CUDA_ERROR_UNKNOWN Transcoding errors for EU orchestrators

Nobody has claimed this yet.

It doesn't seem to drop the stream itself, and only seems to happen for EU orchestrators (https://discord.com/channels/423160867534929930/932724294230900776/962928882665783306)

**To Reproduce**
Have an active Orchestrator in the EU region

**Expected behavior**
To transcode the segments without error

**Desktop:**
- OS: Arch Linux (Also on Ubuntu 20)
- Livepeer 0.5.29
- Driver Version: 510.60.02
- CUDA Version: 11.6

Start with the reported errors in decoder.c:64, transcoder.c:236, and the callers logged from ot_rpc.go:140 and ffmpeg.go:609. Compare transcoding behavior for EU orchestrators under the stated OS, driver, and CUDA versions, then verify that segments transcode without CUDA_ERROR_UNKNOWN.
