    144142This block is mandatory and must be the last block of the stream. Tags are written after this block.

     146This file format can be used for streaming. The "SI" block is used as synchronization marker. The decoder will scan for a "SI" block and check the block CRC. Once the decoder is synchronized, it will start decoding. It's up to the streaming server to choose when to send "SI" block.[[BR]]
     147There is currently no way to send tags during playback. This must be changed (a tag block ?).
