Major

• Limited API binary wheels are now built.
• 3.13t (free-threading) wheels are be dropped because of storage limitations. Use 3.14t or 3.13.
• When an FFmpeg C function indicates an error, raise av.ArgumentError instead of ValueError/av.ValueError. This helps disambiguate why an exception is being thrown.
• Save space by removing libaom (av1 encoder/decoder); dav1d, stvav1, and hardware, are available alternatives.

Features

• Add OutputContainer.add_mux_stream() for creating codec-context-free streams, enabling muxing of pre-encoded packets without an encoder, addressing [#1970] by @WyattBlue.
• Use zero-copy for Packet init from buffer data by @WyattBlue in (#2199).
• Expose AVIndexEntry by @Queuecumber in (#2136).
• Preserving hardware memory during cuvid decoding, exporting/importing via dlpack by @WyattBlue in (#2155).
• Add enumerate_input_devices and enumerate_output_devices API by @WyattBlue in (#2174).
• Add ColorTrc and ColorPrimaries enums; add color_trc and color_primaries properties to VideoFrame; add dst_color_trc and dst_color_primaries parameters to VideoFrame.reformat(), addressing [#1968] by @WyattBlue in (#2175).
• Add multithreaded reformatting and reduce Python overhead by replacing sws_scale with sws_scale_frame, skipping unnecessary reformats, and minimizing Python interactions by @lgeiger.
• Prevent data copy in VideoFrame.to_ndarray() for padded frames by @lgeiger in (#2190).

Fixes

• Fix [#2149] by @WyattBlue in (#2155).
• Fix packet typing based on stream and specify InputContainer.demux based on incoming stream by @ntjohnson1 in (#2134).
• Fix memory growth when remuxing with add_stream_from_template by skipping avcodec_open2 for template-initialized codec contexts, addressing [#2135] by @WyattBlue).
• Explicitly disable OpenSSL in source builds (scripts/build-deps) to prevent accidental OpenSSL linkage that breaks FIPS-enabled systems, addressing [#1972].
• Add missing SWS_SPLINE interpolation by @lgeiger in (#2188).
