Confusion on choosing a qualification task
Hello , I have seen the qualification tasks , but I am unable to decide on how to choose one as only the requirements of the task have been noted down . Where will I find the doc's ? The doc links accompanying the task only briefs about that particular codec/decoder/issue I have previously read the theory behind H.264 codec , but before I start going through the code I will need its documentation . I have checked out the ffmpeg code , long back and I had used the ffmpeg api's for compressing the video frames .My previous project required this to be simulated since the video capture card wasn't available at development time. and what is the next procedure send a mail to the devel-list stating the name of the task ? Could you please help me Greetings , Sathvik.

Actually, this isn't the ffmpeg-devel list; it's the ffmpeg-soc list. That's okay; it's useful to be on both. What do you want to do? Are you interested in a FFmpeg project for GSoC? Then you will need to do a qualification task. What qualification task are you thinking of doing (out of the ones that aren't claimed, and we have some more on the way)? We'll start from a task and then discuss what you need to do to complete it satisfactorily. Thanks for your interest in the FFmpeg GSoC program. -- -Mike Melanson
Hello Mike , I was going through the documentations on how to add a codec . I have following tasks in mind , could you give me your suggestions # 1 Apple RPZA encoder --> I don't understand why wasn't it checked in . can I know what will be my job ? #2 QuickTime Edit List Support I don't get the idea of edit list support . #3 PAF Playback System Task 3 seems to be more clearer to me that I will be adding a demuxer and video decoder . Could you give me your inputs . I don't want to end up choosing something I cannot finish in time. On Fri, Mar 21, 2008 at 1:20 AM, Mike Melanson <mike@multimedia.cx> wrote:

Hopefully, someone will be able to dig up the old list correspondence. If not, you can take the existing patch, make it work with the current SVN, send a next patch to the list, and we will then let you know what's wrong with it.
#2 QuickTime Edit List Support I don't get the idea of edit list support .
No one does. I implemented this for xine but I blocked it out of my mind. Download the QuickTime spec and find out what the elst and edts atoms look like. Modify the mov demuxer to parse them instead of skipping them.
#3 PAF Playback System
Task 3 seems to be more clearer to me that I will be adding a demuxer and video decoder . Could you give me your inputs . I don't want to end up choosing something I cannot finish in time.
Problem with task #3: I'm still finishing the description. I hope to have it done today. -- -Mike Melanson
Hi , I decided to work on the edit list support for quick time . I am using the quick time file format spec ( qtff.pdf ) , also the specs in multimedia.cx . The implementation code of the demuxer i guess is in mov.c ps: [You top-posted. Bad n00b. This is a warning.] I didn't get this . I was posting for 2nd time after I joined .

I told you in private already, several people on the list told you. You did not ask Google, which would have answered your question with the first hit... Diego
