@ -247,6 +250,22 @@ Essentially all you need to do during build is:
`docker-entrypoint.sh` script does on-the-fly patching by means of manipulating dynamic linker to workaround read-only mount of Nvidia runtime. Finally it passes original docker command to shell, like if entrypoint was not restricted by `ENTRYPOINT` directive. So `docker run --runtime=nvidia -it mycontainer echo 123` will print `123`. Also it can be just invoked from your entrypoint script, if you have any.
## Flatpak support
If you use a Flatpak app that uses NVENC/NvFBC (e.g. OBS Studio, Kdenlive), it's recommended that you patch the NVIDIA drivers for Flatpak as well. To do so, just pass the `-f` parameter to either `patch.sh` or `patch-fbc.sh`, like so:
```bash
bash ./patch.sh -f
bash ./patch-fbc.sh -f
```
In case something goes wrong, you can restore the original Flatpak drivers by adding the `-r` paramater:
```
bash ./patch.sh -f -r
bash ./patch-fbc.sh -f -r
```
## Benchmarks
* [Plex Media Server: nVidia Hardware Transcoding Calculator for Plex Estimates](https://www.elpamsoft.com/?p=Plex-Hardware-Transcoding) - useful benchmark of achieved simultaneous transcodes with various stream quality and hardware with patched drivers.
