Methods Summary
public intdescribeContents()

        return 0;
public final intgetAudioChannelCount()
Returns the audio channel count. Valid only for {@link #TYPE_AUDIO} tracks.

        if (mType != TYPE_AUDIO) {
            throw new IllegalStateException("Not an audio track");
        }
        return mAudioChannelCount;
public final intgetAudioSampleRate()
Returns the audio sample rate, in the unit of Hz. Valid only for {@link #TYPE_AUDIO} tracks.

        if (mType != TYPE_AUDIO) {
            throw new IllegalStateException("Not an audio track");
        }
        return mAudioSampleRate;
public final android.os.BundlegetExtra()
Returns the extra information about the current track.

        return mExtra;
public final java.lang.StringgetId()
Returns the ID of the track.

        return mId;
public final java.lang.StringgetLanguage()
Returns the language information encoded by either ISO 639-1 or ISO 639-2/T. If the language is unknown or could not be determined, the corresponding value will be {@code null}.

        return mLanguage;
public final intgetType()
Returns the type of the track. The type should be one of the followings: {@link #TYPE_AUDIO}, {@link #TYPE_VIDEO} and {@link #TYPE_SUBTITLE}.

        return mType;
public final floatgetVideoFrameRate()
Returns the frame rate of the video, in the unit of fps (frames per second). Valid only for {@link #TYPE_VIDEO} tracks.

        if (mType != TYPE_VIDEO) {
            throw new IllegalStateException("Not a video track");
        }
        return mVideoFrameRate;
public final intgetVideoHeight()
Returns the height of the video, in the unit of pixels. Valid only for {@link #TYPE_VIDEO} tracks.

        if (mType != TYPE_VIDEO) {
            throw new IllegalStateException("Not a video track");
        }
        return mVideoHeight;
public final intgetVideoWidth()
Returns the width of the video, in the unit of pixels. Valid only for {@link #TYPE_VIDEO} tracks.
