gst-libs/gst/riff/riff-read.c: Additional pad usability check.
Original commit message from CVS: 2004-01-25 Ronald Bultje <rbultje@ronald.bitfreak.net> * gst-libs/gst/riff/riff-read.c: (gst_riff_read_info): Additional pad usability check. * gst/mpeg1videoparse/gstmp1videoparse.c: (gst_mp1videoparse_init), (mp1videoparse_find_next_gop), (gst_mp1videoparse_time_code), (gst_mp1videoparse_real_chain): Fix MPEG video stream parsing. The original plugin had several issues, including not timestamping streams where the source was not timestamped (this happens with PTS values in mpeg system streams, but MPEG video is also a valid stream on its own so that needs timestamps too). We use the display time code for that for now. Also, if one incoming buffer contains multiple valid frames, we push them all on correctly now, including proper EOS handling. Lastly, several potential segfaults were fixed, and we properly sync on new sequence/gop headers to include them in next, not previous frames (since they're header for the next frame, not the previous). Also see #119206. * gst/mpegaudioparse/gstmpegaudioparse.c: (gst_mp3parse_chain), (bpf_from_header): Move caps setting so we only do it after finding several valid MPEG-1 fraes sequentially, not right after the first one (which might be coincidental). * gst/typefind/gsttypefindfunctions.c: (mpeg1_sys_type_find), (mpeg_video_type_find), (mpeg_video_stream_type_find), (plugin_init): Add unsynced MPEG video stream typefinding, and change some probability values so we detect streams rightly. The idea is as follows: I can have an unsynced system stream which contains video. In the current code, I would randomly get a type for either system or video stream type found, because the probabilities are being calculated rather randomly. I now use fixed values, so we always prefer system stream if that was found (and that is how it should be). If no system stream was found, we can still identity the stream as video-only.
