[FFmpeg-devel] [PATCH v2] avformat/oggdec: Add page CRC verification

2020-04-28 Thread Mattias Wadman
Fixes seek issue with ogg files that have segment data that happens to be encoded as a "OggS" page syncword. Very unlikely but seems to happen. Have been observed to happen with ffmpeg+libvorbis and oggenc encoding to 441khz stereo at 160kbps. --- libavformat/oggdec.c | 136 ++
