HD video decoding issues

@rafaello7 ,
I just tried your nano-video with a MP4 sample and MKV sample.
For small win size is ok, for HD res there are some issues, like freeze at some random time. Board is still running.

Video samples:
Some times works (HW decoding), SW (always works)

This always in SW but get almost 700% cpu and rendering is very slow, maybe 2 fps.

I am not sure is codec issues or not.

here is the log so you can check what could be the issue:
