播放网络视频
1. 开机默认HDMI输出
网络视频将通过HDMI屏幕来显示，需要先配置HDMI输出。
修改uboot的设备树，实现开机默认HDMI显示。
进入目录：
cd /home/ubuntu/tina-d1-h/device/config/chips/d1-h/configs/nezha
修改uboot-board.dts：
vim uboot-board.dts
修改disp节点，如下：
&disp {
disp_init_enable = <1>;
disp_mode = <0>;
/*
screen0_output_type = <1>;
screen0_output_mode = <4>;
screen1_output_type = <3>;
screen1_output_mode = <10>;
*/
screen0_output_type = <3>;
screen0_output_mode = <10>;
screen1_output_type = <1>;
screen1_output_mode = <4>;
/*
screen1_output_format = <0>;
screen1_output_bits = <0>;
screen1_output_eotf = <4>;
screen1_output_cs = <257>;
screen1_output_dvi_hdmi = <2>;
screen1_output_range = <2>;
screen1_output_scan = <0>;
screen1_output_aspect_ratio = <8>;
*/
screen0_output_format = <0>;
screen0_output_bits = <0>;
screen0_output_eotf = <4>;
screen0_output_cs = <257>;
screen0_output_dvi_hdmi = <2>;
screen0_output_range = <2>;
screen0_output_scan = <0>;
screen0_output_aspect_ratio = <8>;
/*
dev0_output_type = <1>;
dev0_output_mode = <4>;
dev0_screen_id = <0>;
dev0_do_hpd = <0>;
*/
dev0_output_type = <4>;
dev0_output_mode = <10>;
dev0_screen_id = <0>;
dev0_do_hpd = <1>;
//dev1_output_type = <4>;
//dev1_output_mode = <10>;
//dev1_screen_id = <1>;
//dev1_do_hpd = <1>;
def_output_dev = <0>;
hdmi_mode_check = <1>;
fb0_format = <0>;
fb0_width = <0>;
fb0_height = <0>;
fb1_format = <0>;
fb1_width = <0>;
fb1_height = <0>;
chn_cfg_mode = <1>;
disp_para_zone = <1>;
/*VCC-LCD*/
/* dc1sw-supply = <®_dc1sw>;*/
/*VCC-DSI*/
/* eldo3-supply = <®_eldo3>;*/
/*VCC-PD*/
/* dcdc1-supply = <®_dcdc1>;*/
};
在SDK根目录下，烧写make、打包pack和烧录。即可在HDMI屏幕上显示。
2. 使能RTSP
进入目录：
cd /home/ubuntu/tina-d1-h/package/allwinner
新建文件support_rtsp.patch:
touch support_rtsp.patch
写入以下内容:
diff --git a/allwinner/tina_multimedia/libcedarx/libcore/parser/Makefile.am b/allwinner/tina_multimedia/libcedarx/libcore/parser/Makefile.am

用 git apply 来运行 patch 补丁:
git apply support_rtsp.patch
如果出现以下错误：
ubuntu@ubuntu1804:~/tina-d1-h/package/allwinner$ git apply support_rtsp.patch
error: patch failed: allwinner/tina_multimedia/libcedarx/libcore/parser/Makefile.am:72

ubuntu@ubuntu1804:~/tina-d1-h/package/allwinner$
大概率是被修改过了，不用再修改。
执行croot，进入配置界面：
make menuconfig
选上以下内容：
保存、编译make、打包pack和烧录。这样开发板就支持rtsp拉流功能了。
3. RTSP推流
有拉流，相应的就需要有推流。要实现这些功能，首先需要一个支持rtsp流媒体协议的服务器，可以在windows下搭建一个服务器。
下载链接：Releases · bluenviron/mediamtx (github.com)
下载完成后，双击.exe，即可运行服务器：
一般使用的是8554这个端口。
在ubuntu上，准备一个mp4格式的视频（视频尽量一分钟左右），使用ffmpeg工具来实现推流操作：
ffmpeg -re -stream_loop -1 -i input.mp4 -c copy -f rtsp rtsp://192.168.0.198:8554/input.mp4
192.168.0.198是windows上的无线ip地址。
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。
4. 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。
wifi配置、连接根据之前写的操作来执行。
tplayerdemo 来拉流播放：
操作之前需要先把windows上的防火墙关闭，确保能ping通192.168.0.198，同样也需要能ping通ubuntu的桥接ip地址。
tplayerdemo rtsp://192.168.0.198:8554/input.mp4
可以看到视频可以播放到 HDMI 的输出了，日志如下：
