方法详细资料

addTrack

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.

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).

抛出:

java.lang.IllegalArgumentException - if format is invalid.

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

writeSampleData

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.)

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.
