Make delay one stream, not all

[Johan Basore]

Hello everyone,

I am building a player with gstreamer. I can't find out a way to implement this.
I have two streams from a filsrc, video stream and audio stream. audio must be played 3 seconds later than video stream. I am using c api.

How can I do this?

There's the ts-offset property on all sinks, that can be used for this
in many cases. For the more general case, see gst_pad_set_offset()
which would already work before sinks.

Thanks for your answer,

Yes, adder does not implement any synchronization of the input streams
at all. You need to use audiomixer and then can use the pad offsets.
