I've an embedded device with a physical screen resolution of 800 x 480, but
the pixels themselves are actually wider than they are high.
The entire GUI therefore appears stretched, so it looks like a 800 x 480 GUI
stretched to fill 800 x 520 screen.
How am I best to handle this, so my GUI does

In the unreleased QtSystems module in QtSystemInfo there is something

Is there a way to access the radio info (dB, SNR) or even just overall data
connection quality using Qt?
I know there is a Radio QML type, but this seems to be FM broadcast radio.

I looked into Micheal's solution and it's clever. However I would try a few things:
1. Use QImage's QImage::Format_RGB888, and use scanLine() to dump the image line by line to stdout. (Scanline is so much faster)
2. Try to paralellize it. Perhaps you have X cores, start X processes, offset each

I did something like this a long time ago in QML (Before Qt3D, QtQuick 1):
1. There is some kind of frame advance, so you set up the animations as you want, then you start the animation and render the first frame to an image. Then call frame advance and get the next frame, repeat.
2. Then use FFM

Or even better, contribute it to Qt 3D so everyone can benefit from it out of
the box. :)

Hi,
I think it's possible, although it's not an out of the box feature yet, as
Harald pointed out.
Have a look into this kind of approach:
* Implement something similar to the Scene3DItem that allows to embed Qt 3D
into a Qt Quick 2 scene
* This requires using a little bit of private (for now

Hi,
You may be able to use ffmpeg (the program not the library) via pipe as
described in the "writing section" here:
http://zulko.github.io/blog/2013/09/27/read-and-write-video-frames-in-python-using-ffmpeg/
They use Python but it should work with C++ as well, I assume. And using the

Greetings, I have used QtScript in a non-gui application before to write
plugins for the application. This was really slick and worked well. I am
working on a new application and wish again to use QtScript in a non-gui
context. I am given the impression QtScript is deprecated and it is to be

Hi Andy,
An alternative is to use the FFMPEG encoding library instead of the command
line tools. Then you can pass each frame to the video encoder as you
generate it without writing them all to disk first.
The natural way to generate the QImages would be to render to an offscreen
