Hi yuan,shengquan,
Libva has a limited tracing function before. if more than one context
is created
in one process, then this tracing can't work and output wrong log messages.
This patch fixes this problem. Tracing is possible while multiple

Could you provide more details about this change? Which problem are your trying

I don`t see any reasonable alternatives.
Of cource you can copy frame from Surface to process context, and than copy to
screen.
But as you use intel internal gpu real memory banks are same, so you will only
have overhead for copy.

Thanks for your suggestion.
I was also thinking of the same method. Wanted to get alternative

Hi!
At least you can keep surfaces with output frames, use them when you want,
after release and reuse surfaces again for decoding.

Hi all
I want to buffer some decoded video frames(using libva) for display at a
later point of time. I need to find a suitable method for this. Can anyone
suggest a proper method for this.
Thanks and Regards

Hi!
Seems /dev/dri/renderD128 works. More over I don`t need to take care about
locking decoding in two processes.
What is difference with /dev/dri/card0 ?
