FFmpeg
FFmpeg is a popular open-source multimedia framework commonly used for audio/video encode and decode functionality to a variety of codecs.
Yesterday's Activity
- hwcontext_vulkan: enable long vector extension
Lynne: This enables us to do some neat tricks. - vulkan: support shader compression
Lynne - vulkan: add support for precompiled shaders
Lynne - configure/make: support compile-time SPIR-V generation
Lynne - vulkan: switch to static allocation for temporary descriptor data
Lynne: Simplifies management, and the hardware is limited to 4 descriptor sets and whatever bindings. - avcodec/d3d12va_encode: add Region of Interest (ROI) support
stevxiao: This commit implements ROI (Region of Interest) encoding support for D3D12VA hardware encoders, enabling spatially-adaptive quality control for H.264, HEVC, and AV1 encoders. Query for `D3D12_VIDEO_ENCODER_RATE_CONTROL_FLAG_ENABLE_DELTA_QP` support during initialization to check whether the hardware support delta QP.
Other Activity This Week
- avcodec/bswapdsp: improve performance by remove manually unroll
Zhao Zhili: Manually unrolling loops increases code size, which can sometimes improve performance, but more often than not, it degrades performance. - checkasm/riscv: handle other float ABIs than double
Rémi Denis-Courmont: This splits out the integer and floating point handling to add support for software, single and quad float ABI's. - avformat/tls_gnutls: implement dtls handshake logic
Jack Lau: Get and set remote addr when dtls server mode. - lavfi/nlmeans: add aarch64 neon for compute_weights_line
Jun Zhao: Implement NEON optimization for compute_weights_line. Also update the function signature to use ptrdiff_t for stack arguments (max_meaningful_diff, startx, endx).

stevxiao: By default, the D3D12 video encoder uses MAXIMUM, which means no restriction—it uses the highest precision supported by the driver. Applications may want to reduce precision to improve speed or reduce power consumption. - avcodec/apv_parser: add support for AU assembly
James Almer - lavfi/nlmeans: add aarch64 neon for compute_weights_line
Jun Zhao: Implement NEON optimization for compute_weights_line. Also update the function signature to use ptrdiff_t for stack arguments (max_meaningful_diff, startx, endx). - avfilter/vf_drawvg: support color expressions as setvar/call arguments
Ayose: The arguments for `setvar` and `call` commands can be colors (like `#rrggbb`). - avformat/rawvideodec: add stride option to skip line padding
Zhao Zhili: Some tools like v4l2-ctl dump data without skip padding. - avcodec/bswapdsp: improve performance by remove manually unroll
