MFX_ERR_UNDEFINED_BEHAVIOR after update of graphics driver.

Hi,

I encode the same stream in a cycle. Each time I call MFXVideoENCODE_Init and MFXVideoENCODE_Close. I use auto selection of any hardware implementation (MFX_IMPL_HARDWARE_ANY).

Stream info:
width = 320
height = 240
FourCC = YV12
56 frames

For example:

int total_frame_cnt = 0; //total count of encoded frames
while(1)
{
MFXVideoENCODE_Init();
Encode 56 frames...
total_frame_cnt += 56;
MFXVideoENCODE_Close();
}

After update of Processor Graphics 2000 to version 8.15.10.2696 MFXVideoENCODE_Init returns MFX_ERR_UNDEFINED_BEHAVIOR when total_frame_cnt = 114632.

Hi Marina,

this has been confirmed to be an issue when using an HW accelerated session. We will work to get this resolved as soon as possible.

As a workaround you can instead close the session and create a new one for each encoding workload.

Regards,
Petter
