[Libva] vaPutSurface threading issue

[Sambhav]

Hi,

In my application there are two threads.
 Thread 1: Does decoding
 Thread 2: Does display (i.e. vaPutSurface)

With X-Server 1.6.X the application crashes and exits with following error

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server
":0.0"
      after 54 requests (53 known processed) with 0 events remaining.

However if I make the application run in same thread it works fine.


The same 2 threaded application worked fine with X-Server 1.4

Is this kind of 2 threaded operation permitted ?
Can anyone tell me why this error occurs and solution if any ?

Regards,
Sambhav
