Converting to y4m from other formats

You can use the ffmpeg tool to generate y4m from any of its supported video formats:

   ffmpeg -i video.webm -pix_fmt yuv420p video.y4m

Or just encode directly without an intermediate file:

   ffmpeg -i video.webm -pix_fmt yuv420p -f yuv4mpegpipe - | ./encoder_example - -o video.ogv
