Date: Sun, 12 Jan 2003 10:20:17 -0800 Okay, I'm still tired. I clicked send instead of save. Anyway, I chose this design because it allowed me to get a bookmark capability functioning quickly since I listen to 25+ hour audio books while I work out. I had originally not planned to support playlists and instead implement just an mp3 bookmark capability, but changed my after corresponding with Hardeep Sidhu, who suggested I just store the resume information. Once I looked into writing the resume information, I realized that it would be easier to just leverage the existing resume capability instead of attempting to write a whole bunch of code that duplicates existing functionality (i.e. start_resume()). Once I had done this, I found the resume needed to be set to "ask" or "yes" and considered modifying start_resume to take an additional parameter, but I wanted to get feedback from the rest of the group based on what I had already done before I start modifying existing code beyond what I had already done.

It was a little late :-). I have notes in the source explaining the design a bit. I basically took a lazy approach and leveraged the built in resume capability of Rockbox. To that end, I over write any existing resume information that is currently in memory and over write it with the stored information and then call the existing start_resume function (which explains why resume has to be set to "ask" or "yes". I wanted to get a functioning version up because I'm not sure how much time I'll be able to devote to this from this point on (pesky work) and I could us some help/suggestions to speed up the development process (gotta love open source). Below is further information on the bookmark capability. ------------------------------------------------------------------------ -- Writing a bookmark ------------------------------------------------------------------------ -- This bookmark capability takes the current resume information and writes it to a file whose name is based off of the currently playing file i.e. bookmarking /foo1/foo.mp3 creates the file /foo1/foo.bmf. This file contains the following line: resume_index*resume_offset*resume_seed*resume_first_index*queue_resume_i ndex*resume_file* ------------------------------------------------------------------------ -- Loading a bookmark ------------------------------------------------------------------------ -- When loaded, the bookmark_load function takes a bookmark file and reads the above line, one character at a time until it hits an asterisk (*). Once it does, this signals that this is the end of a field. As each field is successfully loaded, it overwrites the existing resume information that is stored in memory. Once all fields have been successfully loaded, bookmark_load calls tree.c:start_resume(). - Ben -----Original Message----- From: owner-rockbox_at_cool.haxx.se [mailto:owner-rockbox_at_cool.haxx.se] On Behalf Of Björn Stenberg Sent: Sunday, January 12, 2003 2:32 AM To: rockbox_at_cool.haxx.se Subject: Re: Book Marking Functionality Benjamin Metzler wrote: > I have created a bookmark functionality with the rockbox code. Please also describe the design you have chosen. We have discussed several ways of handling bookmarks. Which one did you choose, and why? -- BjörnReceived on 2003-01-12 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
