Description Alex Kuklin 2011-07-31 12:18:33 UTC 
Couldn't find data stream multipartdemux to handle.

File created by multipartmux isn't ok too:

$ LANG=C gst-launch videotestsrc ! video/x-raw-yuv, framerate='(fraction)'5/1 ! jpegenc ! multipartmux  ! filesink location=/tmp/test.multipart

$  LANG=C gst-launch -v filesrc location=/tmp/test.multipart ! multipartdemux ! image/jpeg,width=320,height=240 ! ximagesink

This is expected behaviour, ximagesink can not handle image/jpeg so the dynamic pad from multipartdemux is never linked to the capfilter.

Maybe you should try without the wrong capsfilters and with the right decoders. This works for me:

gst-launch videotestsrc ! video/x-raw-yuv, framerate='(fraction)'5/1 ! jpegenc ! multipartmux ! filesink location=multipart.dump

and

gst-launch filesrc location=multipart.dump ! multipartdemux ! jpegdec ! xvimagesink
