What is encoding?

mplayer debug 32 motion vector

-lavdopts <option1:option2:...> (DEBUG CODE) Specify libavcodec decoding parameters. Separate multiple options with a colon.

      EXAMPLE:
         -lavdopts gray:skiploopfilter=all:skipframe=nonref

      Available options are:

 debug=<value>
      Display debugging information.
         0: disabled
         1: picture info
         2: rate control
         4: bitstream
         8: macroblock (MB) type
         16: per-block quantization parameter (QP)
         32: motion vector
         0x0040: motion vector visualization (use -noslices)
         0x0080: macroblock (MB) skip
         0x0100: startcode
         0x0200: PTS
         0x0400: error resilience
         0x0800: memory management control operations (H.264)
         0x1000: bugs
         0x2000: Visualize quantization parameter (QP), lower QP are tinted greener.
         0x4000: Visualize block types.

 vismv=<value>
      Visualize motion vectors.
         0: disabled
         1: Visualize forward predicted MVs of P-frames.
         2: Visualize forward predicted MVs of B-frames.
         4: Visualize backward predicted MVs of B-frames.
