[FFmpeg-devel] [rfc] tasks for new ffmpeg developers

people new to the project join #ffmpeg-devel and ask us for help on how to start contributing to ffmpeg. usually none of us have any cohesive answers. mostly suggestions are to review bugs or patches or code. nothing really concise or organized. i've reviewed a few bugs and think these may be

[FFmpeg-devel] [PATCH v2 2/2] avformat/hls: Add subtitle support

Each subtile segment is a WebVTT file and needs to be demuxed separately. These segments also contain a header to synchronize their timing with the MPEG TS stream so those timestamps are requested from the WebVTT demuxer through an AVOption. Signed-off-by: Franklin Phillips

[FFmpeg-devel] [PATCH v2 1/2] avformat/webvttdec: Add support for HLS WebVTT MPEG timestamp map

WebVTT subtitle files in HLS streams contain a header to synchronize the subtitles with the MPEG TS timestamps of the HLS stream. Add an AVOption to prefer MPEG TS style timestamps generated according to the mapping header, if available. Signed-off-by: Franklin Phillips

Re: [FFmpeg-devel] [PATCH 2/2] avformat/hls: Add subtitle support

Sorry for the test failure, I didn't realise there were tests for HLS demuxer because the tests don't have HLS in their names. I am sending new patches which don't break the tests. ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org

This adds "-profile[:v] profile_name"-style option IOW. "constrained," "baseline," "main" and "high" will work well on Raspbian Jessie / RasPi3B. The others aren't checked due to unsupported. --- libavcodec/omx.c | 91 1 file changed,

[FFmpeg-devel] How to set avcodec_open2 to set ((MpegEncContext *)(avctx->priv_data))->fixed_qscale = 1?

Hi , I'm trying to push a stream to a server with ffmpeg. I debugged the ffmpeg code, and found that when avcode_open2 returned, the ((MpegEncContext *)(avctx->priv_data))->fixed_qscale = 1. That to say, when video stream was handled, certain offset of avctx->priv_data pointer (just
