virtual void remove_stream(const uint32_t stream_num)=0
Unregister the stream number. All packets destined to the stream will be dropped.
virtual zero_copy_if::sptr make_stream(const uint32_t stream_num)=0
Make a virtual transport for the specified stream number.
static sptr make(zero_copy_if::sptr base_xport, stream_classifier_fn classify_fn, size_t max_streams)
Make a new demuxer from a transport and parameters.
virtual size_t get_num_dropped_frames() const =0
Get number of frames dropped due to unregistered streams.
