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?
