Bug Report OpenCL still crashing

[z0rz]

OpenCL is still crashing for me like it did with the test builds. The stream will work for about a minute before the driver/OBS crashes (Error: Texture->Map failed: 0x887a0005 0x887a0007). Any hope for me to fix this or is it still a common problem?

I have a Sapphire Radeon HD 7870 and I've tried Catalyst 13.4 (current version) and 13.6 (beta).

Seems to be a common problem with certain GPU's/drivers. I streamed for an hour and a half with the new build using OpenCL and it was fine. I use a GTX 670 with 320.49 drivers. Nothing really can be done on OBS side since this is an issue with x264. The devs of x264 have to the ones to fix this issue.

More likely it's a problem with the video drivers / GPU if it's causing device failures.

Yeah, I was hoping the latest beta drivers would give me different results but it's more of the same. I tried underclocking and overclocking my GPU and changing some Catalyst settings, nothing helped :(

I figured it had more to do with the x264 side of things, but the fact that it works for some and not others has me wondering what the differences are that would allow some people to utilize OpenCL without issues. Could it be related to OBS settings? Other Catalyst/NVidia settings?

I'm sure this will get ironed out soon enough, but I'm still a bit curious.
