+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on a TS feed has been enabled using the start_filtering\(\) function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * "wrapped" to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.
