'''
|
|
This is an example of how to use Playbin, and send its output somewhere other
|
|
than local video/audio playback.
|
|
|
|
Using the 'video-sink' and 'audio-sink' properties, different ends of the Playbin
|
|
pipeline can be set.
|
|
|
|
Try experimenting with the 'DISABLE_VIDEO' and 'DISABLE_AUDIO' constants below.
|
|
When set to true, they allow the Playbin sink to be set to 'fakesink', which
|
|
stops them from playing locally.
