Recode a motion-jpeg stream into mpeg-ts?

[Christophe Lohr]

Hi,
  Sorry, I have a final-user question... (I'm quite far to become a gst
developper...) So, may I ask my question here?

  I'm trying to recode the motion-jpeg stream for a network cam into an
mpeg-ts stream
(the ultimate wish is to watch this on a DLNA TV via Rygel, but this is
another step)

For now, I can watch the mjpeg stream via gstreamer:

$ gst-launch-1.0 uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg !
autovideosink

It's fine, I'm happy.

Now, I try to reencode the stream:

$ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg
! video/x-raw, framerate=25/1, width=640, height=480 !  videoconvert !
avenc_mpeg2video ! mpegtsmux ! tcpserversink
../..
/GstPipeline:pipeline0/GstCapsFilter:capsfilter1: caps = video/x-raw,
framerate=(fraction)25/1, width=(int)640, height=(int)480
ERROR: from element
/GstPipeline:pipeline0/GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source:

Additional debug info:

ERROR: pipeline doesn't want to preroll.

So, what's wrong?

Best regards
Christophe
