| | | | | Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Limin Wang <lance.lmwang@gmail.com>
* avformat/mxfdec: Correct confusing struct tagAndreas Rheinhardt2020-03-30
| | | | | | | | Don't use typedef struct MXFTrack {...} MXFTimecodeComponent, in particular given the fact that MXFTrack is a type of its own. Reviewed-by: Tomas Härdin <tjoppen@acc.umu.se> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avformat/mxfdec: do not ignore bad size errorsMarton Balint2019-08-22
| | | | | | | The return value was unintentionally lost after 00a2652df3bf25a27d174cc67ed508b5317cb115. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/mxfdec: fix and enhance RIP KLV length checksMarton Balint2019-04-28
| | | | | | | | | 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>
* avformat/mxfdec: take into account run-in in find_partition_by_offsetMarton Balint2019-04-28
| | | | | | | 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>
* avformat/mxfdec: guess wrapping of tracks by other tracks with the same body sidMarton Balint2019-04-28
| | | | | | | | | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/mxfdec: rework mxf_essence_container_endMarton Balint2019-04-28
| | | | | | | We find the last essence container much faster if we go through the partitions backwards... Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/mxfdec: export operational pattern UL as file metadataMarton Balint2019-04-11
| | | | | | | Can be useful for API users as ffmpeg/libavformat can't properly support some operational patterns. Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | | | | | | | 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>
