Andriy Gelman fc3760a66d avcodec/v4l2_m2m_enc: Check encoder pix_fmt matches pix_fmt on device 
Fixes #8079

During initialization of a v4l2m2m device, the configured pix_fmt can be
different to the pix_fmt of the encoder (i.e. avctx->pix_fmt).

For example on the Odroid XU4:
./ffmpeg -f lavfi -i yuvtestsrc -codec:v h264_v4l2m2m out.h264

will configure the v4l2 encoder to pix_fmt nv21, whereas the input
frames will be yuv444p.

This commit checks that the configured v4l2 pix_fmt on device is the
same as avctx->pix_fmt. If they are different the initialization fails
and an error is returned. Tested on RPI4 and Odroid XU4.

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements 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, ismindex and qt-faststart.

Documentation

The offline documentation is available in the doc/ directory.

The online documentation is available in the main website and in the wiki.

Examples
