| 19 | +## jtt1078-video-server | ||
| 20 | +基于JT/T 1078协议实现的视频转播服务器，当车机服务器端主动下发**音视频实时传输控制**消息（0x9101）后，车载终端连接到此服务器后，发送指定摄像头所采集的视频流，此项目服务器完成音视频数据接收并转码，完成转播的流程，提供各平台的播放支撑。 | ||
| 21 | + | ||
| 22 | +同时，本项目在配置 **ffmpeg路径** 及 **rtmp url** 后，将同时输出一路到 **RTMP** 服务器上去，为移动端播放提供音视频支持（注意，由于旁路的RTMP流是通过ffmpeg子进程实现，并且有音频转码的过程，所以性能将有很大的下降）。 | ||
| 23 | + | ||
| 24 | +> 非常感谢 **孤峰赏月/hx（[github/jelycom](https://github.com/jelycom)）** 提供的mp3音频支持。 | ||
| 25 | + | ||
| 26 | +## 分支说明 | ||
| 27 | +原项目有4个分支不同的实现方式，现将其它分支全部删除，已经用不上了。 | ||
| 28 | +配置了ffmpeg和rtmp，可以想办法同时输出到比如HLS等。 | ||
| 29 | + | ||
| 30 | +> 有其它语言的开发者，可以参考我的“[JTT/1078音视频传输协议开发指南](https://www.hentai.org.cn/article?id=8)”，我所知道的官方文档里的错误或是缺陷以及坑，我全部写了下来，希望对你有帮助。 | ||
| 31 | + | ||
| 32 | +### 项目说明 | ||
| 33 | +本项目接收来自于车载终端发过来的音视频数据，视频直接封装为FLV TAG，音频完成G.711A、G.711U、ADPCMA、G726到PCM的转码，并使用MP3压缩后再封装为FLV TAG。 | ||
| 34 | + | ||
| 35 | +#### 视频编码支持 | ||
| 36 | +目前几乎所有的终端视频，默认的视频编码都是h264，打包成flv也是非常简单的，有个别厂家使用avs，但是我没有碰到过。本项目目前也只支持h264编码的视频。 | ||
| 37 | + | ||
| 38 | +#### 音频编码支持 | ||
| 39 | +|音频编码|支持|备注| | ||
| 40 | +|---|---|---| | ||
| 41 | +|G.711A|Y|支持| | ||
| 42 | +|G.711U|Y|支持| | ||
| 43 | +|ADPCMA|Y|支持| | ||
| 44 | +|G.726|Y|支持| | ||
| 45 | + | ||
| 46 | +音频编码太多，也没那么多设备可以测试的，比较常见的就G.711A和ADPCMA这两种，本程序对于不支持的音频，将作 **静音处理** 。 | ||
| 47 | + | ||
| 48 | +#### 音频编码转码扩展实现 | ||
| 49 | +继承并实现`AudioCodec`类的抽象方法，完成任意音频到PCM编码的转码过程，并且补充`AudioCodec.getCodec()`工厂方法即可。`AudioCodec`抽象类原型如下： | ||
| 50 | +```java | ||
| 51 | +public abstract class AudioCodec | ||
| 52 | +{ | ||
| 53 | + // 转换至PCM | ||
| 54 | + public abstract byte[] toPCM(byte[] data); | ||
| 55 | + // 由PCM转为当前编码，可以留空，反正又没有调用 | ||
| 56 | + public abstract byte[] fromPCM(byte[] data); | ||
| 57 | +} | ||
| 58 | +``` | ||
| 59 | + | ||
| 60 | +### 准备工具 | ||
| 61 | +项目里准备了一个测试程序（`src/main/java/cn.org.hentai.jtt1078.test.VideoPushTest.java`），以及一个数据文件（`src/main/resources/tcpdump.bin`），数据文件是通过工具采集的一段几分钟时长的车载终端发送上来的原始消息包，测试程序可以持续不断的、慢慢的发送数据文件里的内容，用来模拟车载终端发送视频流的过程。 | ||
| 62 | + | ||
| 63 | +另外，新增了 `cn.org.hentai.jtt1078.test.RTPGenerate` 类，用于读取bin文件，并且修改SIM卡号和通道号，创建大量数据文件以便于压力测试。 | ||
| 64 | + | ||
| 65 | +### 测试步骤 | ||
| 66 | +1. 配置好服务器端，修改`app.properties`里的配置项。 | ||
| 67 | +2. 直接在IDE里运行`cn.org.hentai.jtt1078.app.VideoServerApp`，或对项目进行打包，执行`mvn package`，执行`java -jar jtt1078-video-server-1.0-SNAPSHOT.jar`来启动服务器端。 | ||
| 68 | +3. 运行`VideoPushTest.java`，开始模拟车载终端的视频推送。 | ||
| 69 | +4. 开始后，控制台里会输出显示**start publishing: 013800138999-2**的字样 | ||
| 70 | +5. 打开浏览器，输入 **http://localhost:3333/test/multimedia#013800138999-2** 后回车 | ||
| 71 | +6. 点击网页上的**play video**，开始播放视频 | ||
| 72 | + | ||
| 73 | +### 测试环境 | ||
