Major

• Remove Support for Python 3.10
• Upgrade binary wheels to ffmpeg 8.1.2

Features

• Support HW encoding via a hwaccel parameter on OutputContainer.add_stream (e.g. h264_vaapi, h264_nvenc, h264_videotoolbox); software frames passed to encode are uploaded to the device automatically by @WyattBlue (#2156).
• Expose sw_format on VideoCodecContext, and allow configuring the software format of hardware encoders by @WyattBlue.
• Add options parameter to AudioResampler for passing libswresample options (e.g. resampler, filter_size, cutoff) by @WyattBlue (#2262).
• Support yuv420p10le in VideoFrame.to_ndarray and VideoFrame.from_ndarray by @WyattBlue (#1981).
• Add at parameter to Graph.push and Graph.vpush to push a frame to a single buffer source by index, for multi-input filters like overlay by @WyattBlue.
• find_best_pix_fmt_of_list now returns the loss as a PixFmtLoss enum.IntFlag instead of a plain int by @WyattBlue (#2300).
• Add Colorspace.BT2020 by @mark-oshea.
• BitStreamFilterContext now accepts a Codec or a codec-name str as in_stream to pin the input codec without a full Stream by @WyattBlue.

Fixes

• Fix VideoFrame.reformat (and to_ndarray/to_rgb/to_image) raising OSError Operation not supported on frames tagged with reserved or otherwise unsupported color_primaries/color_trc values (e.g. VP9 and NVDEC output); a transfer/primaries conversion is now only performed when explicitly requested by @WyattBlue (#2208).
• Fix add_mux_stream producing unwritable Matroska files by extracting codec extradata from the bitstream before the header is written by @WyattBlue (#2198).
• Encode GPU frames (e.g. CUDA frames from DLPack) directly with pix_fmt="cuda" by adopting the frame's hw_frames_ctx before opening the encoder by @WyattBlue (#2199).
• Fix a crash when reading VideoCodecContext.pix_fmt before it is set; it now returns None by @CarlosRDomin.
• Preserve frame attributes (pts, time_base, colorspace, etc.) when downloading hardware frames to system memory by @CarlosRDomin.
