GNOME Bugzilla – Bug 794339
Add DRI3/Present extension support in ximagesink, glimagesink, etc.
Last modified: 2018-11-03 12:04:05 UTC
DRI3 has an extension which allows to convert DRM_PRIME_BUFFER to Pixmap and present it on the screen using "Present" extension.
This could help to do zero-copy pipelines like
VAAPI_decdoe ! ximagesink
MediaSDK_decode ! ximagesink
