When the video decoding, I found the video overlay a vertical green stripes frame, why?

[taowang]

When the video decoding, I found the video overlay a vertical green stripes  frame, normal frame and green striped frame has been alternately flashing. I used imx51, please help me why? how to deal with it ? thank you very much.

i used vpu lib to decode the h.264 raw data, then use v4l2 to display decoded frame. how can i get the reason to the problem?

Do you observer the same when using gstreamer? try playing (decoding + displaying) the file using

gst-launch playbin2 uri=file://<full path including the media file name>

If it looks bad with the above command, so there may be an issue with the HW decoder.

POst the pipeline you used (add -v to check the caps and also share this log)

I met the same problem, could you sent the detail how to get the log?

is -v a command line parameter? which command should i do?

Do we konw  the problem is V4L2 or vpu error for sure?

-v is a gst-launch parameter, and indicates to show caps for all sinks and sources.
