Hello all,
In order to improve and add missing features in the DirectShow Qt Multimedia
backend, I’d like to include a third-party library in Qt, namely, the
DirectShow Base Classes Library [1]. See link [2] for the patch adding it in Qt
Multimedia.
I’m just not sure about the legal part. This

?The gst-0.10 backend is not going away, we'll still have it along gst-1.0. It
was decided to do a soft release for the gst-1.0 port. In Qt 5.5, gst-0.10 will
still be used by default, Qt will have to be configured with some option to
enable gst-1.0. It will then become the default backend in Qt
There is no API in Qt Multimedia to do this. As mentioned, QMediaRecorder can
only be used with a QCamera.
In a similar fashion to QAudioDecoder, we could have APIs like QAudioEncoder,
QVideoDecoder and QVideoEncoder. Though, considering the amount of work there
is to improve existing APIs, I d

Ongoing porting effort is happening in the 'wip/gstreamer-1.0' branch.
It most likely won't make it into Qt before 5.4.

Hi,
No you can't do that using the Qt API only. The only way would be to create a
custom QAbstractVideoSurface (to set on QCamera) from where you would get the
video frames and would be able to process them. Then the problem is that you
can't use QMediaRecorder to save to a file, you would have

Compiling wouldn't be the problem. A few implementation details can work only

Hi,
There is an issue in 5.1 when starting a video immediately on app startup.
Could you try to delay the loading and starting of the video, on mouse click
for example, and see if the problem is still there?
If you compile the wip/android branch, make sure to remove the 5.1 multimedia
