* lavfi: add a new filtergraph parsing APIAnton Khirnov2023-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Callers currently have two ways of adding filters to a graph - they can either - create, initialize, and link them manually - use one of the avfilter_graph_parse*() functions, which take a (typically end-user-written) string, split it into individual filter definitions+options, then create filters, apply options, initialize filters, and finally link them - all based on information from this string. A major problem with the second approach is that it performs many actions as a single atomic unit, leaving the caller no space to intervene in between. Such intervention would be useful e.g. to - modify filter options; - supply hardware device contexts; both of which typically must be done before the filter is initialized. Callers who need such intervention are then forced to invent their own filtergraph parsing, which is clearly suboptimal. This commit aims to address this problem by adding a new modular filtergraph parsing API. It adds a new avfilter_graph_segment_parse() function to parse a string filtergraph description into an intermediate tree-like representation (AVFilterGraphSegment and its children). This intermediate form may then be applied step by step using further new avfilter_graph_segment*() functions, with user intervention possible between each step.
* lavfi/avfilter: track whether a filter has been initializedAnton Khirnov2023-01-18
| | | | Refuse to link uninitialized filters or initialize a filter twice.
* lavfi/avfilter: export process_options()Anton Khirnov2023-01-18
| | | | | | | Also, replace an AVFilterContext argument with a logging context+private class, as those are the only things needed in this function. Will be useful in future commits.

* lavc/bitstream: avoid UB in bits_{read,peek}_signed(0)Anton Khirnov2023-01-18
| | | | | | | | | | 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

* lavc/libvpx: increase thread limit to 64OvchinnikovDmitrii2023-01-17
| | | | | | | | | | | | | | | | | | | | | | 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>

* lavfi/qsv: use QSVVPPContext as base context in vf_vpp_qsv/vf_overlay_qsvHaihao Xiang2023-01-17
| | | | | | | | | | | | | | 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>
