* avformat/ffmdec: replace most codec uses by codecparMichael Niedermayer2016-12-03
| | | | | | | This is a bit messy as codecar does not support AVOptions so we need to use AVCodecContext where AVOptions are required and copy back and forth. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat/ffmenc: Make ffm_write_header_codec_ctx() use codecparMichael Niedermayer2016-12-02
| | | | | | | | | This would be simpler if codecpar supported AVOptions modern ffserver should be unaffected by this, older ffserver which required the muxer to directly access the encoder could have issues with this, but this direct access is just wrong and unsafe Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* avformat/ffmenc: Drop ffm_write_header_codec_private_ctx()Michael Niedermayer2016-12-02
| | | | | | | | | This accesses the private encoder context, it should not be used by the current ffserver it may affect old ffserver versions but i believe there is consens that accessing the private encoder context from the muxer is completely wrong.

* matroskadec: partly revert "demux relevant subtitle packets after a seek"Rainer Hochecker2016-12-02
| | | | | | | | | | | | | This reverts parts of c16582579b1c6f66a86615c5808cd5b2bf17be73. The hard coded 30 seconds are a lot, and finishing the seek can takes several seconds when the source is on a network share. Remove this code entirely, because it does more bad than good.

* mov: Evaluate the movie display matrixVittorio Giovara2016-11-30
| | | | | | | | | This matrix needs to be applied after all others have (currently only display matrix from trak), but cannot be handled in movie box, since streams are not allocated yet. So store it in main context, and apply it when appropriate, that is after parsing the tkhd one. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

* matroskadec: prevent access of elements after freeingMichael Schenk2016-11-30
| | | | | | | | | | Using the decode interrupt feature of ffmpeg may cause crashes by accessing previously freed pointers in matroska_read_close. To prevent this reset nb_elem to zero after freeing the elements, because ffmpeg normally tests for nb_elem. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
