I have /lib/firmware/vpu/vpu_fw_imxq6.bin, size 253968, the last 6 digits of md5sum is e8debf.

I tried these:

1. http://www.webmfiles.org/demo-files/
The webm examples play nicely, even scaled to full screen.

2. http://devfiles.myopera.com/articles/1891/custom-controls-webm-720p.html
It's the same "Elephants Dream" as one of the examples in (1) but at 720p.
It pays nicely in the browser control but it's a slideshow as full screen.

On the other hand, gstreamer 0.10 with gst-fsl-plugin and its gst-fsl-plugin-gplay
subpackage, gplay plays a 720p and a 1080p H.264 test file very well without tearing.

Best regards,
