Marton Balint 418c90faac ffplay: fix -x and -y options when only one of them is used 
Previously if only -y was used then nothing happened, if only -x then zero
window height was set which is undefined in SDL and caused a black window.

From now on if only one dimension is set we calculate the other based on
size/aspect of the shown content.

  • 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.
