So mail is my preferred channel of communication. As already mentioned, you're welcome to work on the decoder aka your qualification task. And I think the deadline tomorrow does not hurt if you've met the OPW requirements already - which would be to the best of my knowledge to have submitted a formal application to OPW. > On Mon, Oct 20, 2014 at 7:25 AM, Thilo Borgmann > wrote: > >> Am 20.10.14 13:00, schrieb Michael Niedermayer: >>> On Mon, Oct 20, 2014 at 06:32:59AM -0400, Ngassa Finjap wrote: Hi, On Mon, Oct 20, 2014 at 6:20 AM, Michael Niedermayer wrote: > I see this has somewhat been awnsered on IRC > maybe thilo can elabrate on this, though I do not think its possible > to write such decoder in the remaining time before Wednesday unless > one knows what to do already and is quick. > I did a git grep and found ffmpeg/libavcodec/alsdec.c.

I think this is correct.

Hello, I was of the impression that even though the time for submitting patches is running out, any propective OPW applicant could still continue working on her tasks even after the application period is over right up to the selections are announced for the OPW?

Well, she can still do that, just not within the OPW program (since time is obviously running out). I believe most here would agree with helping new contributors even outside of programs like OPW or GSoC. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel

[FFmpeg-devel] Help with writing an RMS-LMS decoder
Hello, I am Ngassa Amalia (amalia on irc), an student interested in contributin to the ffmpeg project unde the OPW program.I have already created an account on githug(@Ngassa) and compiled ffmpeg from source. I have been asked to write an RMS-LMS decoder before Wednesday and I don't have a faint idea how to go about it. Please can anyone give me tips on how to go about this qualification task ? I am really flying blind here :( Cheers Ngassa Amalia ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
