drain()

bool MayaFlux::IO::AudioEncodeContext::drain

(

FFmpegMuxContext &

mux

)

Flush the FIFO remainder and encoder internal delay to the mux.

Pads the final partial FIFO frame with silence if needed, sends it, then sends a null frame to signal EOS to the encoder and drains all buffered output packets. Call once before FFmpegMuxContext::close().

Parameters

mux	Mux context to receive remaining packets.

Returns

True if all remaining packets were written successfully.
