 m1cr0man | It seems that steam's video sharing depends on libcuda?

The first one is when trying to share a clip with a steam friend directly. The last one comes when exporting a clip.

 Sandro 🐧 | probably hardware acceleration in general and through that on your graphics card like nvidia which uses cuda | 00:16:40 |
| m1cr0man | Yeah some quick googling suggests that libav will try to load libcuda on startup regardless of your GPU. I have an AMD so I was particularly confused | 00:17:12 |
| m1cr0man | The exporter literally fails though, as you can see there. Kinda annoying. | 00:17:30 |
| m1cr0man | This can probably be fixed with override + extraLibraries, but the second one I'm not sure about. Is that to do with the steam FHS vs the /run directory having non-FHS/nixos native libs? | 00:18:55 |
| Sandro 🐧 | Do you have 32-bit mesa drivers? | 00:40:09 |
| Sandro 🐧 | it probably tries to load and find out what the right library is | 00:40:38 |
| Sandro 🐧 | that bit is .. complicated | 00:41:05 |
| Sandro 🐧 | pretty complicated | 00:41:08 |
| Sandro 🐧 | we have nested cgroups/fhs there | 00:41:16 |
| m1cr0man | In reply to @sandro:supersandro.de
Do you have 32-bit mesa drivers? I think I do? I'll have a check today | 10:12:02 |
