Choppy prores 4k playback
Locked
 
|
I'm trying to play a 4K prores video with gst-play and the playback is very
slow, around 1-3 fps. The same video on the same computer (which is a pretty hefty xeon thing) with mplayer plays just fine with no visible frame drop. Now, this is very strange to me because afaik I'm using avdec_prores which means that both gstreamer and mplayer are, in fact, using the same codec. -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

I'd suggest to describe a bit more what you are doing. In general, a bad display sink match can cause this.

I would recommend turning the sync=false on your display element. This will prevent the player from attempting to sync on the clock which, especially at 4K, can result in a lot of dropped frames. This is what I do for 4K. On Mon, Jul 1, 2019 at 10:22 AM Nicolas Dufresne <[hidden email]> wrote:

You system is probably not fast enough to reach full frame rate, and then combine with another plausible bug (multiqueue higher limit might be too low for 4K with slower then real-time decoder). Another option would be to increase processing-deadline property on your display sink. > > > skyline220 wrote > > I would recommend turning the sync=false on your display element.
