[gst-devel] adder with nonblocking pads

[Edward Hervey]

Hi,

  You might want to have a look at liveadder (in gst-plugins-bad), which
allows doing mixing of live streams. Instead of waiting for data to be
available on all streams, it waits up to a certain (configurable) delay
before processing data on any incoming streams.
