Transmuxing using gst encodebin

Jayanth K.P
Hi,
   I have a requirement to transmux an FLV stream (h.264/mp3) to
mpgets(h.264/mp3). I do not want to decode and mux.

How can this be achieved by using encodebin ? Or combination of
uridecodebin and encodebin .. Plz let me know.

Regards,
Jayanth

  Add the proper h264 and mp3 caps to the uridecodebin caps property (or
use the various uridecodebin signals to stop decoding)
  Create a container encoding profile for mpegts to which you'll add two
stream profiles, one for h264 and one for mp3 and then set that on
encodebin.
  You'll then be able to link the non-decoded pads of uridecodebin to
the sinkpads of encodebin.

  -base/tests/examples/encoding/ might help you.

Hi Edward,

I am running base/tests/examples/encoding/encoding application (this
test application uses uridecodebin and encodebin). Here feed08 is a
FLV file with h264 video. I am stopping the decoding by adding
video/x-h264 and audio/mpeg,mpegversion=4 to the cap of uridecodebin.

   ./encoding file:///home/jayanth/feed08 -o f1.ts -f video/mpegts -v
video/x-h264 -a audio/mpeg,mpegversion=4 --gst-debug-level=3

But somehow i am not able to get "autoplug-continue" signal .. Plz
suggest me what could be the issue.
