This was one reason why I was using fakesink to capture the images - v4l looked like a way to go so that I could stream the video direct to the screen and get the full benefits of any acceleration supported by a platform (zero copy, etc.). > I think you will probably need to build an application that creates a pipeline based on the host. For example, a desktop system probably will not have much use for V4L output devices, so they might not use v4l2sink but autovideosink. On a i.MX6 for example, you'll want to use mfw_v4lsink, which as I understand it does take advantage of some of the built-in acceleration. Also, for video decoding (H.264 decompression I mean), you'll want to change the element you use there as well. For i.MX6 this is vpudec, but for general purpose there is x264dec (think that is the name but not sure). Regards, John
