Hi, I am facing performance issue while using glimagesink as video-sink. A lot of frames are being dropped and video is showing 1 frame almost per second. But while using using autovideosink, no frame drops observed and playback is very smooth. 
log is attached. ("*:3,glupload*:4,gstbasesink*:5")

Please let me know if you need more info.

Thanks

Is autovideosink using glimagesink, or the Direct3D one?

Also, 1fps usually means the frames are arriving late to the sink

autovideosink is using Direct3D.

The only difference in both pipeline is autovideosink and glimagesink.
glimagesink internally use glupload, glcolorbalance etc... so I can't say exactly which element is causing frame delay. But one thing I m sure is something wrong in glimagesinkbin Bin element.

Pleaase let me know if you need more info or logs..

Some pipeline graphs would be useful to know what you're attempting to run.

Some GST_DEBUG=3,gl*:5,*base*:5 logs might also be useful.
