a menu would slow things down, and you'd still want it to timeout to one or the other (and which it would timeout to being probably user selected) anyway |
| 08:40:34 | amiconn | Something that resemples "Stop" would be the proper button for this I think |
| 08:40:38 | Llorean | Probably, yes. |
| 08:41:12 | amiconn | I'm not talking about a menu at insert (which might be impossible in the current screen) |
| 08:41:58 | Llorean | Ah, well some people want a menu at insert. Not me, though. |
| 08:42:21 | Llorean | I want a menu where I can decide what insert will do by default, then if I hold a button it does the opposite of what I've chosen. |
| 08:42:47 | Llorean | Since I'd much prefer the default on my in-car player to be charge, while the default on my Beast to be MSC |

| 12:17:40 | * | TheSeven has a question about "const" |
| 12:19:02 | TheSeven | if i have a register that needs to be set to an address, and the data at that address won't be affected by the address being written to that register, how do i declare that? |
| 12:19:42 | TheSeven | #define DMAC0C0SRCADDR (*((volatile void**)(0x38200100))) will complain that the const qualifier (on the argument passed to the function that writes the address to that register) is discarded |
| 12:20:03 | TheSeven | #define DMAC0C0SRCADDR (*((volatile const void**)(0x38200100))) seems to tell the compiler that the register would be read-only |
| 12:20:16 | TheSeven | is there even a way to do that? |
| 12:24:20 | TheSeven | come on, there must have been similar cases before... |
| 12:24:36 | | Join Dreamxtreme [0] (~Dre@92.30.31.119) |
| 12:24:39 | TheSeven | or didn't we bother about register types at all and just casted everything to an int when writing to a reg? |
| 12:25:16 | n1s | TheSeven: i'm not sure i understand what you mean but i think you want volatile void* const* if i remember the syntax correctly |
| 12:26:21 | n1s | ie pointer to a constant pointer to volatile data |
| 12:27:57 | Torne | isn't it, in fact, void * volatile const * |
| 12:28:01 | Torne | or something similarly insane |
| 12:28:09 | Torne | since it's the pointer which is volatile, not the target |
| 12:28:17 | n1s | oh |
| 12:28:27 | n1s | volatile const is nice :) |
| 12:29:24 | Torne | personally i vote for casting it to int |
| 12:29:43 | Torne | and having the registers all be the same type |
| 12:31:34 | TheSeven | what i actually want is a pointer to a volatile pointer to constant data |
| 12:32:16 | n1s | const void* volatile* foo |
| 12:32:31 | * | n1s recommends cdecl |
| 12:33:01 | n1s | but basically just write it backwards |
| 12:34:08 | TheSeven | what does *((volatile const void**)whatever) actually do then? |
| 12:34:28 | TheSeven | or even &(*((volatile const void**)(whatever))) |
| 12:34:50 | n1s | http://www.cdecl.org/ |
| 12:35:47 | n1s | volatile const void** is "pointer to pointer to volatile const void" so you cast whatever to that and dereference the first pointer so you get a "pointer to volatile const" |

| 12:36:26 | TheSeven | funny, eh? :D |
| 12:37:03 | n1s | &(*(...)) seems pointless |

| 12:42:54 | TheSeven | n1s: it isn't if the * is part of a define, but the & is outside |
| 12:43:07 | TheSeven | this is basically DMAC0C0DESTADDR = &LCDWDATA; |
| 12:44:01 | TheSeven | if "cast x into pointer to volatile pointer to const void" is what i want, that would be "(const void * volatile *)x" |
| 12:45:02 | n1s | yes |
| 12:45:20 | TheSeven | now look at http://svn.rockbox.org/viewvc.cgi/trunk/firmware/export/s5l8700.h?view=markup |
| 12:45:41 | TheSeven | doesn't this mean that REG32_PTR_T should actually be "uint32_t volatile*" |
| 12:46:15 | Torne | no, because the relative order of a (normal) typename and const/volatile is meaningless |
| 12:46:24 | Torne | "volatile int" and "int volatile" are the same type |
| 12:46:43 | TheSeven | ok, but as soon as this is void* instead of uint32_t, it isn't? |
| 12:46:46 | Torne | it gets complicated if the typename is actually a typedef for a composite |
| 12:46:50 | Torne | Yeah |
| 12:46:57 | Torne | this is just one of those things in C |
| 12:47:14 | TheSeven | urgh |
| 12:47:31 | Torne | it accepts both, and people tend to write volatile int, but as soon as the type isn't a primitive it may matter which you write |
| 12:49:38 | Torne | it would be much more sensible if the language required qualifiers to follow types always, because then the read-right-to-left rule would mostly be sufficient :) |
| 12:49:45 | Torne | typedefs can still fuck it up if you try hard enough |

