[gst-devel] grabbing frames from running stream

[Andreas Lubensky]

Hello,

I want to use gstreamer to play all kinds of video sources, especially 
webcams, video files and DVDs. 
In the framework i am using, video sources get grabbed image by image in a 
loop. Currently, i am not sure how to combine that with gstreamer. My idea is 
to write a video sink that always keeps a copy of the last image. But this 
seems rather ugly...i thought there might be some way to get a snapshot of a 
running stream. That might be no problem with webcams, but i couldn't figure 
out yet how to do it with video files.
As i am new to gstreamer, i probably just need a nudge in the right 
direction...
