Using idintity plugin to tap images from a gstreamer pipeling into program

[tiko]

Dear dev's,

given a program "myApp" and any pipeline "someSrc ! identity name=xyz !
filesink location=anyfile.mp4".
I want to call my program such, that I can tap the images from the
pipeline given the identity name "xyz":
./myApp --pipeline="someSrc ! identity name=xyz ! filesink
location=anyfile.mp4"

I have an example for gstreamer0.10, but porting it to gstreamer1.0
seems not trivial to me.
Does anyone of you know a good starting example, so that I can go on
with my task?

Greetings,
Timo

Nothing really changed there between 0.10 and 1.x in that regard. What
problems do you run into when porting?

Hi Sebastian,

actually, it is the error described in this Post.
We managed by using the appsink plugin which is way more straight-forward to use.
But I still wonder why my proposed port does not work (s.t. running out of memory after a while).
