Merging two y4m videos side-by-side
To combine two y4m videos into a single video (with the input videos displayed side-by-side), do:
ffmpeg -i uncompressed.y4m -i compressed.y4m -filter_complex "[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; \
[1:v]setpts=PTS-STARTPTS[fg]; [bg][fg]overlay=w" a_b_compare.y4m
Substitute ffmpeg with avconv if needed.
