[gst-devel] possibility to add another source pad to v4l2src

[Kapil Agrawal]

Hello,

If I am right there is only one srcpad that can be created by elements using
pushsrc baseclass. There could be 2 ways of having 2 srcpads,
1) Create a Capture bin with 2 v4l2src elements (Better option)
2) Rewrite the v4l2src element to not use pushsrc (not suggested)

Not sure if there are more options.

Regards
kapil
