好多开发者有这样的诉求,想把本地录制的MP4文件,以实时流数据的形式,推送到RTMP服务器,注入轻量级RTSP服务,或者对接到GB28181平台,这块前几年我们就有对接。

本次以MediaExtractor为例,先利用MediaExtractor,把mp4文件的音视频数据分离,然后调用我们publisher模块,实现编码后的数据对接到RTMP服务器、轻量级RTSP服务或GB28181平台即可,废话不多说,上代码,由于实例代码比较简单,不再赘述用法:

/*
* SmartPublisherActivity.java
* Github: https://github.com/daniulive/SmarterStreaming
*/
private void InitMediaExtractor(){
File mFile = new File("/storage/emulated/0/","2022.mp4");

if (!mFile.exists()){
Log.e(TAG, "mp4文件不存在");
return;
}

MediaExtractor mediaExtractor = new MediaExtractor();
try {
mediaExtractor.setDataSource(mFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}

int count = mediaExtractor.getTrackCount();//获取轨道数量
Log.e(TAG, "轨道数量 = "+count);

for (int i = 0; i < count; i++)
{
MediaFormat trackFormat = mediaExtractor.getTrackFormat(i);
String mineType = trackFormat.getString(MediaFormat.KEY_MIME);
Log.e(TAG, i + "编号通道格式 = " + mineType);

//视频信道
if (mineType.startsWith("video/")) {
video_track_index = i;
is_has_video = true;

try {
video_media_extractor.setDataSource(mFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}

if(mineType.equals("video/avc"))
{
video_codec_id = 1;
}
else if(mineType.equals("video/hevc"))
{
video_codec_id = 2;
}

int width = trackFormat.getInteger(MediaFormat.KEY_WIDTH);
int height = trackFormat.getInteger(MediaFormat.KEY_HEIGHT);
long duration = trackFormat.getLong(MediaFormat.KEY_DURATION);//总时间
int video_fps = trackFormat.getInteger(MediaFormat.KEY_FRAME_RATE);//帧率
max_sample_size = trackFormat.getInteger(MediaFormat.KEY_MAX_INPUT_SIZE);//获取视频缓存输出的最大大小

Log.e(TAG, "video width " + width + ", height: " + height + ", duration: " + duration + ", max_sample_size: " + max_sample_size + ", fps: " + video_fps);
}

//音频信道
if (mineType.startsWith("audio/")) {
audio_track_index = i;
is_has_audio = true;

try {
audio_media_extractor.setDataSource(mFile.getAbsolutePath());
} catch (IOException e) {
e.printStackTrace();
}


if(mineType.equals("audio/mp4a-latm"))
{
audio_codec_id = 0x10002;
}

audio_sample_rate = trackFormat.getInteger(MediaFormat.KEY_SAMPLE_RATE);//获取采样率
int audioTrackBitrate = trackFormat.getInteger(MediaFormat.KEY_BIT_RATE); //获取比特率
int channels = trackFormat.getInteger(MediaFormat.KEY_CHANNEL_COUNT); //获取声道数量

视频数据处理,先切到视频信道,然后调用readSampleData(),读取到video数据后,判断是不是关键帧,是关键帧的话,带上sps pps(如果是h265 带上vps sps pps),一般来说,比如无人机等设备回调,大多都贴心的实现了关键帧前携带sps pps,也有的设备是单独发sps pps,所以,对接的时候,可以先把数据打印出来看看,具体问题具体分析即可,获取video数据后,通过SmartPublisherPostVideoEncodedData()投递到底层:

//切换到视频信道

Android平台实现mp4文件实时推送RTMP|轻量级RTSP服务|GB28181平台_GB28181 MP4_02

if(IsVpsSpsPps(video_header_checker_buffer, video_codec_id))
{
is_key_frame = true;
}

if ( isPushing || isRTSPPublisherRunning || isGB28181StreamRunning) {
libPublisher.SmartPublisherPostVideoEncodedData(publisherHandle, video_codec_id, byteBuffer, video_sample_size, is_key_frame?1:0, cur_sample_time, cur_sample_time);
}

audio也是类似的流程,audio有一点,需要先拿到audio param info,然后,调用readSampleData()获取到audio数据,调用SmartPublisherPostAudioEncodedData()投递出去即可。

byte[] audio_param_info = GetAudioParamInfo();
ByteBuffer parameter_info = ByteBuffer.allocateDirect(2);
parameter_info.put(audio_param_info);

int parameter_info_size = 2;

audio_media_extractor.selectTrack(audio_track_index);

int audio_sample_size = audio_media_extractor.readSampleData(byteBuffer, 0);

if(audio_sample_size < 0)
{
Log.i(TAG, "audio reach the end..");
break;
}

long cur_sample_time = audio_media_extractor.getSampleTime()/1000;

if ( isPushing || isRTSPPublisherRunning || isGB28181StreamRunning) {
libPublisher.SmartPublisherPostAudioEncodedData(publisherHandle, audio_codec_id, byteBuffer, audio_sample_size, 0, cur_sample_time, parameter_info, parameter_info_size);

数据投递讲完后,就是推送模块接口的处理,获取到的数据,是可以对接到RTMP推送模块,或者轻量级RTSP服务亦或GB28181设备接入模块,这些模块,都可以在一个实例内完成,所以,我们先调用OpenPushHandle()完成publisherHandle生成,并设置event callback。

private boolean OpenPushHandle()
{
if(publisherHandle != 0)
{
return true;
}

int audio_opt = 2;
int video_opt = 2;

int videoWidth = 640;
int videoHeight = 480;

publisherHandle = libPublisher.SmartPublisherOpen(context_, audio_opt, video_opt,
videoWidth, videoHeight);

if (publisherHandle == 0 )
{
Log.e(TAG, "OpenPushHandle failed!");
return false;
}

Log.i(TAG, "publisherHandle=" + publisherHandle);

libPublisher.SetSmartPublisherEventCallbackV2(publisherHandle, new EventHandePublisherV2());

return true;
}
