Extract a buffer from the provided sample and adds it to the queue of
buffers that the appsrc element will push to its source pad. Any
previous caps that were set on appsrc will be replaced by the caps
associated with the sample if not equal.
This function does not take ownership of the
sample so the sample needs to be unreffed after calling this function.
When the block property is TRUE, this function can block until free
space becomes available in the queue.
