Created attachment 40890 [details] patch for proposed solution on fs-funnel I am working on video conference application using gstreamer & farsight2 framework. In video conference pipeline, the element “fs-funnel” is used after remote video stream is decoded, finally the stream is sent to xvimagesink for rendering. But the sink pad of “fs-funnel” is created by request dynamically and there is no associate buffer allocation handler. So during runtime, the output buffer allocation request chain will be chopped in “fs-funnel” and only traditional buffer will be allocated to upstream elements as output buffer. In that case, the downstream buffer allocation (device specific buffer: XvImage) will not be enabled and lots of buffer allocation/de-allocation and memory copy operations incurred. That will cause resource (CPU & power) waste finally, especially at mobile and thin client side.
