I believe that is even too burden as a qualification task, much of the libavfilter audio design has yet to be done. > A qualification task could be to add AVCodecContext get_buffer > functionality to audio decoders. As alternative to this, any video libavfilter task should be OK (e.g. port a filter from MPlayer/libmpcodecs or write a new one), note that vf_imlib.c is *not* a valid qualification task (see https://roundup.ffmpeg.org/issue302), this should help you to get confident with the FFmpeg/libavfilter API. I especially recommend: a deinterlace filter (check the code in libavcodec/imgconvert.c), a libfreetype wrapper (check as reference vhook/drawtext.c in ffmpeg-0.5). Ask here or on IRC if you have questions. Regards. _______________________________________________ FFmpeg-soc mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc
