This had a side-effect of leaving the field set to 0 when packet demuxing is carried out from another demuxer using avpriv functions, which could lead to demux failure. Hardcoded max_packet_size inside avpriv_mpegts_parse_open to 2048000 to avoid this. Value chosen to be 10x that of default value to accommodate large payloads. --- libavformat/mpegts.c | 1 + 1 file changed, 1 insertion(+) diff --git a/libavformat/mpegts.c b/libavformat/mpegts.c index da15223b8a..e23f596490 100644 --- a/libavformat/mpegts.c +++ b/libavformat/mpegts.c @@ -3377,6 +3377,7 @@ MpegTSContext *avpriv_mpegts_parse_open(AVFormatContext *s) return NULL; /* no stream case, currently used by RTP */ ts->raw_packet_size = TS_PACKET_SIZE; + ts->max_packet_size = 2048000; ts->stream = s; ts->auto_guess = 1; -- 2.34.1 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
