it's tricky

the codecs actually return NULL, meaning no frame available, but the
yuv2mpeg vo was patched some time ago to save even empty frames, to
avoid a-v desync (ie. length change) when converting files
(for divx->mpeg2enc conversion with mencvcd or so).

so it should be fixed, to save empty frames only after first non-empty