| 74 | +我在我自己的VPS上搭建了一个1078音视频环境，完全使用了**flv**分支上的代码来创建，各位可以让终端将音视频发送到此服务器或是使用**netcat**等网络工具发送模拟数据来仿真终端，来体验音视频的效果。下面我们说一下通过**netcat**来模拟终端的方法： | ||
| 75 | + | ||
| 76 | +|标题|说明| | ||
| 77 | +|---|---| | ||
| 78 | +|1078音视频服务器|185.251.248.4:10780| | ||
| 79 | +|实时音视频播放页面|http://1078.hentai.org.cn/test/multimedia#SIM-CHANNEL| | ||
| 80 | + | ||
| 81 | +1. 首先，本项目的 **/src/main/resources/** 下的 **tcpdump.bin** 即为我抓包存下来的终端音视频数据文件，通过`cat tcpdump.bin | pv -L 40k -q | nc 185.251.248.4 10780`即可以每秒40kBPS的速度，向服务器端持续的发送数据。 | ||
| 82 | +2. 在浏览器里打开**http://1078.hentai.org.cn/test/multimedia#SIM-CHANNEL** （注意替换掉后面的SIM和CHANNEL，即终端的SIM卡号，不足12位前面补0，CHANNEL即为通道号），然后点击网页上的**play video**即可。 | ||
| 83 | + | ||
| 84 | +> 由于我的服务器IP随时可能会发生变化，建设在尝试连接测试服务器前，先通过`ping www.hentai.org.cn`来确定最新的IP。 | ||

| 180 | +### 项目打包说明 | ||
| 181 | +通过**mvn package**直接打包成jar包，通过`java -jar jtt1078-video-server-1.0-SNAPSHOT.jar`即可运行，最好把**app.properties**和**multimedia.html**一并放在同一个目录下，因为项目会优先读取文件系统中的配置文件信息。而如果没有本地测试的需求，**multimedia.html**可以不要。 | ||
| 182 | + | ||
| 183 | +### 注意事项 | ||
| 184 | +1. 本项目为JT 1078协议的流媒体服务器部分的实现，不包括1078协议的控制消息交互部分，就是在0x9101指令下发后，终端连接到的音视频服务器的实现。 | ||
| 185 | +2. 在一般的浏览器里，比如Chrome下，浏览器限制了对于同一个域名的连接最多只能够有6个并发，所以如果要同时播放多路视频，需要准备多个域名或是端口，通过轮循分配的方式，把视频的传输连接，分配到不同的URL上去。 | ||
| 186 | + | ||
| 187 | +### 致谢 | ||
| 188 | +本项目一开始只是个简单的示例项目，在开源、建立QQ交流群后，得到了大批的同道中人的帮助和支持，在此表示谢意。本项目尚未完全完善，非常高兴能够有更多的朋友一起加入进来，一起提出更加闪亮的想法，建设更加强大的视频监控平台！ | ||

| 10 | + * coding algorithm. Essentially, this implementation is identical to | ||
| 11 | + * the bit level description except for a few deviations which | ||
| 12 | + * take advantage of work station attributes, such as hardware 2's | ||
| 13 | + * complement arithmetic and large memory. Specifically, certain time | ||
| 14 | + * consuming operations such as multiplications are replaced | ||
| 15 | + * with lookup tables and software 2's complement operations are | ||
| 16 | + * replaced with hardware 2's complement. | ||
| 17 | + * <p> | ||
| 18 | + * The deviation from the bit level specification (lookup tables) | ||
| 19 | + * preserves the bit level performance specifications. | ||
| 20 | + * <p> | ||
| 21 | + * As outlined in the G.726 Recommendation, the algorithm is broken | ||
| 22 | + * down into modules. Each section of code below is preceded by | ||
| 23 | + * the name of the module which it is implementing. | ||
| 24 | + * <p> | ||
| 25 | + * This implementation is based on the ANSI-C language reference implementations | ||
| 26 | + * of the CCITT (International Telegraph and Telephone Consultative Committee) | ||
| 27 | + * G.711, G.721 and G.723 voice compressions, provided by Sun Microsystems, Inc. | ||
