MediaPlayer & VideoOutput combo on Android - any working example?
-
I try to use MediaPlayer and VideoOutpu for displaying video content but no success... :-(
According to "some book example":http://qmlbook.org/ch10/index.html# it is as simple as stone axe but for some weird reasons it does not work for me. Neither on desktop - W7, 64 bits - nor Android device. I tried it with remote video file and local, too...
What file formats are supported by MediaPlayer?
There are some log examples below.
(1) local Mp4 file, Android device:

I don't know about remote file.
But I was able to show a local MP4 video on Android without any problem using VideoOutput, and from what I know you should set a full local URL path and you cannot embed video into Qt resources (qrc://)So, instead of an URL like:
qrc:/Vserv/qml/stock-footage-sailing-in-the-wind-through-the-waves-hd-sailing-boat-shot-in-full-hd-at-the-sailing-in-the.mp4
you should pass an URL like:
file://mnt/sdcard/Videos/stock-footage-sailing-in-the-wind-through-the-waves-hd-sailing-boat-shot-in-full-hd-at-the-sailing-in-the.mp4
