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 left.y4m -i right.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.
