Description Sjoerd Simons 2006-04-19 10:10:18 UTC 
Hi,

  One would expect videotestsrc ! ffenc_mjpeg !  ffdec_mjpeg !  xvimagesink to display the original videotestsrc image nicely. Instead it shows a heavily distorted image. OTOH videotestsrc ! jpegenc !  ffdec_mjpeg !  xvimagesink works fine, so it seems to be a problem of ffenc_mjpeg

videotestsrc ! ffenc_mjpeg ! jpegdec ! xvimagesink fails too.
But at least it displays (garbled) moving picture, whereas ffenc_mjpeg ! ffdec_mjpeg only seems to display one frame.

So I'd say there's a problem with both ffenc_mjpeg and ffdec_mjpeg

Status update with latest cvs :
* videotestsrc ! ffenc_mjpeg !  ffdec_mjpeg !  xvimagesink : Displays garbled video
* videotestsrc ! ffenc_mjpeg ! jpegdec ! xvimagesink : Same as above
* videotestsrc ! jpegenc ! ffdec_mjpeg ! xvimagesink : Works like a charm
* videotestsrc ! jpegnec ! jpegdec ! xvimagesink : Works like a charm

So it seems the culprit is ffenc_mjpeg. Changing title accordingly

Interestingly, Lossless MJPEG works well:
gst-launch-0.10 videotestsrc ! ffenc_ljpeg ! ffdec_mjpeg ! xvimagesink

all combinations now work perfectly.
