I am creating simple playback pipeline.

I noticed video decoding problem when playback pipeline is constructed using Freescale's mfw_vpudecoder element on IMX53QSB evm with root file system created by LTIB tool.

When playing some videos, green screen effect with some random color noise is observed.


Example pipelines are as follows:

gst-launch playbin2 uri=file:///home/user/green2.mp4

gst-launch filesrc location=/home/user/green2.mp4 typefind=true ! aiurdemux name=dmx dmx.video_00 ! mfw_vpudecoder ! mfw_isink


Problematic media file is attached to the message.


The problem does not exist when Freescale's mfw_vpudecoder element is replaced by software-based decoder ffdec_h264.


Please give me some advise on how to resolve this problem, or, advise how to catch information about such error via GStreamer bus watch. So that I can detect hardware accelerator failure and use software-based ffdec_h264 on such occasions.


Thank you for your time.
