I tried to increase webcam quality, but while I change resolution to
640x480,
I still see the webcam picture very pixellated, like if it was a 320x240
video.

I followed the FAQ to increase quality, but I don't see improvement:
http://code.google.com/p/bigbluebutton/wiki/FAQ#How_do_I_change_the_v...

                <module name="VideoconfModule"
url="VideoconfModule.swf?v=4005"
                        uri="rtmp://bigbluebutton.moodle.duf.hu/video"
                        dependson = "ViewersModule"
                        videoQuality = "100"
                        presenterShareOnly = "false"
                        resolutions = "640x480,320x240"
                        autoStart = "false"
                        showButton = "true"
                        showCloseButton = "true"
                        publishWindowVisible = "true"
                        viewerWindowMaxed = "false"
                        viewerWindowLocation = "top"
                        camKeyFrameInterval = "30"
                        camModeFps = "25"
                        camQualityBandwidth = "0"
                        camQualityPicture = "90"
                        enableH264 = "false"
                        h264Level = "2.1"
                        h264Profile = "main"
                />

Any idea?

Hi Klor,

We've updated the documentation at

http://code.google.com/p/bigbluebutton/wiki/FAQ#How_do_I_change_the_v...
?

In BigBlueButton 0.80, to modify the quality of the picture,
change camQualityPicture.

Try increasing the value slightly -- you may notice a small improvement in
picture quality as you get closer to 100 percent.  There is a tradeoff in
frame rate; however, as the higher the bandwidth, the lower frame rate
you'll see.

We have the default set at 90 percent as it seems the best trade off
between quality and frame rate.

Regards,... Fred

Thanks for the FAQ update!

However, while I changed
camQualityPicture="100"
the quality is still bad, it is pixellated.

I have this setting currently:
                <module name="VideoconfModule" url="VideoconfModule.swf?v=4005"
                        dependson = "ViewersModule"
                        videoQuality = "100"
                        presenterShareOnly = "true"
                        resolutions = "640x480,320x240"
                        autoStart = "false"
                        showButton = "true"
                        showCloseButton = "true"
                        publishWindowVisible = "true"
                        viewerWindowMaxed = "false"
                        viewerWindowLocation = "top"
                        camKeyFrameInterval = "30"
                        camModeFps = "25"
                        camQualityBandwidth = "0"
                        camQualityPicture = "100"
                        enableH264 = "false"
                        h264Level = "2.1"
                        h264Profile = "main"
                />

Should I use enableH264 option?
Would it result any quality increase?

Thanks,
Konrad

Hi Konrad,

There is no built-in h.264 option in BigBlueButton 0.80 (the parameters
were there for internal testing).  We're investigating enabling h.264 for
0.81, which were working towards a beta.

You'll see a notice posted in bigbluebutton-dev when we have a beta of 0.81.

Regards,... Fred

Konrad,  if your still seeing pixels at 640x480 i would check to see
if you webcam supports... A lot of low end laptaps have relatively low
res web cams...  I use an external USB Logitech 9000 camera that does
HD to get best results.

Stephen

My webcam supports even higher resolution, than 640x480.
The reason why I use in this resolution, that it supports 640x480 at 30 fps.

While under Ubuntu 10.04 in local players /dev/video0 has crystal clear picture,
when it comes to stream in BBB, it becomes pixellated, even when
camQualityPicture = "100".

I have no idea.

Should I restart bbb at each client config change?
As I have seens, it doesn't need.

Thanks,
      Konrad Lorinczi

dont need to restart bbb server when you just make changes to
config.xml..

I've not used ubuntu desktop at all...  I know on win 7 everything
works fine with HD cameras in general.

May be specifc to video drivers, thats where i would look.

regards,
Stephen
