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
- avformat/movenccenc: add support for CENC AV1 encryption
James Almer
Other Activity This Week
- avcodec/ffv1: Implement 2D RLE for remap
Michael Niedermayer: ATM this performs as well or better as any other algorithm tried. - avcodec/ffv1: 32-bit float sample support
Michael Niedermayer - ffmpeg: add per-stream input option drop_changed
Gyan Doshi: This is a replacement in ffmpeg for the deprecated avcodec flag AV_CODEC_FLAG_DROPCHANGED. This option is meant to be used when the filtergraph should not be reinited upon input parameter changes as that leads to loss of state in the filtergraph potentially leading to broken or aborted output, e.g. - swscale/x86/rgb2rgb: optimize AVX2 version of uyvytoyuv422
Shreesh Adiga: Currently the AVX2 version of uyvytoyuv422 in the SIMD loop does the following: 4 vinsertq to have interleaving of the vector lanes during load from memory. - avcodec/amfenc: add smart access video option
Evgeny Pavlov: This commit adds option for enabling SmartAccess Video (SAV) in AMF encoders.

Manuel Lauss: Handle STOR/FTCH the same way the RA1 game engine does: On STOR, save the next following FOBJ (not the decoded image) in a buffer; decode it on FTCH. - swscale/output: add support for NV20
James Almer - swscale/input: add support for NV20
James Almer - avcodec/ffv1: Add GRAYF16 support

Most Popular In The Past Month
- vulkan: add support for AV_PIX_FMT_GRAY32
Lynne - FFHWAccel: add buffer_ref argument to start_frame
Lynne: This commit adds a reference to the buffer as an argument to start_frame, and adapts all existing code. - vulkan: add support for AV_PIX_FMT_GBRAP32
Lynne - ffv1: add a Vulkan-based decoder
Lynne: This patch adds a fully-featured level 3 and 4 decoder for FFv1, supporting Golomb and all Range coding variants, all pixel formats, and all features, except for the newly added floating-point formats. On a 6000 Ada, for 3840x2160 bgr0 content at 50Mbps (standard desktop recording), it is able to do 400fps. - avformat/movenccenc: add support for CENC AV1 encryption
James Almer - ffv1dec: add support for hwaccels
Lynne: This commit adds support for hardware accelerated decoding to the decoder. - hwcontext_vulkan: add support for mapping multiplane images into CUDA
Lynne: This patch refactors the CUDA import code to allow for Vulkan images with multiple planes to be mapped. Currently, a driver bug exists which causes NV12 images to be mapped incorrectly when the memory being mapped contains both planes, the issue has been reported to NVIDIA. - avcodec/hqxvlc: Avoid hardcoded RL VLC table
Andreas Rheinhardt: hqxvlc.c contains sort-of run-length VLCs in hardcoded form; they amount to 26688 elements, taking 104KiB. - swscale/input: add support for YAF16 and YAF32
James Almer - avfilter/vsrc_testsrc: add support for semi planar formats to yuvtestsrc
