Method Detail

hasMetaData

boolean hasMetaData()
Returns a boolean stating whether the mp4 has metadata

Returns:
boolean true if file has injected metadata, false otherwise

setMetaData

void setMetaData(IMetaData<?,?> metadata)
                 throws FileNotFoundException,
                        IOException
Sets the metadata

Parameters:
metadata - Metadata object
Throws:
FileNotFoundException - File not found
IOException - Any other I/O exception

setMetaService

void setMetaService(IMetaService service)
Sets the MetaService through Spring

Parameters:
service - Metadata service

getMetaData

IMetaData<?,?> getMetaData()
                           throws FileNotFoundException
Returns a map of the metadata

Returns:
metadata File metadata
Throws:
FileNotFoundException - File not found

hasKeyFrameData

boolean hasKeyFrameData()
Returns a boolean stating whether a mp4 has keyframedata

Returns:
boolean true if file has keyframe metadata, false otherwise

setKeyFrameData

void setKeyFrameData(Map<?,?> keyframedata)
Sets the keyframe data of a mp4 file

Parameters:
keyframedata - Keyframe metadata

getKeyFrameData

Map<?,?> getKeyFrameData()

Returns:
keyframedata Keyframe metadata

refreshHeaders

void refreshHeaders()
                    throws IOException

Throws:
IOException - Any I/O exception

flushHeaders

void flushHeaders()
                  throws IOException
Flushes Header

Throws:
IOException - Any I/O exception

readerFromNearestKeyFrame

ITagReader readerFromNearestKeyFrame(int seekPoint)
Returns a Reader closest to the nearest keyframe

Parameters:
seekPoint - Point in file we are seeking around
Returns:
reader Tag reader closest to that point
