I used OBS for IP cam streaming for about a year without any problems. Recently it stopped working. When I start OBS, it comes with a blank screen. I tried transform and fit to screen but it didn't help. In the below log, you see "glGetIntegerv(GL_MAX_TEXTURE_ANISOTROPY_MAX) failed", I was having that warnings, when I was able to stream as well. So, I dont believe it causes the issue. Can you please give me a hand to fix this.

Hi Selim, I have a black screen within OBS too. Like you, I have not had any replies to my question. Can you tell me how I use a VLC source?
Thanks
