如何设置MediaCodec编码H.264视频的average+max码率？

MediaFormat format = MediaFormat.createVideoFormat("video/avc", width, height);
format.setInteger(MediaFormat.KEY_BIT_RATE, averageBitRate); // 设置平均码率
format.setInteger(MediaFormat.KEY_MAX_BIT_RATE, maxBitRate); // 设置最大码率
format.setInteger(MediaFormat.KEY_FRAME_RATE, frameRate); // 设置帧率
format.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, iFrameInterval); // 设置关键帧间隔

MediaCodec codec = MediaCodec.createEncoderByType("video/avc");
codec.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

codec.start();

ByteBuffer[] inputBuffers = codec.getInputBuffers();
ByteBuffer[] outputBuffers = codec.getOutputBuffers();

int inputBufferIndex = codec.dequeueInputBuffer(timeout);
if (inputBufferIndex >= 0) {
    ByteBuffer inputBuffer = inputBuffers[inputBufferIndex];
    inputBuffer.clear();
    inputBuffer.put(inputData);
    codec.queueInputBuffer(inputBufferIndex, 0, inputData.length, presentationTimeUs, 0);
}

int outputBufferIndex = codec.dequeueOutputBuffer(bufferInfo, timeout);
if (outputBufferIndex >= 0) {
    ByteBuffer outputBuffer = outputBuffers[outputBufferIndex];
    // 处理编码后的视频数据
    codec.releaseOutputBuffer(outputBufferIndex, false);
}

codec.stop();
codec.release();
