Hi

At RidgeRun we have developed this set of elements for inter-pipeline
communication over the past few years. We developed them to simplify supporting
our customer's custom GStreamer based applications.  A key requirement for
these applications was dynamic control. Typical use cases included:

  * Switching between multiple source feeds.
  * Activate/deactivate buffer flow through different branches
  * Manage the state of the different branches individually
  * Handle 'some' events in individual branches (EOS typically)

Meeting these requirements using existing solutions, would require the use of
pad probes, valves, input/output selectors, bins, unlink parts of the pipeline,
flush, etc... This required a lot of careful work and was very error prone. We
continued with this approach for many iterations, but it was not robust.

Then RidgeRun discovered intervideosink/src, interaudiosink/src and
intersubsink/src. Immediately we recognized their potential. However, they did
not completely fulfilled our requirements due to the restricted caps support
and internal functionality. 

Inspired by this approach, we designed a generic buffer transmission plug-in
which effectively solved the limitations which still existed. We have just
ported this project to the GStreamer 1.0 API version, and want to share them
with the community. 

Can you evaluate them and provide feedback? We want to take it to the state
were it can be included in the GStreamer project.

The project is hosted at:

Thanks!
