This reduces the need for an edit list; streams that start with e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid in mov/mp4) by shifting the dts values of all packets forward. This avoids the need for edit lists for such streams (while they still are needed for audio streams with encoder delay). This eases conformance with the DASH-IF interoperability guidelines.

Otherwise, it's never enabled unless the user explicitely enables it. Regression since 9ef5a2f. Fixes Ticket #6702.

This FFmpeg-specific "fuzzer fix" was never perfect, but now it stopped encoding of actual content with a big enough DTS shift. This returns the function to its original state of results before negative CTS offsets were added. I remember dealing with this function before, but somehow had forgotten about it during VDD. The test cases not tripping this over also didn't help.

Regression since 84b3f53.

This is not present in older bionic and therefore fails to build there, and the code is much simpler without it anyway.

Some V4L2 drivers fail to allocate buffers when sizeimage is not set to a max value. This is indeed the case for s5p-mfc [1] Most drivers should be able to calculate this value from the frame dimensions and format - or at least have their own default. However since this work around should not impact those drivers doing the "right thing" this commit just provides such a default. The calculations were extracted from the v4l2 driver used to develop the ffmpeg v4l2_m2m support [2].

Make easier to handle the polling function before we implement full threading support. (cherry picked from libav commit ca96016) Signed-off-by: James Almer <[email protected]>

Allows to specify the action to be performed when reading the last frame from the internal FIFO buffer. By default the last frame is written to filter output depending on the timestamp rounding method. When using "pass" action the last frame is passed through if input duration has not been reached yet. Examples using an input file with 25Hz, 1.4sec duration: - "fps=fps=1:round=near" generates an output file of 1sec - "fps=fps=1:round=near:eof_action=pass" generates an output file of 2sec Signed-off-by: Tobias Rapp <[email protected]>

Since af1761f ffmpeg waits for a frame in each stream before writing the output header. If we are using threaded decoding for attached pictures, we have to read till EOF to be able to finally flush the decoder and output the decoded frame. This essentially makes ffmpeg buffer all non-attached picture packets, which will cause a "Too many packets buffered for output stream" eventually. By forcing single threaded decoding, we get a frame from a single packet as well and we can avoid the error.

Signed-off-by: James Almer <[email protected]>

This has been deprecated in libva2 because hardware does not and will not support it. Therefore never consider it for decode, and for encode assume the user meant constrained baseline profile instead.

This is an ABI change in libva2: previously the Intel driver had this behaviour and it was implemented as a driver quirk, but now it is part of the specification so all drivers must do it.

This was duplicated between normal device creation and creation by derivation from a DRM device.

The message callbacks are library-safe in libva2, so we can now use them.

The initialisation should be common. For libmfx, it was previously happening in the derivation function and this moves it out. For VAAPI, it fixes some failures when deriving from a DRM device because this initialisation did not run.

Uses vaExportSurfaceHandle() from libva2.

This reverts commit c2d155e. GCC 6 incorrectly passes the configure test and then logs many warnings of the form: src/libavformat/dump.c: At top level: cc1: warning: unrecognized command line option ‘-Wno-bool-operation’
