For still image, I think we do not need timestamp.
For view-finding, the 'sync=false' of video sink could also ignore the timestamp.
Is it right?

erm, its not as easy as that. The audiosrc is not running for still
images or viewfinder (atleast not in camerabin). Using "provide-clock"
would cause the clock to change while the pipline runs (unless we keep
the audiosrc running all the time).
