Aman Gupta 7bb6898b16 avcodec/v4l2_m2m: fix av_pix_fmt changing when multiple /dev/video* devices are probed 
On the RPI, three different /dev/video devices exist (decoder, scaler, encoder).

When probing the devices in order, the originally requested pix fmt
would be mutated causing the wrong one to be chosen when a matching
device was finally found.

  • 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.
