Thanks! The num-buffers parameter helps and the video stops recording, however, the command pipeline I have (included below) continues recording audio. Is there a parameter to specify audio-time as well? Ideally, a single parameter for specifying the time for both audio and video would be preferred by separate ones are OK as well. <br> <br>Also, I would hope the pipeline would terminate automatically so that it can be scripted.<br><br>gst-launch v4l2src !
