* avutil/buffer: Avoid allocation of AVBuffer when using buffer poolAndreas Rheinhardt2021-09-18
| | | | | | | | Do this by putting an AVBuffer structure into BufferPoolEntry and reuse it for all subsequent uses of said BufferPoolEntry. Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avfilter/vf_zscale: Don't make assumptions about zimg's range enumsAndreas Rheinhardt2021-09-18
| | | | | | | | | zimg's color range enum values are off-by-one compared to ours; therefore the code just adds one when converting from theirs to ours. Yet this is not how one should deal with enums; use a switch instead. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/libsrt: remove url_get_file_handle implementationZhao Zhili2021-09-18
| | | | | | | | SRTSOCKET is an abstraction designed by libsrt, it's not guaranteed to be a real file descriptor. Even if it is, it should not be operated directly outside of libsrt. Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/libsrt: log streamid in listener modeZhao Zhili2021-09-18
| | | | | | | | | It's useful for test client which pass streamid to ffmpeg/ffplay. For example, use ffmpeg to test streamid support in VLC: ./ffmpeg -v info -re -i foo.mp4 -c copy -f mpegts -mode listener srt://127.0.0.1:9000 ./vlc srt://127.0.0.1:9000?streamid=foobar Signed-off-by: Marton Balint <cus@passwd.hu>
* avformat/mpegts: fixes overflow when parsing the PMTNicolas Jorge Dato2021-09-18
| | | | | | | | | | When a possible overflow was detected, there was a break to exit the while loop. However, it should have already substracted 2 bytes from program_info_length (descriptor ID + length). Fixes ticket #9422. Signed-off-by: Marton Balint <cus@passwd.hu>
* libavfilter/x86/vf_gblur: correct the order of loop stepWu Jianhua2021-09-18
| | | | | | | | | | | The problem was caused by if the width of the processed block minus 1 is a multiple of the aligned number the instruction jle .bscale_scalar would skip the Optimized Loop Step, which will lead to an incorrect sampling when specifying steps more than 1. Move the Optimized Loop Step after .bscale_scalar to ensure the loop step is enabled. Signed-off-by: Wu Jianhua <jianhua.wu@intel.com>

* avformat/utils: Move demuxing code out into a new fileAndreas Rheinhardt2021-09-17
| | | | | | | | | | | | | libavformat/utils.c has over 4800 lines and is supposed to contain "various utility functions for use within FFmpeg". In reality it contains all that and the whole demuxing core of libavformat. This is especially bad, because said file includes the FFMPEG_VERSION (the git commit sha) so that it is rebuilt whenever the commit HEAD points to changes. Therefore this commit makes it smaller by moving the demuxing code out to a new file, demux.c (in analogy to mux.c for the muxing code).

| | | | | | | | | | | | libavformat/utils.c has over 5500 lines and is supposed to contain "various utility functions for use within FFmpeg". In reality it contains all that and the whole demuxing+seeking core of libavformat. This is especially bad, because said file includes the FFMPEG_VERSION (the git commit sha) so that it is rebuilt whenever the commit HEAD points to changes. Therefore this commit starts making it smaller by factoring the seeking code out. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.
