<div>Hi ,</div> <div> you can set "num-buffers" in v4l2src element , and I think number of buffers will depend on the framerate (fps) and the time duration ( in seconds) .</div> <div> </div> <div> Suppose fps is 30 frame/sec and the time duration is 30 secs then num-buffers will be 30*30 = 900 .</div> <div> </div> <div> Try this out . <br><br></div> <div class="gmail_quote">On Mon, Mar 8, 2010 at 4:32 AM, Pavel Johnson <span dir="ltr"><<a href="mailto:pavel.johnson@gmail.com">pavel.johnson@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hello,<br><br>I am new to Gstreamer so please bear with me if this has been addressed.<br><br>I am trying to record video from a webcam using the command line below and would like to specify the duration for which the video/audio needs to be recorded, i.e. the command below should terminate after say 30 sec of recording.
