Stefano Sabatini	843a446713	ffprobe: fix data hash rendering Print data hash before side data list, fix wrong nesting level of data hash element. In particular, fix trac issue: http://trac.ffmpeg.org/ticket/7217	2 years ago
Stefano Sabatini	b6219c9114	ffprobe: use pkt->dts to compute interval ts when pts is missing For some samples the pkt->pts is always missing, use the pkt->dts instead. Fix trac issue: http://trac.ffmpeg.org/ticket/4427	2 years ago
Mark Thompson	aaa49a7a42	cbs_av1: Remove constraint on MDCV luminance values While desiring min to be less than max feels entirely sensible, unfortunately the standard does not actually have this requirement.	2 years ago

Leo Izen	9d5e66942c	avcodec/libjxldec: fix gamma22 and gamma28 recognition Gamma 2.2 and Gamma 2.8 are tagged in the file as 0.45455 and 0.35714, respectively (i.e. 1/2.2 and 1/2.8). Trying to identify them as 2.2 and 2.8 instead of these values will cause the transfer function to not properly be recognized. This patch fixes this.	2 years ago

Anton Khirnov	ba36e6ed52	lavc/tests/bitstream: test bits__signed_nz and bits_peek_signed	2 years ago
Anton Khirnov	0b33310cd0	lavc/bitstream: avoid UB in bits_{read,peek}_signed(0) bits__signed(0) will currently invoke an undefined shift by 8 sizeof(int). Add bits__signed_nz() that only works for n>0, analogous to bits_read_nz(). Add an explicit check for n=0 in bits__signed(). Found-by: James Almer	2 years ago

OvchinnikovDmitrii	c13d959343	lavc/libvpx: increase thread limit to 64 This change improves the performance and multicore scalability of the vp9 codec for streaming single-pass encoded videos by taking advantage of up to 64 cores in the system. The current thread limit for ffmpeg codecs is 16 (MAX_AUTO_THREADS in pthread_internal.h) due to a limitation in H.264 codec that prevents more than 16 threads being used. Experiments show that increasing the thread limit to 64 for vp9 improves the performance for encoding 4K raw videos for streaming by up to 47% compared to 16 threads, and from 20-30% for 32 threads, with the same quality as measured by the VMAF score. Rationale for this change: Vp9 uses tiling to split the video frame into multiple columns; tiles must be at least 256 pixels wide, so there is a limit to how many tiles can be used. The tiles can be processed in parallel, and more tiles mean more CPU threads can be used. 4K videos can make use of 16 threads, and 8K videos can use 32. Row-mt can double the number of threads so 64 threads can be used. Signed-off-by: James Zern <jzern@google.com>	2 years ago

Haihao Xiang	7491545320	lavfi/qsv: use QSVVPPContext as base context in vf_vpp_qsv/vf_overlay_qsv The same members between QSVVPPContext and VPPContext are removed from VPPContext, and async_depth is moved from QSVVPPParam to QSVVPPContext so that all QSV filters using QSVVPPContext may support async depth. In addition, we may use QSVVPPContext as base context in other QSV filters in the future so that we may re-use functions defined in qsvvpp.c for other QSV filters. This commit shouldn't change the functionality of vpp_qsv / overlay_qsv. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>	2 years ago
