本文主要参考了这篇文章 全志D1-H芯片 如何在tina使用tplayerdemo 进行rtsp拉流说明？_tina 播放裸流-CSDN博客
使能 RTSP
进入到 SDK 的 package/allwinner 目录下，这个目录下是一个 git 仓库
新建一个名字为 support_rtsp.patch 的文件，写入以下内容

用 git apply 来运行 patch 补丁
git apply support_rtsp.patch
然后运行 make menuconfig 打开配置菜单，搜索 rtsp 看到的第一个就是了，把它使能，然后编译、打包、烧录到开发板
这时就可以用开发板来进行“拉流”了
RTSP 推流
有拉当然还得有推，推流用 Windows 的机器，需要先开放几个端口，rtsp 的话用的默认是 8554 端口，这里直接用一个现成的工具，省去反复开端口的麻烦
- 可执行文件 GitHub - bluenviron/mediamtx: Ready-to-use SRT / WebRTC / RTSP / RTMP / LL-HLS media server and media proxy that allows to read, publish, proxy, record and playback video and audio streams. ，这个工具会根据 yml 来打开一些常用的端口
- yml 文件 mediamtx/mediamtx.yml at main · bluenviron/mediamtx · GitHub 可以直接使用仓库中的这个文件
- 把上面两个文件放在同一目录
直接运行，可以从日志中看到打开了很多常用的端口
然后再打开一个终端来运行推流，指定端口到8554端口，事先准备的 input.mp4 文件也在当前目录
ffmpeg -re -stream_loop -1 -i input.mp4 -c copy -f rtsp rtsp://127.0.0.1:8554/input.mp4
这时推流已经就位了，下面开始在开发板上面进行拉流的操作
RTSP 拉流
完成了之前的步骤后，开发板进行 RTSP 拉流就比较容易了，联网、拉流即可
先连接上 Wi-Fi
wifi_connect_ap_test [ssid] [password]
然后用 tplayerdemo 来拉流播放
tplayerdemo rtsp://192.168.0.109:8554/input.mp4
可以看到视频可以播放到 HDMI 的输出了，日志如下