| 12:53:59 | Torne | the cases like this are too rare |
| 12:54:29 | *** | Saving seen data "./dancer.seen" |
| 12:55:02 | TheSeven | now why does (*((void* volatile*)(0x38200104))) = &(*((uint32_t volatile*)(0x38300040))); say "assignment discards qualifiers from pointer target type"? |
| 12:55:48 | TheSeven | the same happens for void* test = &(*((uint32_t volatile*)(0x38300040))); |
| 12:56:21 | TheSeven | does it think the DMA controller might not know about its volatility? |
| 12:56:29 | Torne | because dereferencing it and then taking its address again eliminates the volatile |
| 12:56:34 | Torne | i think |
| 12:56:47 | TheSeven | any way to suppress that? (it's intentional) |
| 12:57:00 | n1s | more casting :) |
| 12:57:04 | Torne | no. in fact, i think that expressoin might even be required to have side effects |
| 12:57:23 | Torne | *((uint32_t volatile*)(address)) is supposed to issue a read |
| 12:57:26 | Torne | because of the volatile |
| 12:57:30 | TheSeven | i still want writes to *((uint32_t volatile*)(0x38300040)) (which is used as a define in there) to be volatile |
| 12:57:40 | Torne | I don't think you can do it |
| 12:58:05 | n1s | using an intermediate var to store the adress would work, no? |
| 12:58:16 | Torne | only with *another* cast |
| 12:58:47 | TheSeven | is there some way to get to the address inside that define without triggering that warning or issuing a read to it? |
| 12:58:51 | | Quit user890104 () |
| 12:58:54 | Torne | anyway, i think you'll find the type of your RHS there is uint32_t * |
| 12:58:57 | TheSeven | (even if it means some more casts :) ) |
| 12:59:09 | Torne | and the type of the LHS is void * volatile |
| 12:59:16 | Torne | so it is indeed discarding qualifiers |
| 12:59:39 | TheSeven | what's bad about (void* volatile) = (uint32_t*)? |
| 12:59:50 | Torne | hm |
| 13:00 |
| 13:00:06 | TheSeven | doesn't this just mean that the LHS must be written to immediately? |
| 13:00:16 | TheSeven | the type cast to void shouldn't matter IIUC |
| 13:00:16 | * | Torne repeats his earlier suggestion that you cast the address to an int |
| 13:00:19 | Torne | :) |
| 13:00:48 | TheSeven | let's say we have #define LCDWDATA (*((uint32_t volatile*)(0x38300040))) |
| 13:01:09 | TheSeven | int whatever = (int)&LCDWDATA; won't help, right? |
| 13:01:21 | Torne | why not> |
| 13:01:27 | TheSeven | so there's nothing I can do outside of that define to get at its address? |
| 13:01:47 | TheSeven | IIUC the "&LCDWDATA" part is sufficient to trigger the warning |
| 13:01:58 | Torne | not on its own |
| 13:02:06 | Torne | it's an assignment warning |
| 13:02:12 | * | TheSeven has misunderstood something then :) |
| 13:02:15 | Torne | an expression can't generate that without an assignment in it |
| 13:02:39 | TheSeven | so basically DMAC0C0DESTADDR = (void*)((int)LCDWDATA); might work? |
| 13:03:04 | Torne | (not without an &) |
| 13:03:07 | Torne | (and who knows) |
| 13:03:19 | * | Torne suggests just defining the LHS register as volatile int * |
| 13:03:30 | Torne | and abandoning any pretence of type safety |
| 13:03:52 | Torne | addresses are uint32_t. it doesn't need to actually be a pointer :) |
| 13:04:10 | amiconn | TheSeven: Why care about register types? So far we didn't |
| 13:04:42 | Torne | indeed |
| 13:04:43 | TheSeven | because I personally don't like casting addresses to integers all the time for DMA |
| 13:04:53 | amiconn | Hmm? |
| 13:04:55 | TheSeven | well, pointers :) |
| 13:05:16 | TheSeven | the code would be full of REG = (uint32_t)thing; |
| 13:05:17 | Torne | actual type safety is impossible in C anyway, just give up :) |
| 13:06:04 | amiconn | Why? The cast is implicit anyway |
| 13:06:22 | TheSeven | REG = thing; triggers a warning |
| 13:07:19 | amiconn | Look at mcf5249.h, pp5020.h etc - registers are defined as (*(volatile unsigned long*)(0xADDRESS)) (or short resp. char) all over |

