HEVC fallback broken for Intel iGPU #2

Open Jefferson-tan opened 5 months ago

Jefferson-tan commented 5 months ago

Transcoding with hevc on systems with hybrid graphics (Nvida + Intel iGPU) seems to be broken ATM, seems like it's still trying to use Nvidia even though it should fallback to using Intel after failing the first time.

Saying "yes" spits out this exit code instead

Oh no! Nvidia transcoding failed! Do you want to try again with Intel QSV? yes
