That would also be horribly slow for large frames. I'd suggest using a
fragment shader to perform the conversion then glReadPixels to get it
back to the CPU (or even better pass the texture id to gstreamer if it
can work with them and avoid the round trip).

No. Video formats are not supported for paint operations. You'll have
to convert.
You can use a Runnable and do it on another core, though that adds
asyncronicities...

*Subject:* [Interest] Screen Capture as format YUV
Hi everyone,
I have a project related to image processing on QT and GStream. I have
created a program with QWidget, and I got a screenshot of this program
with QPixmap. However, I need to convert these frames into a YUV
format and send them to GStream because I am going to merge these
frames another video frames with GStream.
Is there any way I can get QWidget frames in YUV format? Without
conversion. I am working on QT 5.5. Any advice ?
Thanks,
Emre Cetin
