[gst-devel] Simple example of a video filter

[Brian Michalk]

I've been looking through the sources for a simple element that I can 
use as a basis for a filter that I want to write.
I don't have much experience in video streams, so I'm intimidated at all 
of the plumbing needed to implement a lot of the functions of a normal 
element.  Functions like seeking, resetting, etc.  I've looked at the 
Pango text overlay, and the Theora encoder, as well as a few others.  
When I get into the video chains and such, I get lost in the amount of 
detail.

I have also created a new node with the boilerplate, and compiled it, 
and verified that it runs in the pipeline, but then am lost in finding a 
good example on how to get from there to modification of the video stream.

I would like to start simple.  Not so simple from boilerplate, and not 
so complicated as the two I mentioned above.  I figure a good start 
would be to modify a video stream.  For an I420 stream, I want to 
increment each pixel of the Y plane.  Once I get to that point, I know I 
can get the rest of the filter implemented.

Is there any documentation, or simple app notes closer to what I am 
looking for?
