<div dir="ltr">As per my understanding the pipeline you are created is not correct(found on url: : <a href="http://pastebin.com/KL641ULY" target="_blank">http://pastebin.com/KL641ULY</a>). even output from 2 fake device will not work(to confirm use different pattern type for each videotestsrc) use videomixer, so you can have two videos side by side in single video file. or use two filesink to capture the video in two different files. </div><div class="gmail_extra"> <div class="gmail_quote">On Mon, Jan 19, 2015 at 4:25 PM, Thiago Santos <<a href="mailto:thiagoss@osg.samsung.com" target="_blank">thiagoss@osg.samsung.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 01/17/2015 05:12 AM, Briner Cédric wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello, I'm having trouble to record two streams simultaneously in a single container.
