Should sync=false, async=false be set in case of live sources ?

[Manoj]

Hi,

Searched a lot on web but still have confusion regarding 'sync=false,
async=false' in case of live and non-live sources.

If i am not wrong, when using NON-LIVE sources like filesrc, GstBaseSink
will synchronise on the clock and hence we need to have 'sync=true' (if not
specified it is default set to true) 
And hence all the clock waiting/dropping will be handled in GstBaseSink
during rendering as mentioned at,
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-libs/html/GstBaseSink.html#GstBaseSink--sync


However, when using LIVE sources like udpsrc, source element will become the
clock provider. If demuxer in pipeline, it will become the clock provider
and hence take care to output the demuxed buffers as per their timestamps.

So confusion is, should we explicitly set 'sync=FALSE async=FALSE' in this
case ? To avoid double timestamp checking in GstBaseSink ?


Please suggest if any gstreamer link explains/mentions about this.


Apologies if it's too basic and thanks a lot in advance,
