Reliance on CUDA for FFMPeg Hardware encoding causes codec warnings with AMD GPUs #4764

Open jeremymeyers opened 7 months ago

jeremymeyers commented 7 months ago

Describe the bug Stash appears to call on CUDA for hardware-level decoding. CUDA is a library specific to NVidia GPUs, called in the FFMPeg init https://github.com/stashapp/stash/blob/911da8726415a728f5c8fa8455ddca9259fa772e/pkg/ffmpeg/codec_hardware.go#L120and seemingly connected to support for some VP9 and h264 codecs.

I haven't been able to test whether it breaks vp9 playback as i don't seem to have vp9 files in my library but thought it was worth mentioning.

There are apparently multiple options when it comes to FFMpeg hardware encoding, as detailed here https://trac.ffmpeg.org/wiki/HWAccelIntro and NVENC(of which CUDA is a part) is very limited in its compatibility relative to other options, only being compatible with Linux and Windows with NVidia GPUs.

To Reproduce Steps to reproduce the behavior:

  1. Have computer with AMD GPU
  2. launch stash.exe

The following errors appear:

I don't believe AMF is explicitly supported, but the presets for hwaccel are generally troublesome, there was someone in discord reporting decoder surfaces missing because NVDEC doesn't support .wmv

I think it would be better to move configuration to the user side or pick from a dropdown instead of auto-configurations, which would allow for AMF support

I would say okay if there are robust presets. Selecting hardware codec options is a really niche subject that most users are not going to be familiar with and if there a chance they could break playback by selecting the wrong thing then it should not be that open
