finish_frame

Description:

public FlowReturn finish_frame (owned Buffer? buf, int frames)

buf may be NULL in which case the indicated number of frames are discarded and considered to have produced no output (e.g. lead-in or setup frames). Otherwise, source pad caps must be set when it is called with valid data in buf.

Note that a frame received in handle_frame may be invalidated by a call to this function.

Parameters:

this	a Decoder
buf	decoded data
frames	number of decoded frames represented by decoded data

Returns:

a FlowReturn that should be escalated to caller (of caller)
