What about hrev51306?

comment:2 by diver, 3 years ago

CPU usage is still high. Can't trigger the crash tho.

comment:3 by korli, 3 years ago seems to also be affected. MediaPlayer (or something it calls) seems to insist on extracting video frames which are not present.

Note that the the slider of the progress bar never moves while playing that ogg sample clip. I also see that problem with one of my m2ts trailers.

High CPU usage fixed in hrev52358; however, the time indicator still does not increment on these files.

Still getting high CPU usage on some files here. In media player, "event queue runner", "playback manager", "media extractor thread" and "frame generator" threads are busy, as well as the main window thread.

How did we end up with so many threads just to play a media file anyway?

Probably more of a MediaPlayer bug than Media Kit, though I don't know for sure yet. Probably the same issue as #15220.

Note: See TracTickets for help on using tickets.
