Transcoding on i7 4770k & GTX 770 (docker)

[zjeffer]

I moved my jellyfin configuration from a Raspberry Pi 4 to a secondhand desktop PC I just bought. These are the specs:

• Intel i7 4770k
  
• GTX 770
  
• 16 GB RAM
  

I'm running it with the following docker-compose file:

Code:

services:
  jellyfin:
    image: linuxserver/jellyfin:latest
    container_name: jellyfin
    restart:  unless-stopped
    ports:
      - "8096:8096"
      - "8920:8920"
    networks:
      - proxy
    volumes:
      - ./data/jellyfin-config:/config
      - ./data/jellyfin-cache:/cache
      - /run/media/admin/Elements:/media
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Brussels
      - NVIDIA_VISIBLE_DEVICES=all
      - NVIDIA_DRIVER_CAPABILITIES=compute,utility
    runtime: nvidia
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: all
              capabilities: [gpu]

 
  caddy:
    image: caddy:latest
    container_name: caddy
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
      - "443:443/udp"
    networks:
      - "proxy"
    volumes:
      - ./Caddyfile:/etc/caddy/Caddyfile
      - ./data/caddy_data:/data
      - ./data/caddy_config:/config

networks:
  proxy:
    driver: bridge

If I try to play something with transcoding enabled (Nvidia NVENC), the ffmpeg logs show this, and playback stops:

Code:

[AVHWDeviceContext @ 0x605e7a2ffd00] Cannot load libcuda.so.1 
[AVHWDeviceContext @ 0x605e7a2ffd00] Could not dynamically load CUDA Device creation failed: -1. 
Failed to set value 'cuda=cu:0' for option 'init_hw_device': Operation not permitted

I took a look at the GPU matrix from Nvidia, and noticed the GTX 770 isn't even present in the list. I assume it doesn't have NVENC/NVDEC at all?

Here are my questions:

• Can I use NVENC with my GTX 770?
  
• If not, can I use the i7 4770k's integrated GPU with Intel QuickSync instead?
  
• I notice there's also VAAPI and Video4Linux2 support. Are any of these useful/compatible with my setup?
  

Thanks
