ProgressiveMediaSource (ExoPlayer library)

java.lang.Object
- com.google.android.exoplayer2.source.BaseMediaSource
- - com.google.android.exoplayer2.source.ProgressiveMediaSource

All Implemented Interfaces:

MediaSource
```
public final class ProgressiveMediaSource
extends BaseMediaSource
```
Provides one period that loads data from a Uri and extracted using an Extractor.
If the possible input stream container formats are known, pass a factory that instantiates extractors for them to the constructor. Otherwise, pass a DefaultExtractorsFactory to use the default extractors. When reading a new stream, the first Extractor in the array of extractors created by the factory that returns true from Extractor.sniff(com.google.android.exoplayer2.extractor.ExtractorInput) will be used to extract samples from the input stream.
Note that the built-in extractor for FLV streams does not support seeking.

public Object getTag()
```
    Deprecated.
    Use getMediaItem() and MediaItem.PlaybackProperties.tag instead.
    
    Specified by:
    
    getTag in interface MediaSource
  - getMediaItem
```
public MediaItem getMediaItem()
```
    Description copied from interface: MediaSource
    
    Returns the MediaItem whose media is provided by the source.
    
    Specified by:
    
    getMediaItem in interface MediaSource
  - prepareSourceInternal
```
protected void prepareSourceInternal(@Nullable
                                     TransferListener mediaTransferListener)
```
    Description copied from class: BaseMediaSource
    
    Starts source preparation and enables the source, see BaseMediaSource.prepareSource(MediaSourceCaller, TransferListener). This method is called at most once until the next call to BaseMediaSource.releaseSourceInternal().
    
    Specified by:
    
    prepareSourceInternal in class BaseMediaSource
    
    Parameters:
    
    mediaTransferListener - The transfer listener which should be informed of any media data transfers. May be null if no listener is available. Note that this listener should usually be only informed of transfers related to the media loads and not of auxiliary loads for manifests and other data.
  - maybeThrowSourceInfoRefreshError
```
public void maybeThrowSourceInfoRefreshError()
```
    Description copied from interface: MediaSource
    
    Throws any pending error encountered while loading or refreshing source information.
    Should not be called directly from application code.
    Must only be called after MediaSource.prepareSource(MediaSourceCaller, TransferListener).
    
    Specified by:
    
    maybeThrowSourceInfoRefreshError in interface MediaSource
  - createPeriod
```
public MediaPeriod createPeriod(MediaSource.MediaPeriodId id,
                                Allocator allocator,
                                long startPositionUs)
```
    Description copied from interface: MediaSource
    
    Returns a new MediaPeriod identified by periodId.
    Should not be called directly from application code.
    Must only be called if the source is enabled.
    
    Specified by:
    
    createPeriod in interface MediaSource
    
    Parameters:
    
    id - The identifier of the period.
    
    allocator - An Allocator from which to obtain media buffer allocations.
    
    startPositionUs - The expected start position, in microseconds.
    
    Returns:
    
    A new MediaPeriod.
  - releasePeriod
```
public void releasePeriod(MediaPeriod mediaPeriod)
```
    Description copied from interface: MediaSource
    
    Releases the period.
    Should not be called directly from application code.
    
    Specified by:
    
    releasePeriod in interface MediaSource
    
    Parameters:
    
    mediaPeriod - The period to release.
  - releaseSourceInternal
```
protected void releaseSourceInternal()
```
    Description copied from class: BaseMediaSource
    
    Releases the source, see BaseMediaSource.releaseSource(MediaSourceCaller). This method is called exactly once after each call to BaseMediaSource.prepareSourceInternal(TransferListener).
    
    Specified by:
    
    releaseSourceInternal in class BaseMediaSource
  - onSourceInfoRefreshed
```
public void onSourceInfoRefreshed(long durationUs,
                                  boolean isSeekable,
                                  boolean isLive)
