ERROR: from element /pipeline0/mfwgstvpu_dec0: fatal error

Hi all,

I'm working to make  Video streaming working on my iMX27 board and encountered this problem.

I am trying to stream a video using imx27 but i have a problem in streaming using gstreamer.
The kernel I'm using is the one that Freescale gives for iMX27 av.board and it's a 2.6.22 with iMX27 patches from Freescale.

Any kind of help is appreciated!

Re: ERROR: from element /pipeline0/mfwgstvpu_dec0: fatal error

try

gst-launch filesrc -v location=/video/test.mp4 ! mfw_mp4demuxer
name=demux demux. ! mfw_vpudecoder codec-type=std_mpeg4 ! fakesink

If it is OK, it is video sink error. Otherwise, decoder has something wrong.

Also, add " --gst-debug=2" at the end of cmd line may print more log message.

gst-launch filesrc -v location=/video/test.mp4 ! mfw_mp4demuxer
name=demux demux. ! mfw_vpudecoder codec-type=std_mpeg4 ! mfw_v4lsink --gst-debug=
mfw_mp4demuxer:4,mfw_v4lsink:4

I am not sure it is mfw_vpudecoder and mfw_v4lsink in debug list, you can find it with
gst-inspect --gst-debug-help | grep vpudecoder

Hi ,

The problem was from the kernel configuration of the video device. Now the gstreamer works well. Thanks.
