Hi

I am able to stream to Twitch (albeit very poorly due to my internet), but I cannot record locally.

I have done a lot of searching and it appears that this is a rare issue.

I am running a laptop with a Nvidia Graphics Card.

Relevant Log attached.

Do you have Shadowplay installed? Is it running?

My understanding is that Nvidia cards have a limited number of NVENC sessions that can be running. If that number on this card is "1" then it's possible that your card has NVENC support (which it seems to me that it does, and it says so in the log) but OBS cannot access a session when it tries to record, and produces the " Failed to open NVENC codec: Function not implemented" error.

A quick search turns up this:

Perhaps OBS is running on adapter #1?
