Camera pipelines

[Nagendra, Gururaj]

As gst's CameraBin implementation evolves, is there convergence to move towards improving it in the near term to take CameraBin out of the ugly plugin category and make it the default implementation for still and video preview+capture and may be even for video conferencing apps? More camera apps should then start using CameraBin so the application and gst will pretty much become a standard. There could be optional elements for certain post processing, but the pipeline should be standard.

There are different ways of implementing the preview and capture pipelines depending on the underlying hardware implementations out there today. Hence having standard pipelines for key use cases will enable targeting the underlying integration with V4L2 and other user/kernel level components. Today, I don't think this is the case. I'd appreciate if experts here can comment.

Thanks,

CameraBin is really meant for capture to disk, it is not really
appropriate for video conferencing applications. For those cases, you
probably want to look at Farsight instead (which could also have been
called CallBin).

That said, I fully agree that "Simple video capture" apps should
converge around camerabin.

Its for sure the goal to get it to good and thus the recommended way for capture
apps. Currently its still quite much under development and it would be good to
have more apps using it before agreeing on the api and declaring it stable.
