This is a utility function primarily used for IMediaWriters. It is a way of taking the discrete audio/video/data packets and timecodes and interleaving them into a single list of AMFPacket objects. The currentTCs array is an array of longs containing the last timecode for each of the packet types FLV_TCINDEX* (long[3]). This array will be used to calculate the absolute timecode for a given packet. For example if the relative timecode for an audio packet is 26 and the currentTCs value for the audio channel is 1003 then the absolute timecode for that packet will be 1029. The currentTCs array will be updated after this call to reflect the absolute timecode of the last packet processed of each type.

Parameters:: audioPackets - list of audio packets (ByteBuffer); videoPackets - list of video packets (ByteBuffer); dataPackets - list of data packets (ByteBuffer); audioTCs - list of relative audio timecodes (Long); videoTCs - list of relative video timecodes (Long); dataTCs - list of relative data timecodes (Long); dataTypes - list of integer packets types (IVHost.CONTENTTYPE_DATA0, IVHost.CONTENTTYPE_DATA3) - if null assumed to be IVHost.CONTENTTYPE_DATA0; currentTCs - array of longs containing last TCs written for each packet type FLV_TCINDEX* (long[3]). Last timecode written for each packet type wil be returned in this same array.
Returns:: List of AMFPacket objects sorted by timecodes

                                com.wowza.util.IFLVWriterAdjustTimecode dataPacketTimecodeAdjuster)

Write a bunch of packets to .flv file all at once. The packets will be sorted by timecode as written

Parameters:: ds - OutputStream; audioPackets - list of audio packets (ByteBuffer); videoPackets - list of video packets (ByteBuffer); dataPackets - list of data packets (ByteBuffer); audioTCs - list of relative audio timecodes (Long); videoTCs - list of relative video timecodes (Long); dataTCs - list of relative data timecodes (Long); dataTypes - list of integer packets types (IVHost.CONTENTTYPE_DATA0, IVHost.CONTENTTYPE_DATA3) - if null assumed to be IVHost.CONTENTTYPE_DATA0; currentTCs - array of longs containing last TCs written for each packet type FLV_TCINDEX* (long[3]). Last timecode written for each packet type wil be returned; dataPacketTimecodeAdjuster - class that implements the IFLVWriterAdjustTimecode interface for adjusting timecodes in this same array.

Write a bunch of packets to .flv file all at once. The packets will be sorted by timecode as written

Parameters:: ds - OutputStream; audioPackets - list of audio packets (ByteBuffer); videoPackets - list of video packets (ByteBuffer); dataPackets - list of data packets (ByteBuffer); audioTCs - list of relative audio timecodes (Long); videoTCs - list of relative video timecodes (Long); dataTCs - list of relative data timecodes (Long); currentTCs - array of longs containing last TCs written for each packet type FLV_TCINDEX* (long[3]). Last timecode written for each packet type wil be returned in this same array.

writePackets

public static void writePackets(java.io.OutputStream ds,
                                java.util.List packetList,
                                long tcOffset)

Write audio/video/data packets to an .flv file. They will be written in the packetList order.

Parameters:: ds - OutputStream; packetList - List of AMFPacket objects; tcOffset - timecode offset

writeShortHeader

public static void writeShortHeader(java.io.DataOutput ds)

writeShortHeader

public static void writeShortHeader(java.io.OutputStream ds)

Write just the FLV file header (without the metadata packet)

Parameters:: ds - OutputStream
