MAINT: Bump av from 17.1.0 to 18.1.0

[dependabot]

Bumps av from 17.1.0 to 18.1.0.

Release notes

Sourced from av's releases.

v18.1.0

Features

• Infer the specific stream and codec context types for all FFmpeg encoder names in type-checked code by @​WyattBlue.
• Add CodecContext.supported_options to discover generic and codec-specific options by @​WyattBlue (#2032).
• Add Packet.rescale_ts() to rescale packet PTS, DTS, and duration to a new AVRational time base by @​WyattBlue.
• Support reusing the thread's current CUDA context via a current_ctx flag on CudaContext and VideoFrame.from_dlpack, for interop with libraries like PyTorch that initialize CUDA first by @​Yozer (#2339).
• VideoFrame.from_dlpack no longer requires restating primary_ctx/current_ctx when passing an explicit cuda_context; the flags are only validated when explicitly given by @​WyattBlue.
• Support passing an explicit CUDA stream to FFmpeg CUDA operations, including NVENC input and output, via a cuda_stream parameter on CudaContext; currently limited to logical CUDA device 0 by @​Yozer (#2360).
• Add av.AVRational, an exact rational number stored as two int32s that mirrors FFmpeg's AVRational. Codec.frame_rates now holds these rather than fractions.Fraction, and every setter that accepts a Fraction also accepts an AVRational. Unset rational attributes are falsy, so test them with if not stream.time_base: rather than is None by @​WyattBlue.
• Add Frame.metadata, the metadata FFmpeg attaches to a frame, by @​WyattBlue.
• Add CodecContext.level by @​WyattBlue.
• Add VideoCodecContext.field_order by @​WyattBlue.
• VideoFrame.save now forwards keyword arguments to the encoder, letting callers trade file size for speed (e.g. pred="none" or compression_level=1 for PNG, qscale=2 for JPG) by @​WyattBlue.
• Add InputContainer.start_time_realtime, the stream's start time in microseconds since the Unix epoch, which RTSP derives from RTCP sender reports, by @​WyattBlue (#2365).

Fixes

• Fix VideoFrame.save raising AttributeError when given a Path rather than a str by @​WyattBlue.
• Fix a frame rate assigned to a VideoStream after add_stream being dropped from the output; the codec context's frame rate is now copied to the stream before the header is written by @​WyattBlue (#2301).
• Prevent crashes and corrupted output when structural codec properties are changed after an output stream has been opened by @​WyattBlue, reported by @​oakaigh (#2232).
• Fix a crash when using a stream that has no CodecContext (a demuxed stream with no available decoder, such as one from a truncated file, or a stream created by add_mux_stream); decoding now raises DecoderNotFoundError, encoding now raises EncoderNotFoundError, and BitStreamFilterContext accepts such a stream as out_stream by @​WyattBlue, reported by @​justinrmiller (#2344).

Misc

• Support building from source against FFmpeg 9.0 by @​WyattBlue. The binary wheels still ship FFmpeg 8.1.2.

New Contributors

• @​Yozer made their first contribution in PyAV-Org/PyAV#2339

Full Changelog: PyAV-Org/PyAV@v18.0.0...v18.1.0

v18.0.0

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.
