[gst-devel] How to grab a frame from video stream using gstreamer

[Fredrik Persson]

Grabbing a frame out of a running video is non-trivial. It is a question
that comes up on this mailinglist with regular intervals, and pretty
often it leads to frustration since it requires very intricate knowledge
about gstreamer to make it work.

Search the archives, and you'll see.

I have filed an enhancement bug report about it, here:

http://bugzilla.gnome.org/show_bug.cgi?id=464630

In the comments to that bug report, Wim has provided a useful link:
