In general I'm fine with the idea, but this needs some testing and
IIRC there was some framework problem which needed to be fixed
(e.g. in case of variable input frame size), the plan was to replace
the current use of vsrc_buffer with a source more strictly integrated
Sadly I can't guarantee I can commit the time to do it myself, so
patches are welcome, or you may file a ticket so we'll remember the
