meta-qt5 on master-next does not build video mediaservices

[michaelb_]

Hello

I am pretty new to imx6 and yocto development. So, please excuse if my question is dumb or if I am doing something wrong.

I have a nitrogen6x board and tried to build a qt5 enabled image.I used the master-next branch with kernel 3.10, added the meta-qt5 branch and an image recipe that included qt5 and several apps (taken from here Integrate Qt5 into yocto sato image on Wandboard - Wandboard Wiki).

The build runs fine, everything seems to work (including qt5, hw accelerated GPU and VPU, tested with gstreamer), except: qt5 is build without any video mediaservice providers, so that I cannot use video in qt5.

Here is my /usr/lib/qt5/plugins/mediaservice folder:

libqtmedia_audioengine.so

I am wondering, if I did something stupid wrong (but I did follow the mentioned howto), or if qt5.2.1 is missing the video media service? In the wandboard image from here http://www.wandboard.org/images/downloads/yocto-1.5_qt5_wandboard_20140106.zip, which was apparently done following the same tutorial (but with QT5.1.1) the folder looks like this:

libgstaudiodecoder.so  libgstcamerabin.so  libgstmediacapture.so  libgstmediaplayer.so

Thanks a lot for any help!

Hi, was you able to play a video?

I got all the video informations at the console but the video isn't played.

Can you please show your PACKAGECONFIG set up and the qt module installed?

Thanks

Yes, for me it works nicely now. Here I posted some notes:

P.S.: I wonder why all my comments first need to be verified by a moderator.

What image are you building?

Thanks

Core-image-minimal plus custom packages

Well, I found the solution:

There has been a commit disabling gstreamer multimedia services by default (see here: https://github.com/meta-qt5/meta-qt5/commit/faad8d1df1aee67f9d1a7e9ea3c13f92d04baf8e).

In order to get the plugins built, you need to add:

PACKAGECONFIG_append_pn-qtmultimedia =" gstreamer010"

to your local.conf or your custom layer.

Unfortunately, the integration of qtmultimedia with imx6 is still very bad and not usable at all. I guess I need to look for another platform (bay trail looks promising).

As I don't seem to get any help here, can somebody maybe recommend a place where I can find some help regarding the missing gstreamer mediaservice plugins in qt5.2.1?

So, I am one step further: I did all the steps again, but this time checking out dora instead of master-netx (btw. is there a method to change the branch easily, or is it necessary to always start completely new, when switching the branch?).

Dora has qt5.1.1 and here the mediaservices for gstreamer are built. However, I had some other problems, so I ended up with using this image and copying all qt5 files from the published wandboard image to my image. This way I came to a working qt5 image.

Results are, however, that video playback is very much sloppy using the glimagesink, so this is now usable for me. :-(

One other possibility could be to use eglfs and draw the video with gstreamer to the BG while QT renders the OSD to the FG?

I am wondering if these warnings have anything to do with the gstreamer plugin not building?
