When the drm video output is used under VT with a terminal multiplexer like screen, the VT_SETMODE ioctl call will fail since the controlling terminal is a pseudoterminal instead of a real one, thus the VT switcher will be unavailable. The problem is, the wait_events function inside vo_drm.c will test for this, and will do nothing if the switcher is not active. Normally, this would not be noticed, however, when you pause a video, or if you're playing multiple image files, mpv will suddenly start busy waiting on a single core. I confirmed this by building mpv with gprof support, in a few seconds, wait_events got called about 90 million times. So I added a fallback, when the VT switcher is not availble, just use the vo_wait_default function. I tested it and it's working well so far. |
