My Personal Notes

TODO:

  • AA Fonts (someone has a patch on FS#8961)
    • Understand the Rockbox font rendering, then
    • Implement a new nbpp font format, after that
    • Implement font translucency.
  • OF UI simulator
    • A plugin for simulating other OF's UI is good to have.
  • GBK encoding
    • Understand fully GBK and GB18030, then
    • Update GB2312 encoding to GBK or GB18030.
  • Runtime
  • Scroll wheel click problem
    • Understand the scroll wheel detection for iPods, then
    • Ignore the scroll wheel while one of the four directional buttons are depressed.
  • Languages
    • Draw a flag for each language
    • Use native language names
  • Test ATA problem / hack on iPod 5.5g 80GB
    • Turn off the hack, then
    • Turn on database auto refresh, then
    • Turn on directory cache, then
    • Turn on resume at startup.
    • Notice lack of UI responsiveness / audio skipping
    • Note: This should be easily observed on 60GB and 80 GB iPod Videos.
    • Note 2: 5.5G iPod Video exports 2048-byte sectors over USB, although the drive is 512-byte sectors (30GB) or 1024-byte sectors (80GB).
  • Add option for FAT 16 support in tools/configure.
  • Help remove pluginlib by moving all button definitions to the respective apps.
  • Ipodpatcher --format and --convert options
    • Enhance --format to support 2048-byte sectors.
    • Test out the --convert option.
  • Database
    • Maybe we can avoid the reboot after initializing it.
    • Sometimes songs don't show up in the database.
    • Currently, the database says "xxx found". We should improve it to make it say "xxx files (zzz music files) and yyy directories found".
  • Music file buffering
    • Implement a more generic buffering, more like the page cache algorithm.
    • Currently, the files are buffered and then forgotten after they've been played.
    • Keep the code simple, otherwise it will be hard to get accepted.
  • Visual feedback for fade-out/fade-in
    • Llorean suggested using a blinking icon to show that playback is fading in or fading out.
      • The blink would be implemented as alternating icons.
      • I think fade in should blink the play icon and fade out should blink the pause icon, but this would be up to the WPS designer.
      • We just have to provide the mechanism, and the WPS designer sets the policy.
    • There is another method, that is to use a special animated icon to show the fade in or fade out status. But this is more complicated than Llorean's solution.
  • USB stack
    • Sometimes plugging in a USB cable will make RB go into UMS mode, sometimes it doesn't.
  • Bubbles plugin
    • Optimize the code. Investigate the possibility of using bubble paths instead of calculating every single move.
    • Fix the speed issue. Currently bubbles runs at different speeds, depending on the CPU speed. This is clearly wrong.
  • Problems with mkfs.vfat on the iPod 5.5g
    • Find the people who had problems with mkfs.vfat and ask them to try again.
    • Once done, deprecate mformat.
  • Ask ex-Ingenic contact
    • Documentation
    • Hardware info
  • Fix source tree structure
    • Makefile sometimes don't pick up changes.
    • Target builds are outside the tree while utilities are inside the tree.

DOing:

  • Help message display for plugins (FS#9232)
    • Use the one from solitaire.
    • Take it out and generalize it.
  • PATH (FS#9112)
    • Automatically append the cross compiler's path when compiling / configuring.
    • Currently there are two choices: $HOME/.config/rockbox.org/somefile or /tools/somefile
    • The current implementation stores the cross compiler prefix in ~/.config/rockbox.org/RockboxCompilerPrefix
    • The affected files are:
      • tools/rockboxdev.sh
      • tools/configure, along with the generated Makefile
  • Remove Repeat:Shuffle optionMake Shuffle:Yes and Repeat:All behave the same as Repeat:Shuffle (FS#9456)
    • Always reshuffle when Shuffle:Yes and Repeat:All
  • WenQuanYi Fonts (FS#9059) & (FS#9060)
    • Get markun to review the WenQuanYi font submissions.
  • Database hang when no music file found (FS#9093).
    • The database doesn't actually hang, the ready bit just didn't get set.
    • A simple patch has been uploaded. It basically allows the creation of an empty tagcache.
  • Remove pluginlib actions from bubbles plugin (FS#10194)
    • A patch has been uploaded.

Done

  • Maze plugin (FS#9184 & FS#9191)
    • This can be fixed by using the same data structure for the maze both in the stack and the main struct.
    • Clean up the code before submitting.
  • Move "Playback Settings" out of "General Settings" (FS#9472)
  • Menu system for plugins
    • Fix bubbles to use the menu system. The code has been fixed by someone else.

NODO

  • Use "/" instead of "Files" for root directory (FS#9461)
    • "Files" is a better way, because it integrates better with the main menu.
  • Reorganize Playback Settings menu (FS#9473)

Ideas

  • Big-icon lists for the menu
    • Llorean is basically opposed to this
    • scorche wants the objections to be addressed
    • Objections:
      • binsize
      • code overhead
      • code complexity
      • blind friendliness
      • functional benefits
      • maintenance nightmare
      • porting nightmare
      • theme change: require reboots?
      • ui change: require reboots?
      • theme compatibility

Notes:

  • Update the WenQuanYi fonts regularly. The BDF format is preferred.
  • Vector fonts are not in because of the processing overhead.
  • The fonts are drawn differently for each LCD type (1bit, 2bit, 16bit).
  • Remember to always check the output of convbdf.
  • The 2 MB limitation of FlySpray is only for single attachments.
  • The default UI will not be themable due to performance considerations.
  • To test the runtime against the OF,
    • Use the exact same set of music files.
    • Use a playlist (about 45-60 min), set to repeat, don't shuffle.
    • Reset the Rockbox settings to default.
    • Turn of accessory power: Settings -> General Settings -> System -> Accessory Power Supply.
    • Charge the battery to full using the bootloader USB mode, then restart Rockbox before starting. This is because "there is a higher power consumption that we do not understand right now" said Buschel, if we just charge inside Rockbox and run the battery test from there.
  • Rockbox doesn't support malloc, so after initializing the database, we need to reboot.
  • Plugins are compiled according to supported features of each DAP.
    • There is a SOURCES file in each plugin directory that controls which file gets compiled and which are not.
    • Therefore large #ifdef blocks inside plugins should be removed.
  • Plugin bitmaps are converted from bitmaps inside apps/plugins/bitmaps/ at build time into arrays inside C files. The header files are generated in pluginbitmaps/.
  • To enable logf(), define LOGF_ENABLE before including logf.h, and enable logf via the configure script.

My Personal Quotes

  • gevaerts: wpyh: if you put your rockbox dev tools in a directory designed for temporary files, we seriously have to doubt your commitment to the project wink
  • JdGordon: please accept this gift certificate for 300 free downloads from rockbox.org for causing such grief
  • Llorean: But I'm a cynic.
