The header you need is in the stretch package [1], good luck! Are you building

Hi,
We have an application that use Qt and GStreamer to display a live camera feed
into a widget. The view work fine when inside the Window manager and maximize.
I get some glitch and refresh lag when I put the application into full screen.
I was wondering what is the difference when we do the f
I would be very interested in such a solution as well, but I don't know anything about "fragment shaders". If you know of any resources, I'm all ears!

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...

Hi,
Out of curiosity, how feasible would it be to deploy a more up-to-date
QtWebEngine on a system that's stuck on an older Qt version. I understood from
a previous exchange that QWE is much more a "thin wrapper" around the actual
web engine than QtWebKit is, with the intention of making it eas

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 anoth

Pin debian testing repos with a low priority in the apt configuration and
you can get the binaries from there. Current it 5.11.2.
