1296152 - Don't use all CPUs to decode high resolution videos

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect)

Description

[Jean-Yves Avenard [:jya]]

The FFmpeg decoder is configured to use all CPUs available when decoding videos.

This doesn't let much time left to do anything.

We should leave one CPU free to do the other tasks.

Too late for 49 but do we want to uplift that in 50?
