Remove the static supported_formats[] allowlist from hwcontext_cuda. cuda_frames_get_constraints() now iterates all registered pixel formats and includes every non-hwaccel, non-palette format. cuda_frames_init() validates with av_pix_fmt_desc_get() instead of checking against the allowlist. Palette formats have a special-cased use of plane[1] for the palette itself and it's not worth the hassle of supporting in an otherwise clean generic copy loop. Also add a roundtrip test that uploads a deterministic byte pattern to CUDA, downloads it back, and verifies the data match. This tests all non-hwaccel pixel formats. The test is gated on CONFIG_CUDA.

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.
Libraries
libavcodecprovides implementation of a wider range of codecs.libavformatimplements streaming protocols, container formats and basic I/O access.libavutilincludes hashers, decompressors and miscellaneous utility functions.libavfilterprovides means to alter decoded audio and video through a directed graph of connected filters.libavdeviceprovides an abstraction to access capture and playback devices.libswresampleimplements audio mixing and resampling routines.libswscaleimplements color conversion and scaling routines.
Tools
- ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
- ffplay is a minimalistic multimedia player.
- ffprobe is a simple analysis tool to inspect multimedia content.
- Additional small tools such as
aviocat,ismindexandqt-faststart.
