Hi,

I getting this error 

intel_do_flush_locked failed: No such file or directory

when I try to use GLX to render the decoded surface. Anyone knows what could be happening?

Thanks!

Hi Fernando, 

Need more information to look into this like Processor configuration, graphics device, driver version, OS. What product do you have - Media Server Studio or INDE and which version?
Are you using sample_decode from the samples package, can you please give us your cmd line. 
Please send us the above requested info to look into the issue.

Thanks,
Surbhi

Hi Surbhi,

processor: i3-4010U

GPU: Intel Haswell-ULT Integrated Graphics Controller

SO: CentOS

Driver: Using Media server R4 and R6

sample_decode is working without problems (that sample is using X11 for rendering). No problems with x11 rendering.

The problem appears when I want to use openGL for rendering using VA-API using GLX.

Thanks.

Hi Fernando, 

Media Server Studio is more focused on headless/datacenter use case. So we do show rendering can be done using x11 samples but they are not fully optimized, because of the focus being on headless use case. This question is out of Media Server Studio scope. But there is another Intel forum more focused on graphics which might be a better place to get answer for OpenGL related queries - https://software.intel.com/en-us/forums/developing-games-and-graphics-on-intel .However, while looking for this error, I do find few solutions online. You might want to do quick search with the error and pipeline description. 

Thanks,
Surbhi
