testsrcbin

This is a simple GstBin source that wraps audiotestsrc/videotestsrc following specification passed in the URI (it implements the GstURIHandler interface) in the form of testbin://audio+video or setting the "stream-types" property with the same format.

This element also provides GstStream and GstStreamCollection and thus the element is useful for testing the new playbin3 infrastructure.

Example pipeline:

gst-launch-1.0 playbin uri=testbin://audio,volume=0.5+video,pattern=white
