Usually whenever I have scrolling (digital) video it's because the height, width, or gap between frames is slightly off. However if it's analog video it could be some other issue, like not using the correct mode or some other funny timing issue. -Josh <div class="gmail_quote">On Thu, Jul 7, 2011 at 5:22 PM, William Metcalf <<a href="mailto:wmetcalf@niftytv.com">wmetcalf@niftytv.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"> I have an application in C which uses the DeckLink API to capture video from my Intensity Pro capture card. I take each video frame and put it into a queue, and then I push that queue to a gstreamer pipeline using the appsrc element. I take each of these raw frames from the pipeline and write them to a file. Whenever I try to play this file I get the video that I have captured from the cards, except that it is continually scrolling vertically on the screen. I am almost sure that I have my parameters right because the picture is perfect except for it scrolling vertically. I am not sure if this is specifically a gstreamer question, but has anybody else ever run into a problem like this or know what could be causing this problem?
