Following that, there are three bytes for the "Payload Size" denoting length of the "Payload Data", then four bytes for the "Timestamp" in milliseconds (with the last byte used to extend the first three bytes), the next 3 bytes for the "Stream ID" (incremented for multiple streams of the same type), and finally followed by the actual payload data. There is a direct relation between the fields encountered in an FLV Tag and those found in a RTMP packet, as for example the FLV Packet Type field uses the same numeric values as the RTMP Chunk Type field (ex. 0x08 for audio and 0x09 for video). FLV tags are thus converted into RTMP packets when the file is streamed through a Flash Media Server or equivalent RTMP Server.