| 14:43:46 | saratoga_ | n1s: ive hoped someone would look at fft8 on cf for a while |
| 14:44:09 | saratoga_ | it accounts for a large fraction of the entire fft |
| 14:44:23 | saratoga_ | and its very short |
| 14:44:35 | n1s | saratoga_: yes, i'm taking a look now, starting with fft4 now, gcc4.4 produces significantly worse code for this than 3.4 :/ |
| 14:45:01 | saratoga_ | yeah it screwed up on arm too |
| 14:45:11 | | Quit Zambezi (Remote host closed the connection) |
| 14:45:46 | saratoga_ | iirc fft4 becomes a few loads adds and stores in fft8 and gcc has no idea how to do it |
| 14:47:56 | saratoga_ | is there any advantage to sequential loads to iram on cf, |
| 14:48:04 | saratoga_ | ? |
| 14:48:30 | n1s | not much, should be slightly faster |
| 14:49:24 | saratoga_ | i want to special case the 2048/512 fft case for targets with lots of iram or only dram |
| 14:49:44 | saratoga_ | rearrange the trig values to be sequential |
| 14:50:19 | saratoga_ | probably help a lot on arm11, no idea if its useful on cf targets with 128k iram |

| 14:55:35 | n1s | hmm, in fact load multiple should save cpu cycles when done from iram too, according to the cpu user manual |
| 14:55:59 | n1s | movem takes 1+n cycles while regular loads take 2 cycles |
| 14:56:18 | saratoga_ | same as arm7 then |
| 14:57:03 | saratoga_ | the current mdct is extremely clever about trig values thanks to stripwx, savesa ton of memory |
| 14:57:18 | saratoga_ | but the access patterns are a bit weird |
| 14:57:18 | n1s | saratoga: and even if not using movem, sequential loads usually mean autoinc adressing modes can be used which is faster than constant offsetts |
| 15:00 |
| 15:00:02 | saratoga_ | most codecs only use the 2048 block size 95 percent of the time, so we could halve the size of the trig tables, the add a separate table for the common case of the 2048 transform |
| 15:00:20 | saratoga_ | then sort it for sequential acess |
| 15:01:50 | n1s | that would probably help cf a bit if it could be in iram, but to make full use of sequential accesses we need to write asm... |

| 19:03:44 | pamaury | some it could be some sort of SHA-128 but I tried with zero key on some random program and it does not seem to be plain SHA-128 |
| 19:08:48 | bertrik | too bad, nice try anyway |
| 19:09:24 | pamaury | I currently trying to see if the executable section has exactly the same size as the binary. I alrzady noted that elftosb2 strips some part of the elf header |

| 19:09:58 | pamaury | but it could also add some hashing at regular positions, which would make it even harder to understand to algorithm :) |
| 19:10:38 | | Join DerPapst [0] (~Alexander@p5DE5AD09.dip.t-dialin.net) |
| 19:10:55 | bertrik | so you've already actually added something to a .sb with elftosb? |
| 19:11:13 | bertrik | I tried it with some chumby binaries |
| 19:12:43 | pamaury | I just built a dummy executable, then add it to the command file using load and indeed, it adds the binary |
| 19:13:09 | pamaury | when there is no encryption, it just creates a ____ section with the content but with part of elf header stripped. |
| 19:13:11 | bertrik | Just some ideas: make time() always return the same value with some preload magic, stub /dev/urandom |
| 19:14:40 | pamaury | I also decided that it was way to difficult to reverse engineer elftosb2, it's written in C++ and even though there lots of strings out there, it would probably be a nightmare |
| 19:14:44 | pamaury | *too |
| 19:14:45 | bertrik | And with "zero-key" encryption the binary is still undecryptable? |
| 19:14:50 | pamaury | yes |
| 19:15:11 | pamaury | but I still have lots of ideas before giving up |
| 19:15:53 | bertrik | Unless sandisk used some kind of default key, I think it's nearly impossible to make it accept a custom image. The crypto seems solid. |
| 19:16:55 | * | TheSeven guesses that D1671/D1759 might be part of the chip number of the nano3g/nano4g PMU. Any ideas what this thing could be? |
| 19:17:02 | pamaury | well, sha-128 is quite solid indeed :( But we have to make sure first that they didn't use the default key |
| 19:17:45 | alexbobP | bertrik: sandisk uses firmware signing? |
| 19:17:52 | alexbobP | on what device? |
| 19:18:07 | bertrik | alexbobP, I think so, not completely sure, on the fuze+ |

| 19:31:47 | n1s | amiconn: not in my experience |
| 19:31:51 | amiconn | Only indexed addressing is slower |
| 19:32:15 | amiconn | n1s: They all take two cycles for 32 bit, 3 cycles for 16 bit and 8 bit |
| 19:32:23 | n1s | what i've seen si that constant offsetts are slower |
| 19:32:41 | n1s | (i'd guess because they make the instructions longer) |

