Class ShadowMediaExtractor

java.lang.Object

org.robolectric.shadows.ShadowMediaExtractor

@Implements(android.media.MediaExtractor.class)
public class ShadowMediaExtractor
extends Object

A shadow for the MediaExtractor class.

Returns data previously injected by addTrack(DataSource, MediaFormat, byte[]).

Note several limitations, due to not using actual media codecs for decoding:

• Only one track may be selected at a time; multi-track selection is not supported.
• advance() will advance by the size of the last read (i.e. the return value of the last call to readSampleData(ByteBuffer, int)).
• MediaExtractor.getSampleTime() and MediaExtractor.getSampleSize() are unimplemented.
• MediaExtractor#seekTo() is unimplemented.

Method Details

addTrack

public static void addTrack(DataSource dataSource,
 MediaFormat format,
 byte[] sampleData)

Adds a track of data to an associated DataSource.

Parameters:

format - the format which will be returned by MediaExtractor.getTrackFormat(int)

sampleData - the data which will be iterated upon and returned by MediaExtractor.readSampleData(ByteBuffer, int).

setMetrics

public static void setMetrics(DataSource dataSource,
 PersistableBundle metrics)

Sets metrics for an associated DataSource.

Parameters:

metrics - the data which will be returned by MediaExtractor.getMetrics().
