According to the sources:
f (input_chroma_subsampling != Y4M_CHROMA_420JPEG)
{
mjpeg_log (LOG_ERROR,
"Y4M-Stream is not 4:2:0. Other chroma-modes currently not allowed.
Sorry.");
exit (-1);
}
it's a feature.
Now why 420_JPEG is the only format supported is something I do not
the reason for. If anything was going to be supported 420MPEG2 would
have been a good choice.
You can try stubbing out that line - or change the 'if' to include
420_MPEG2 and see what happens.
Cheers,
