acquire_buffer

buffer should point to a memory location that can hold a pointer to the new buffer. When the pool is empty, this function will by default block until a buffer is released into the pool again or when the pool is set to flushing or deactivated.

params can contain optional parameters to influence the allocation.

Parameters:

this	a BufferPool
buffer	a location for a Buffer
params	parameters.

Returns:

a FlowReturn such as gst_flow_flushing when the pool is inactive.
