Andreas Rheinhardt 95b681eafd avcodec/vp9: Remove vp9_free_entries() 
Now that the mutexes and conditions are only initialized and destroyed
once, said function only had one purpose: free the entries array.
Given that vp9_alloc_entries() already does this if the array is already
allocated it is unnecessary to call vp9_free_entries() anywhere except
when closing. And then one can just inline the one free into
vp9_decode_free().

  • 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.
