Is there a bug with the 'avenc_mpeg1video' element? It seems that when this
element is placed downstream of an appsrc element, it cannot encode

//video stream does not work
appsrc name=src ! videoconvert ! avenc_mpeg1video ...

//video stream does work
videotestsrc ! videoconvert ! avenc_mpeg1video ...

Inserting caps: 'video/x-raw,format=I420,width=640,height=480' after
videoconvert does not help.

I am positive that the appsrc element works because everything works
properly with x264enc encoding.

Thanks in advance.
