Description Enrico Pelo 2019-09-05 13:29:07 UTC

hello,I’m building rpi4 image with poky for qt development but I’m not able to play mp4 h264 video files with gstreamer pipeline gst-launch-1.0 -e -vvv filesrc location=foo.mp4 ! qtdemux ! queue ! h264parse ! v4l2h264dec capture-io-mode=4 ! kmssink is there someone that can help me?
Gstreamer does not start play and after control-c I see 
Error: pipeline doesn’t want to petroli

But this pipeline
 gst-launch-1.0 -e -vvv filesrc location=big_buck_bunny_720p_h264.mov ! qtdemux ! queue ! h264parse ! v4l2h264dec capture-io-mode=4 ! kmssink

Works great in gpu

Any ideas?
