Here is the test I successfully done to check that I have CUDA ffmpeg : time ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i small.ogv -acodec copy -vcodec hevc_nvenc test.mp4

[Barmallini]

Did you have symbol lookup error?

time ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i small.ogv -acodec copy -vcodec hevc_nvenc test.mp4 ffmpeg: symbol lookup error: /usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0: undefined symbol: wl_proxy_get_tag

No I don't have this error. I'm using the ffmpeg/impish,now 7:4.4-6ubuntu5 provided by ubuntu

[Niroc]

Hi, install cuda from your package manager (you said you already got this)

then run... git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git

and then cd nv-codec-headers && sudo make install && cd ..

and try to build ffmpeg again and see if that makes a difference?..

@mvvvv This should not require system ffmpeg libraries on deb packages, and that may actually cause the issue (though I don't think it should?). I would try uninstalling any ffmpeg libraries that exist; as you can see, ALVR bundles precompiled ffmpeg libraries in the deb:

trae@build01-deb11:~/ALVR$ dpkg -c build/alvr_17.0.0-dev.3+1644798406+7d2c1045.deb | grep -P 'lib.*\.so'

[mvvvv]

Ok I'll test as soon as I see the alvr_17.0.0-dev.3+1644798406+7d2c1045.deb in the repo. But do you mean you tweaked these libraries for alvr ?

[mvvvv]

I can't test right now cause I installed the stable deb which do not log the encoder used as it seems

[zmerp]

The deb package is not maintained anymore.
