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
Note that ffmpeg is optimized for speed. You may not get comparable results across machines.
