[jitsi-dev] JAWTRender issues on mac (white video player)


#1

Hello,

We are having some problems with mac video rendering.

Video is working perfectly for windows clients but on OSX (tested with
10.8.5) we have only white (blank) video players and all videos are
displayed in the lower left corner (overlayed).

It seems that JAWTRenderer doesn´t respect the VideoComponent coordinates in
the java window and paints all videos to the same „erroneous“ coordinates.

Please see attached screenshot.

Cheers, René

Have you modified the VideoLayout.java in any way? It is the one responsible for laying out videos in the VideoContainer.

Cheers,
Yana

Hi Yana,

No, I didn´t change VideoLayout.java.
Also the video is displayed correctly on windows.

Hey Rene,

Lyubo and Damian just reminded me offlist that this was a problem that looks like what we are seeing with Java 1.7.

Is that what you are using? If so, can you try with Java 1.6?

Hi @ll,

Unfortunately this is not possible as there exists an evil java web start
bug in the jvm implementation which also seems to affect apple´s java 1.6
plugin:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8019274

As our app is based on java web start, so I have to run with 1.7.21 for the
moment until this bug is fixed.
(Apple also introduced this bug in one of the last plugins and it seems that
you can´t downgrade to an old version of the apple´s plugin).

I could "successfully" reproduce the video bug on another iMac running OSX
10.8.4 and Oracle Java 1.7.21. The videos are painted outside of the
VideoComponent and the VideoComponent stays white.
I think I will try to debug the JAWTRenderer a little bit.

Can you please give me a hint about how to setup a build environment on OSX?
Do you use XCode on Mac? The README in the JAWTRenderer folder only mentions
Windows OS.

Cheers, René

Hi Emil,

Right now I could test with an Apple java 1.6.0_65 (pre-installed on a new
iMac) without Oracle java installed and the problem is almost the same.
The video component stays white and the whole application get's really
sticky when video component is painted.
Also there is no video painted in the lower left corner as with java 1.7.

I'll continue testing and will provide feedback.

Strange this sounds exactly as if you are running it with 1.6

Also there is no video painted in the lower left corner as with java 1.7.

I'll continue testing and will provide feedback.

You could try it out with a multiparty video call using jitsi with a
jit.si account or one from ippi.com
