<html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> I am trying to record video. The recording time can be over an hour and if I try to record to a single file, the file can get too large. I wrote a script to attempt to record a series of shorter videos - and then use Ctrl-C to stop recording when I wanted to finish. Below is a simplified version of the script. #!/bin/bash fileNamePart="${HOME}/video" v4l2-ctl -i 1 counter=0 while [ $counter -lt 100 ]; do let counter=counter+1 fullFileName="${fileNamePart}-${counter}.avi" `gst-launch-1.0 v4l2src norm=PAL num-buffers=100 ! 'video/x-raw,format=(string)I420,width=352,height=288,framerate=(fraction)25/1' ! queue ! mux. alsasrc num-buffers=440 ! audioconvert ! 'audio/x-raw,rate=44100,channels=2' ! queue ! mux. avimux name=mux ! filesink location="$fullFileName"` Note that this test version has the num-buffers set to 100 for the video source. When I run this script for a short while, I get the following on the console [ian@localhost ~]$ ./testScript Video input set to 1 (Composite1: ok) ./testScript: line 8: Setting: command not found ./testScript: line 8: Setting: command not found ^C [ian@localhost ~]$ The first video records without any comment, the second and subsequent attempts get that 'Setting: command not found' message. The final video - the one that is terminated by the Ctrl-C - does not seem to have recorded the video properly. When I try to view the videos, that final video does not display the actual material, just a 'filmstrip'. If I carry the videos from my Linux box to a Windows machine, editors fail to open the final AVI file. Thus far, two questions. 1) What is the meaning of that 'command not found'? 2) Why does the final video, terminated by Ctrl-C not work? I then noticed that I have num-buffers on both the video and audio sources - so I removed the 'num-buffers=440' - but now the first video did not come to a natural end but waited until the Ctrl-C. Third question. Do I need to have num-buffers on both sources? Your help is appreciated.
