[gst-devel] ERROR: from element /pipeline0/mfwgstvpu_dec0: fatal error

[Nie Jun]

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.

or

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
