* libavformat/dashenc: Reduce confusion in par error messageChris Miceli2020-08-31
| | | | | | | | | | In ticket #8754 there is discourse surrounding the error message which is printed upon a mismatched aspect ratio in derived encodings. This should make it clearer to the user as to the issues which they are experiencing.

* avformat: only allow a single bitstream filter when muxingMarton Balint2020-04-26
| | | | | | | | | | | | Current muxers only use a single bitstream filter, so there is no need to maintain code which operates on a list of bitstream filters. When multiple bitstream filters are needed muxers can simply use a list bitstream filter. If there is a use case in the future when different bitstream filters should be added at subsequent packets then a new API possibly involving reconfiguring the list bitstream filter can be added knowing the exact requirements.

* dashenc: check pts to prevent division by zero errorAlfred E. Heggestad2020-01-31
| | | | | | | | | | | | | | | | | | this usecase will cause a division by zero trap: 1. dashenc has received one frame 2. os->max_pts and os->start_pts have same value 3. delta between max_pts and start_pts is 0 4. av_rescale_q(0, x, y) returns 0 5. this value is used as denominator in division 6. Bang! -> segfault this fix checks that max_pts > start_pts. the fix has been tested and works. Signed-off-by: Alfred E.

* avformat/dashenc: Fix leak of AVFormatContext on errorAndreas Rheinhardt2020-01-08
| | | | | | | | | | | The Dash muxer uses submuxers and when one such submuxer has been allocated, it is initially only stored in a temporary variable. Therefore it leaks if an error happens between the allocation and storing it permanently. This commit changes this.
