avformat/dashdec: The segments in dash file doesn't read completely when segment's size and duration is very small. If the segment is very small, avformat_find_stream_info will read all audio/video data in this segment. cur->is_restart_needed is set to 0 later in dash_read_packet, and no chance to be set to 1 again in the read_data function. Reproduction: ffmpeg -f lavfi -i mandelbrot -f lavfi -i anullsrc -c:v vp8 \ -g 5 -r 5 -c:a libopus -use_template 0 -seg_duration 1 \ -t 15 -y test_720.mpd ffprobe -show_packets test_720.mpd > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=f606872ed0e2224c6809870c2116273f768a80b0 --- libavformat/dashdec.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavformat/dashdec.c b/libavformat/dashdec.c index 555e21bf69..99ac6197be 100644 --- a/libavformat/dashdec.c +++ b/libavformat/dashdec.c @@ -2208,9 +2208,9 @@ static int dash_read_packet(AVFormatContext *s, AVPacket *pkt) if (cur->is_restart_needed) { cur->cur_seg_offset = 0; cur->init_sec_buf_read_offset = 0; + cur->is_restart_needed = 0; ff_format_io_close(cur->parent, &cur->input); ret = reopen_demux_for_component(s, cur); - cur->is_restart_needed = 0; } } return AVERROR_EOF; _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
