构造器详细资料

TuSdkMediaFileMuxer

public TuSdkMediaFileMuxer()

方法详细资料

setMediaMuxerFormat

public TuSdkMediaFileMuxer setMediaMuxerFormat(int mediaMuxerFormat)

The format of the output media file. default: MUXER_OUTPUT_MPEG_4

setPath

public TuSdkMediaFileMuxer setPath(java.lang.String path)

The path of the output media file.

setFileDescriptor

public TuSdkMediaFileMuxer setFileDescriptor(java.io.FileDescriptor fileDescriptor)

The FileDescriptor of the output media file.

setVideoOperation

public void setVideoOperation(TuSdkEncodecOperation videoOperation)

视频编码处理器

setAudioOperation

public void setAudioOperation(TuSdkEncodecOperation audioOperation)

音频编码处理器

pause

public void pause()

暂停合成

resume

public TuSdkMediaFileMuxer resume()

恢复合成

isWorking

public boolean isWorking()

合成器是否开始执行

prepare

public boolean prepare()

准备开始合成

返回:

是否开始

release

public void release()

销毁

finalize

protected void finalize()
                 throws java.lang.Throwable

覆盖:

finalize 在类中 java.lang.Object

抛出:

java.lang.Throwable

addTrack

public int addTrack(android.media.MediaFormat format)

Adds a track with the specified format.

The following table summarizes support for specific format keys across android releases. Keys marked with '+:' are required.

指定者:

addTrack 在接口中 TuSdkMediaMuxer

参数:

format - The media format for the track. This must not be an empty MediaFormat.

返回:

The track index for this newly added track, and it should be used in the writeSampleData(int, java.nio.ByteBuffer, android.media.MediaCodec.BufferInfo). 如果返回-1即为添加失败

抛出:

java.lang.IllegalArgumentException - if format is invalid.

java.lang.IllegalStateException - if muxer is in the wrong state.

writeSampleData

public void writeSampleData(int trackIndex,
                            java.nio.ByteBuffer byteBuf,
                            android.media.MediaCodec.BufferInfo bufferInfo)

Writes an encoded sample into the muxer.

The application needs to make sure that the samples are written into the right tracks. Also, it needs to make sure the samples for each track are written in chronological order (e.g. in the order they are provided by the encoder.)

指定者:

writeSampleData 在接口中 TuSdkMediaMuxer

参数:

trackIndex - The track index for this sample.

byteBuf - The encoded sample.

bufferInfo - The buffer information related to this sample.

抛出:

java.lang.IllegalArgumentException - if trackIndex, byteBuf or bufferInfo is invalid.

java.lang.IllegalStateException - if muxer is in wrong state. MediaMuxer uses the flags provided in MediaCodec.BufferInfo, to signal sync frames.

setLocation

public void setLocation(float latitude,
                        float longitude)

Set and store the geodata (latitude and longitude) in the output file. This method should be called after prepare before MediaMuxer start. The geodata is stored in udta box if the output format is MediaMuxer.OutputFormat#MUXER_OUTPUT_MPEG_4, and is ignored for other output formats. The geodata is stored according to ISO-6709 standard.

参数:

latitude - Latitude in degrees. Its value must be in the range [-90, 90].

longitude - Longitude in degrees. Its value must be in the range [-180, 180].

抛出:

java.lang.IllegalArgumentException - If the given latitude or longitude is out of range.

java.lang.IllegalStateException - If this method is called after MediaMuxer start.

setOrientationHint

public void setOrientationHint(int degrees)

Sets the orientation hint for output video playback.

This method should be called after prepare before MediaMuxer start. Calling this method will not rotate the video frame when muxer is generating the file, but add a composition matrix containing the rotation angle in the output video if the output format is MediaMuxer.OutputFormat#MUXER_OUTPUT_MPEG_4 so that a video player can choose the proper orientation for playback. Note that some video players may choose to ignore the composition matrix in a video during playback. By default, the rotation degree is 0.

参数:

degrees - the angle to be rotated clockwise in degrees. The supported angles are 0, 90, 180, and 270 degrees.

抛出:

java.lang.IllegalArgumentException - if degree is not supported.

java.lang.IllegalStateException - If this method is called after MediaMuxer start.
