The command for this process was as follows:

dvr-scan -i "C:\Directory\video.mkv" -o "C:\Directory\video.avi" -b mog2_cuda -tc

Expected Behavior:
The video will finish being scanned and output an AVI video in the directory with the identified events and their timecodes.

Computing Environment:
Windows 11 Pro, RTX 4090 Notebook, DVR-scan 1.5.1, NVIDIA CUDA Windows Build (64-bit )

Additional Information:
This is maybe my 10th or 11th time using DVR-Scan with no problems up until this point.

[Breakthrough]

I think this error might be coming from ffmpeg when trying to decode the video. You may want to re-encode the video with ffmpeg or see if passing it through mkvmerge fixes the issue.
