<div dir="ltr">You need to provide more information. What is your host OS? Do you have guest services installed? Can you access the camera or other USB devices from Ubuntu? Have you left anything out of your pipeline? For the v4l2src element you should specify the device location ("/dev/video0" is the default) and maybe the video standard (I am not sure about that). If this doesn't help then enter 'export GST_DEBUG=*:5' and then re-run your pipeline. You will get tons of debugging messages. You should be able to find the problem. If not, post the output here and someone will help you.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 10, 2015 at 5:33 PM, doon <span dir="ltr"><<a href="mailto:don-prog@mail.ru" target="_blank">don-prog@mail.ru</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have Ubuntu(guest OS) on my VirtualBox and I trying to playback video which<br>
