Method Detail

init
```
void init(IDvrManifest dvrManifest)
```
Initialize the chunk ID handler

Parameters:

dvrManifest -

setVideoManifest
```
void setVideoManifest(com.wowza.wms.dvr.DvrChannelManifest videoManifest)
```
Set the video manifest for this handler

Parameters:

videoManifest -

setAudioManifest
```
void setAudioManifest(com.wowza.wms.dvr.DvrChannelManifest audioManifest)
```
Set the audio manifest for this handler

Parameters:

audioManifest -

setDataManifest
```
void setDataManifest(com.wowza.wms.dvr.DvrChannelManifest dataManifest)
```
Set the data manifest for this handler

Parameters:

dataManifest -

setMetadataManifest
```
void setMetadataManifest(com.wowza.wms.dvr.DvrChannelManifest onMetaManifest)
```
Set the meta data manifest for this handler

Parameters:

onMetaManifest -

setCodecManifest
```
void setCodecManifest(com.wowza.wms.dvr.DvrChannelManifest codecManifest)
```
Set the codec manifest for this handler

Parameters:

codecManifest -

onAssignChunkId
```
long onAssignChunkId(String streamName,
                     com.wowza.wms.dvr.DvrPacketHolder vPackets,
                     com.wowza.wms.dvr.DvrPacketHolder aPackets)
```
This returns the chunkID to use for the nDVR chunk to be stored. It MUST return a consist number based on the state of the manifests/packets provided, i.e. return the same answer if no changes are made between calls.

Parameters:

streamName -

vPackets -

aPackets -

Returns:

setDVRStore

void setDVRStore(IDvrStreamStore dvrStore)

onAssignChunkId

long onAssignChunkId(String streamName,
                     AMFPacket dataPacket)

getLastAssignedChunkId
```
long getLastAssignedChunkId()
```

setLastSkippedChunkId

void setLastSkippedChunkId(long chunkId)
