<pre>Hello everybody,
Since I could't find anything about this problem I had to create a new post.
So I'm using a RaspberryPi to generate h264 videos from a sequence of jpegs
that I get from a webcam.
*this is my current pipe:*
gst-launch-1.0 -e v4l2src do-timestamp=true device=/dev/video0 ! videorate
! image/jpeg,width=640,height=480,framerate=15/1 ! jpegparse ! jpegdec
! omxh264enc ! video/x-h264,framerate=15/1, speed-preset=medium
! h264parse ! mp4mux ! filesink location= video.mp4
It is working like a charm, except that the videos can only be played with
chrome or VLC.
What I'm trying is to decode it again using gstreamer afterwards using the
following pipe:
*gst-launch-1.0 playbin uri=<a moz-do-not-send="true">file://PATH_TO_FILE/video.mp4*</a>
And it ends the execution before showing the first frame.
*Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

I even tried to use qtmux instead of mp4mux, but the results are the same.
Does anyone had the same problem ?
Thanks so far
