Looking for multi-pads source element
 
|
Hi
The basesrc only have one pad. I want to add another static pads to basesrc.
Is there any source element which have more than one pads? I am looking for such element for reference.
Thanks.
Best Regards!
Hu Gang

A tee (http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-tee.html) doesn't resolve your problem? i think sources usually have only one pad because it is pretty easy to copy the source data to multiple streams using the tee element. Don't know if your case is different, hope this helps you. best regards, Katcipis

Maybe we could discuss and get this working together? I've been wondering if it would be good to inherit from GstBaseSrc or GstPushSrc and add more pads to it.

En, I am writing the source element for camerabin2. We can work together
in the future. My currently plan is writing a GstCamBaseSrc inherited from GstElement. But I think the most of the code should be same as the GstBaseSrc. I also need to refer other element to know how to manage the pads. The camera source element inherits from GstCamBaseSrc. I will send out the first design later.

I once started copying code from basesrc, but it becomes quite a copy'n'paste session :/ At some point in one of my other lives I plan to look at this again.
