Using Hardware decoder in Mac for streaming.

[Ignas Brašiškis]

1) I have no idea why this plugin is not available: I have no mac.
2) Usually software decoding is handled by ffdec_h264 or avdec_h264.
try:
gst-inspect | grep h264
It will list all built plugins.

Autovideosrc is risky: v4l2src is better choise.
