Problem CPU

Hello, I’m having a problem where my TV displays
‘Not enough CPU available, file cannot be converted’
What’s causing this, and what can I do to make it work?

Many thanks

This message basically means that your server is attempting to transcode the video but failing due to insufficient CPU power.

This can originate from the media not being supported (as-is) to play on your device – or playback quality restrictions being applied (e.g. because the client app has set a specific quality, you changed the playback quality; if you’re streaming remotely, bandwidth restrictions might also play a role).

Option 1: verify WHY the video is being transcoded and check if you can avoid it.

Option 2: if your server has a supported GPU/iGPU, you might try to shift to hw-accelerated transcoding (instead of solely relying on your CPU.
