Common Issues

Missing Hardware Acceleration Options

The hardware acceleration options listed in the FFMPEG Settings page are derived from output generated by the your configured ffmpeg executable. The command used to discover available hardware accel. options is

ffmpeg -hide_banner -hwaccels

There are a few reasons why your desired hardware acceleration option is not appearing in this list. Here a few of the common ones we've seen:

1. If using Docker, you are not using the appropriate image tag. For instance, if you want to use Nvidia hardware accel, you must be sure to use the *-nvidia labeled Tunarr builds. For iGPUs, like Intel GPUs, the *-vaapi Docker images are required.
2. The ffmpeg executable used by Tunarr is not correct. Double-check the executable path configured by Tunarr with the one in your CLI environment (which ffmpeg). One example of this running on Ubuntu and having installed a version of ffmpeg with snap (executable in /snap/bin/ffmpeg) and one with apt (in /usr/bin/ffmpeg).
3. The ffmpeg executable you are using does not have the necessary libraries compiled in. This can be verified with the hardware accel. command above.

If you've double-checked these things and still are experiencing issues, please open up a new Q&A discussion topic so we can debug.