| 19:33:15 | n1s | same with using 32 bit immediate values |
| 19:33:28 | amiconn | Here we're talking 16 bit offsets though |
| 19:34:03 | amiconn | Iirc the pipeline is able to fetch 32 bits per cycle, so even back-to-back loads with 16 bit offsets shouldn't starve the pipeline |
| 19:34:39 | amiconn | You may see aliasing effects caused by the icache though. These are tricky |
| 19:34:54 | n1s | right, not sure if i've tested with move.l but emac paralell loading was measurably faster with sequential access and postinc rather that offsetts when i made a test for Buschel on mpc |
| 19:35:14 | n1s | those becone 48 bit instrs when using offsetts thogh |
| 19:35:20 | amiconn | Well, emac parallel load is of course faster |
| 19:35:30 | eWill | How many revisions back are on svn? |
| 19:35:49 | n1s | i mean that emac parallell load with postinc is faster than emac paralell load with offsett |
| 19:35:55 | amiconn | And instructions using two extension words will starve if issued back-to-back |
| 19:35:59 | gevaerts | eWill: back to r1 |
| 19:36:21 | n1s | amiconn: ok, so that is maybe only true for emac paralell loads then |
| 19:36:47 | amiconn | It only is if you're also issuing them back-to-back |
| 19:37:24 | n1s | (difference in that mpc filter loop was 0.9MHz with the dct reordered so that the paralell loads were sequential) |
| 19:37:29 | amiconn | Actually even then it shouldn't, because emac with parallel load needs two cycles anyway |
| 19:37:43 | eWill | wow cool. I've got to do the "find a good revision −− then go half way between that an the bad one −− then go half way between that and the bad one...." thing. What did you call that again? |
| 19:38:04 | n1s | eWill: bisection |
| 19:38:22 | amiconn | That may be simple aliasing. Reordering functions will change speed, often by several percent, in an unpredictable way. Slower or faster... |
| 19:39:00 | amiconn | (unless the code involved is in iram, of course) |
| 19:40:09 | n1s | i know, but that loop is in iram (as it's by far the hottest in the codec AFAIU) |
| 19:41:57 | amiconn | Make sure it actually is... when specifying both 'inline' and ICODE_ATTR, and the parent function is not in iram, the result may be different from what's intended |
| 19:42:23 | amiconn | It should be obvious, but nevertheless I've seen cases of that in rockbox |
| 19:43:02 | n1s | the one in musepack is a real asm function so it will never be inlined |
| 19:43:25 | CIA-7 | New commit by Buschel (r28641): Fix typo in comment. |
| 19:43:32 | n1s | btw i wonder why gcc doesn't warn if a function is inlined so it ends up in another section when you explicitley specify one |

| 20:51:44 | pixelma | you need to be a bit more descriptive ;) |
| 20:53:04 | eWill | I have to do some bisecting. Can I just make a copy of my RB development dir, and do it all in there? I'm trying, but "svn status" result is −−−− svn: warning: '.' is not a working copy |

| 20:53:56 | Nerdy3_14159265 | I was outside one day so I cranked the brightness on the Fuze, ever since when it starts it shows the rockbox logo then goes to a black screen and won't display anything |

| 20:56:46 | Nerdy3_14159265 | pixelma: It shouldn't be that it looped around because I played on it for a bit before the screen started just going to black, also I have no idea how to reset the settings without being able to see the screen and I have no cord atm to hook it to my pc |
| 20:59:06 | pixelma | some players let you reset settings during boot by holding a specific button. I'm not sure if this is implemented on the Fuze and which button it would be if it is, you could search around in our manual |

| 22:18:33 | bertrik | pixelma, I'm trying to figure out if the full range is perhaps possible by configuring some other part of the display. There is a note in the ds that says that under some circumstances the range is less. If that's not possible, I'm inclined to just reduce the range to 0-127 to avoid the wrap at 128 |
| 22:23:14 | bertrik | ranmachan, do you see the same effect w.r.t. contrast on the c200v2? |
| 22:24:14 | pixelma | I'd be fine with 128 |

| 22:30:08 | eWill | OK I've found the commit that broke a function for me (perhaps it's a "fix"?). The way it used to work on my e200v1: Location: WPS > Context Menu > Playlist Menu > Playlist > View Current Playlist. Function: Press Play/Pause button ("up" button) returned you to WPS. Since r28139 or r28140 (same author/file) this button now does nothing. Anyone care to take a look? http://svn.rockbo |

| 22:50:47 | saratoga | that Goodbye track plays for a second for me, then crashes |

| 22:51:06 | saratoga | the bitrate is 176k which isn't valid for atrac3 afaik |
| 22:51:09 | saratoga | so i don't know what it is |
| 22:51:09 | gevaerts | saratoga: that's somehow appropriate in a twisted way :) |
| 22:51:17 | merbanan | so it's not enough for me to have written a ffmpeg decoder for it ? |
| 22:51:18 | saratoga | ha |
| 22:51:27 | merbanan | I should write a rockbox version also |
| 22:51:40 | saratoga | write an atrac3plus decoder and i'll port that |

| 22:58:38 | saratoga | merbanan: awesome |
