Method Summary

Modifier and Type	Method and Description
void	onDownstreamFormatChanged(int sourceId, Format format, int trigger, long mediaTimeMs) Invoked when the downstream format changes (i.e.
void	onLoadCanceled(int sourceId, long bytesLoaded) Invoked when the current upstream load operation is canceled.
void	onLoadCompleted(int sourceId, long bytesLoaded, int type, int trigger, Format format, long mediaStartTimeMs, long mediaEndTimeMs, long elapsedRealtimeMs, long loadDurationMs) Invoked when the current load operation completes.
void	onLoadError(int sourceId, IOException e) Invoked when an error occurs loading media data.
void	onLoadStarted(int sourceId, long length, int type, int trigger, Format format, long mediaStartTimeMs, long mediaEndTimeMs) Invoked when an upstream load is started.
void	onUpstreamDiscarded(int sourceId, long mediaStartTimeMs, long mediaEndTimeMs) Invoked when data is removed from the back of the buffer, typically so that it can be re-buffered using a different representation.

Method Detail

onLoadStarted

void onLoadStarted(int sourceId,
                   long length,
                   int type,
                   int trigger,
                   Format format,
                   long mediaStartTimeMs,
                   long mediaEndTimeMs)

Invoked when an upstream load is started.

Parameters:

sourceId - The id of the reporting SampleSource.

length - The length of the data being loaded in bytes, or C.LENGTH_UNBOUNDED if the length of the data is not known in advance.

type - The type of the data being loaded.

trigger - The reason for the data being loaded.

format - The particular format to which this data corresponds, or null if the data being loaded does not correspond to a format.

mediaStartTimeMs - The media time of the start of the data being loaded, or -1 if this load is for initialization data.

mediaEndTimeMs - The media time of the end of the data being loaded, or -1 if this load is for initialization data.

onLoadCompleted

void onLoadCompleted(int sourceId,
                     long bytesLoaded,
                     int type,
                     int trigger,
                     Format format,
                     long mediaStartTimeMs,
                     long mediaEndTimeMs,
                     long elapsedRealtimeMs,
                     long loadDurationMs)

Invoked when the current load operation completes.

Parameters:

sourceId - The id of the reporting SampleSource.

bytesLoaded - The number of bytes that were loaded.

type - The type of the loaded data.

trigger - The reason for the data being loaded.

format - The particular format to which this data corresponds, or null if the loaded data does not correspond to a format.

mediaStartTimeMs - The media time of the start of the loaded data, or -1 if this load was for initialization data.

mediaEndTimeMs - The media time of the end of the loaded data, or -1 if this load was for initialization data.

elapsedRealtimeMs - elapsedRealtime timestamp of when the load finished.

loadDurationMs - Amount of time taken to load the data.

onLoadCanceled

void onLoadCanceled(int sourceId,
                    long bytesLoaded)

Invoked when the current upstream load operation is canceled.

Parameters:

sourceId - The id of the reporting SampleSource.

bytesLoaded - The number of bytes that were loaded prior to the cancellation.

onLoadError

void onLoadError(int sourceId,
                 IOException e)

Invoked when an error occurs loading media data.

Parameters:

sourceId - The id of the reporting SampleSource.

e - The cause of the failure.

onUpstreamDiscarded

void onUpstreamDiscarded(int sourceId,
                         long mediaStartTimeMs,
                         long mediaEndTimeMs)

Invoked when data is removed from the back of the buffer, typically so that it can be re-buffered using a different representation.

Parameters:

sourceId - The id of the reporting SampleSource.

mediaStartTimeMs - The media time of the start of the discarded data.

mediaEndTimeMs - The media time of the end of the discarded data.

onDownstreamFormatChanged

void onDownstreamFormatChanged(int sourceId,
                               Format format,
                               int trigger,
                               long mediaTimeMs)

Invoked when the downstream format changes (i.e. when the format being supplied to the caller of SampleSource.SampleSourceReader.readData(int, long, com.google.android.exoplayer.MediaFormatHolder, com.google.android.exoplayer.SampleHolder) changes).

Parameters:

sourceId - The id of the reporting SampleSource.

format - The format.

trigger - The trigger specified in the corresponding upstream load, as specified by the ChunkSource.

mediaTimeMs - The media time at which the change occurred.
