Dear Community

The recording on my CA is working pretty fine: VGA grab, DV camera and
ALSA audio everything ok. But when I watch the video it is lagging: The
first three seconds look good, like a fluid film should looking like.
After this time, the video is frozen, then it follows a short fluid
phase again ... and so on. The same with the VGA grab video. The audio
file is ok, it has constant speed.

The CA has an 2.2 Ghz CPU and 8 GB RAM, but in the install-script I
allowed only 2 GB for matterhorn to use. Where can I increment the
memory use for matterhorn?

Here are my device specifications of the CA config file (I set the
buffer size quite high, I hoped it will help but it didn't):

# name definition??
capture.device.names=ALSA,DV_1394,VGA

#Create the screen capture
capture.device.VGA.type=EPIPHAN_VGA2USB
capture.device.VGA.flavor=presentation/source
capture.device.VGA.outputfile=VGA.mpg
capture.device.VGA.src=/dev/video0
capture.device.VGA.framerate=15

#create dv_capture
capture.device.DV_1394.type=DV_1394
capture.device.DV_1394.outputfile=dv_1394.mpg
capture.device.DV_1394.flavor=presenter/source
capture.device.DV_1394.src=/dev/video0
capture.device.DV_1394.codec=ffenc_mpeg2video
capture.device.DV_1394.codec.bitrate=2000000
capture.device.DV_1394.framerate=25
capture.device.DV_1394.buffer.size=1000

#Create the audio capture
capture.device.ALSA.type=ALSASRC
capture.device.ALSA.flavor=presenter/source
capture.device.ALSA.outputfile=Alsa.mp3

Do you have any recommendations for a good/working device specification
to solve my "lagging" problem?

Thanks for your answers
stefan
