* avcodec/nvenc: refactor dts calculation logicTimo Rothenpieler2020-05-02
| | | | | | | | | | | | | The old approach used some highly complex delta computation math and output-delaying. I do not remember what the initial reasoning behind that was, but given that we can just offset the dts by the amount of bframes, it seems wholy unnecessary. This leaves open an issue with VFR content, for which some more complex logic might be needed. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>

* avcodec/v4l2_context: Log warning when all capture buffers are in userspaceAndriy Gelman2020-04-30
| | | | | | | | | | | | | | | | v4l2_m2m uses device memory mapped buffers to store dequeued frames/packets (reference counted by AVBufferRef). When the reference count drops to zero, the buffer ownership is returned back to the device, so that they can re-filled with frames/packets. There are some cases when all the capture buffers are in userspace (i.e. due to internal buffering in ffmpeg). On the s5p-mfc this causes an infinite wait when polling to dequeue the buffers, which can be prevented by increasing the total number of buffers. This commit adds a warning when all the capture buffers are dequeued. Reviewed-by: Ming Qian <ming.qian@nxp.com> Signed-off-by: Andriy Gelman <andriy.gelman@gmail.com>
* avcodec/avpacket: Don't write into non-writable bufferAndreas Rheinhardt2020-04-30
| | | | | | | | | | The data of an AVPacket may be a part of the data of an AVBufferRef; Therefore av_grow_packet() doesn't reallocate if the available space in the actual buffer is sufficient for the enlargement. But given that it also zeroes the padding it also needs to make sure that the buffer is actually writable; this commit implements this.

* libavcodec/libx264: fix reference frame computation based on levelJosh Brewster2020-04-29
| | | | | | | | | | | | | | | The current implementation allows passing levels to libavcodec as integers (such as "31" instead of "3.1"). However, in this case, the maximum reference frame value per level was ignored because libavcodec converted the string to 310 instead of 31. Since libx264 has correctly parsed the level to int (x4->params.i_level_idc), we should rely on this value instead of attempting to parse the level string on our own.
