Just to say that I've had some success in displaying videos with
cgkit.mediafile, thanks to
https://github.com/hmeine/qimage2ndarray. I didn't succeed at
installing/compiling it from source myself, but thanks to the work
of Christoph Gohlke, there are Windows installers for Python2.6
through 3.3 available at
http://www.lfd.uci.edu/~gohlke/pythonlibs/#qimage2ndarray. I had
to back off from using PyQt4.10 to PyQt4.9, but that was a small
price to pay for success! Instead of my failed attempts to load a
QImage from a QByteArray (below), I can do the following now:
Just to add that in my case I also had to flip and rotate the array 90 degrees for it to display correctly; otherwise it was sideways and reversed.
Video display solved; now if I can only figure out how to play the audio stream ...

[...] # convert ndArray into a QByteArray NOTE: is this correct ??? byteArray = QByteArray(ndArray.data.tobytes()) img.fromData(byteArray)I have never tried passing an image from mediafile to PyQt, so I can't give you a working example, but I believe the above fromData() call expects an encoded image file, not the raw image data. So you could use it if you had a jpg image, for example, but for passing raw data, you would have to use one of the constructors that take a raw data pointer (at least if you were using C++). I'm not sure if/how that is exposed in Python though. Cheers, - Matthias -
