NAME

   yuvplay - Display YUV4MPEG2 streams (using SDL)

SYNOPSIS

   yuvplay [options]

DESCRIPTION

   yuvplay  produces  on-screen  playback  of  a YUV4MPEG2 stream which is
   provided  to  stdin,  typically  through  piping  from  the  stdout  of
   lavpipe(1), lav2yuv(1), mpeg2dec(1) or a similar program.  It should be
   noted that for pure playback  lavplay  should  be  a  superior  option.
   yuvplay is intended primarily as a debugging or diagnostic utility when
   setting up video processing pipelines.

OPTIONS

   yuvplay accepts the following options:

   -s WxH  The size of the SDL window.  By default, it uses  the  size  of
           the  input  video  stream scaled to yield 1:1 pixels (using the
           sample aspect ratio encoded in the  stream  header).   However,
           you  can  specify any size you want.  WxH is the width x height
           of the scaled window.

   -ttitle Set the window title.

   -f num  Override the framerate specified in the input stream header.

   -c      By default, yuvplay will try to play at the  framerate  of  the
           input  movie.  With this option, yuvplay will just play all the
           frames as fast as it can.

   -v [0,1,2]
           Set the verbosity of user feedback.  Default is  "1":   errors,
           warnings, and info messages.
