Re: Gstreamer pipeline problem

Hi Chris,

> That's unfortunate as I need a pipeline which can run on many different platforms, including 'standard pc'. 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).
