I have stolen the subject of this email from a previous post about the
Currently I am using XvPutImage to display a video stream. The video
needs to be overlayed with various items (pixmaps, text, custom
drawing). As it stands there is a lot of flickering of the overlayed
items. When this is double-buffered (using standard pixmaps) the
flickering, obviously, goes away.
I see that XVPutImage does not support writing to pixmaps, only to
windows (xf86XVEnlistPortInWindow seems to be the start of the
problem...). The system is running version 1.3.0. I have checked 1.7.1
and seen that it too doesn't support XVPutImage to pixmaps.
I have a few questions:
- has any progress been made in supporting XVPutImage with pixmaps?
- if not
- what are the alternatives for overlaying text, pixmaps etc?
- is there anyone who can provide me with some guidance to implement
the pixmap version of XVPutImage.
I appreciate any feedback.
