From [@lars18th](https://github.com/keylase/nvidia-patch/issues/491) and [@reloxx13](https://github.com/keylase/nvidia-patch/issues/544#issuecomment-1170310363)
Here a simple command to check if the patching works:
### Linux
```
ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda \
-f lavfi -i testsrc -t 50 \
@ -12,6 +12,19 @@ ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda \
This only requires to have installed a recent ffmpeg version compiled with nvenc enabled. Almost all distributions have it now.
### Windows
ffmpeg download https://www.gyan.dev/ffmpeg/builds/ffmpeg-git-full.7z
```
ffmpeg.exe -y -hwaccel cuda -hwaccel_output_format cuda ^
-f lavfi -i testsrc -t 50 ^
-vf hwupload -fps_mode passthrough -c:a copy -c:v h264_nvenc -b:v 4M -f null - ^

```
## Output
If you get a message like:
```
[h264_nvenc @ 0x55fc31535fc0] OpenEncodeSessionEx failed: out of memory (10): (no details)

```
Then... Congratulations! The patch works.
