2019-12-31avformat/mxfdec: Clear metadata_sets_count in mxf_read_close()Michael Niedermayer
This avoids problems if the function is called twice Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 13816a1d085fdb6598ea6dc92ed3a1e6aff0cc1f) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
2019-08-22avformat/mxfdec: do not ignore bad size errorsMarton Balint
The return value was unintentionally lost after 00a2652df3bf25a27d174cc67ed508b5317cb115. Signed-off-by: Marton Balint <cus@passwd.hu> (cherry picked from commit 6ee40dcb64c91cc9a4cb988408d8ed159dacdcfe)
2019-04-28avformat/mxfdec: fix and enhance RIP KLV length checksMarton Balint
KLV length is BER encoded (variable size), but the code assumed the encoding to always use 4 bytes. Fixes parsing Random Index Pack in samples/MXF/issue2160/PW0805A0V01.4C5B5636.EFA330.mxf. Signed-off-by: Marton Balint <cus@passwd.hu>
2019-04-28avformat/mxfdec: take into account run-in in find_partition_by_offsetMarton Balint
Also rename the function to find_partition_by_absolute_offset to make it clear offset is absolute. Signed-off-by: Marton Balint <cus@passwd.hu>
2019-04-28avformat/mxfdec: guess wrapping of tracks by other tracks with the same body sidMarton Balint
This affects the following samples: samples/ffmpeg-bugs/roundup/issue1775/av_seek_frame_failure.mxf samples/ffmpeg-bugs/trac/ticket1957/16ch.mxf samples/ffmpeg-bugs/trac/ticket5016/r0.mxf samples/ffmpeg-bugs/trac/ticket5016/r1.mxf samples/ffmpeg-bugs/trac/ticket5316/hq.MXF samples/ffmpeg-bugs/trac/ticket5316/hqx.MXF Some AVPacket->pos values are changed because for frame wrapped tracks we point to the KLV offset and not the data.

2019-04-28avformat/mxfdec: rework mxf_essence_container_endMarton Balint
We find the last essence container much faster if we go through the partitions backwards... Signed-off-by: Marton Balint <cus@passwd.hu>
2019-04-14avformat/mxfdec: use operational_pattern_ul instead of operational_pattern ↵Marton Balint
for metadata This makes it more consistent with other metadata keys. Signed-off-by: Marton Balint <cus@passwd.hu>
2019-04-11avformat/mxfdec: export operational pattern UL as file metadataMarton Balint
Can be useful for API users as ffmpeg/libavformat can't properly support some operational patterns. Signed-off-by: Marton Balint <cus@passwd.hu>

2018-09-05avformat/mxfdec: do not use sound essence descriptor quantization bits for ↵Marton Balint
bits_per_coded_sample It refers to the uncompressed quantization, therefore is not correct for AAC. Also change mxf_set_pts to work based on current edit unit if bits_per_coded_sample is not available. Fixes error messages in the sample of ticket #7366. Signed-off-by: Marton Balint <cus@passwd.hu>
