之前做了个rtsp服务 拉流发现延迟比较高 实际上读帧和编码的耗时并有没那么高 所以猜测时rtsp服务带来了较高的延时 于是就做了个单独的udp传输264
测试结果 1080P@20 延迟100+ms
通信过程
tinyvision是服务端 PC是客户端
首先客户端向服务端发起连接请求 服务端回复视频参数
然后服务端向客户端持续发送264 客户端每次收到都必须回复顺序号 以此保证顺序同步 防止乱序和丢包导致的花屏
为了保证稳定性 服务端在根据客户端回复的顺序号判断出丢包后会小间隔进行多次重发 多次重发失败后判定为连接断开 客户端在大间隔没收到数据后会重新向服务端发起连接
PC端播放
PC端拿到264数据后 用ffmpeg解码获得yuv数据 然后用SDL间接调用openGL接收yuv数据进行渲染
@amirhos_esm 开发的过程中我也纠结过这个零拷贝问题 主要是这个h264编码器的输入必须要拷贝图像数据进去 不能直接传指针 也许还有传物理地址的办法 但是没找到 厂商还有一套商用sdk是支持零拷贝的 但是那是另一套框架 需要签NDA协议才能拿到 就是4.0的SDK

附件内容
安装包 整套程序的安装包 执行一个脚本就可以安装 本来打算用自解压脚本 后来发现在板子上解压不了 就直接用没压缩的
测试工具 ffmpeg mediamtx流媒体服务
镜像 和官方提供的镜像相比只是加了一些简单常用的命令进去
源码工程 读帧编码推流程序tinyvisionIpcV2 web后端接口程序tinyvisionFcgi
安装包安装
先用adb把安装包传入板子
adb push D:\Ubuntu18_tinyvision\share\setupTmp /root
cd /root/setupTmp
增加执行权限 执行安装脚本
chmod +x setup.sh
./setup.sh
等安装完毕后 修改启动脚本里的ip配置 以后开启都会自动配置ip
vi /etc/init.d/S98tinyvisionIpc
完成后重启
reboot
重要文件路径
开机启动脚本 /etc/init.d/S98tinyvisionIpc
主要程序 /root/
nginx程序 /www/server/nginx/sbin/nginx/nginx
nginx配置 /www/server/nginx/conf/nginx.conf
web /www/server/nginx/html
配置文件 /root/conf
录制路径 /root/record
功能测试
web管理后台
在pc浏览器上输入板子ip进入web管理后台
web每秒刷新板子资源占用状态 可以配置部分参数 注意 配置参数需要保存重启系统才生效
摄像机配置
验证过的参数
1920 1080 20
1280 720 30
640 480 30
rtsp server配置
可以配置url 和是否开启
用ffplay拉流验证
ffplay.exe -rtsp_transport tcp rtsp://192.168.2.17/live/1
rtmp server 和 http-flv server配置
可以配置是否开启 可以点击web video在web上观看摄像机画面
用ffplay拉流验证
ffplay.exe rtmp://192.168.2.17/live/1
ffplay.exe "http://192.168.2.17/flv?port=1935&app=live&stream=1"
rtsp push配置
可以配置rtsp推流url和是否开启
与rtsp服务不同的是 rtsp推流可以以rtsp的方式推流到外部的流媒体服务器
在pc用mediamtx.exe开启流媒体服务 只需双击执行程序即可 不需要任何配置 关闭窗口则结束流媒体服务程序
在rtsp推流配置url把ip换成pc的ip
rtsp推流只在程序开始运行时推流 如果当时流媒体服务没开启来则推流失败不再推流 所以必须先开启流媒体服务再给板子重启
rtmp push配置
与rtsp push配置同理
rtmp推流可以推流各种直播间
mp4 recorder
可以配置录制文件名 开启录制 查看录制文件
配置录制文件名不需要重启才生效 开启录制就生效
录制完成后 可以在record list查看、下载录制文件
拉流注意
拉rtmp和http-flv的延迟会比rtsp高
点击web video在web上观看摄像机画面是http-flv协议 所以延迟会高一些
最后发发牢骚
整套功能实现难度不大 但是调起来非常繁琐 一会写读帧编码推流程序 一会写后端接口fcgi程序 一会写html js 出来问题各个部分都要看一遍
最后还是一点一点调完了 64MB内存能跑这么多东西做完还是非常有成就感的

静谧里 它静静地守候 如同时间的拾荒者 捕捉着光影交织的故事
——致摄像机
演示效果
基本思路
用v4l2读取摄像头图像 然后用硬件编码器把图像编码 最后把编码数据传给rtsp服务器 这样外部就可以直接拉流播放了
提供的系统里有个摄像头测试程序camerademo 能用v4l2读取摄像头图像 sdk里有源码 把源码简单修改一下接口对接
提供的系统里有个硬件编码器测试程序encodertest 能把图像编码成h264数据 直接运行是不能使用的 它的参数解析有问题 需要修改源码的长宽和文件输入输出路径 重新编译才能使用
注意 sdk里面有多个编码器操作例子 只看到一个是接口符合sdk里面的编码器操作接口 其他都是不能用的老接口
能用的encodertest源码路径openwrt/package/allwinner/multimedia/tina_multimedia_demo/encodertest/mpp_src
rtsp部分是网上找的一个编程实现的简单的rtsp服务器 相当于推流加服务器 外部直接拉流就行

应用程序使用方法
先用adb把程序传进板子
adb push D:\Ubuntu18_tinyvision\share\app\tinyvisionIpcV1\tinyvisionIpcV1 /root
使用命令添加执行权限
chmod +x tinyvisionIpcV1
使用ifconfig配网
ifconfig eth0 192.168.2.17 broadcast 192.168.2.255 netmask 255.255.255.0 up
ifconfig lo 127.0.0.1 up
route add default gw 192.168.2.1
仅支持一种参数格式 参数为 长 宽 帧率
执行例子
./tinyvisionIpcV1 640 480 30
执行时不加参数时默认参数为 640 480 30
当参数不支持时v4l2会打印出不同的参数 不会自动调整为相近的适合参数
v4l2打印的帧率有时候不对 以程序每秒打印的摄像头帧率为准
验证过的参数
1920 1080 20
1280 720 30
640 480 30
摄像头读图像帧使用v4l2框架 输出格式是NV21 参数不支持基本上是摄像头不支持导致的
默认操作设备/dev/video0 使用前检查有没这个设备 接了摄像头 摄像头驱动加载成功基本都会有这个设备
可以使用系统自带的camerademo排查操作摄像头有没问题
编码器是用的sdk提供的硬编码 输入NV21输出H264
程序运行时会每秒打印编码帧率 这个帧率不是编码器最大帧率 是工作时的帧率 摄像头帧率低会导致编码器帧率低
可以使用系统自带的encodertest排查编码器有没问题
rtsp是网上找的一个编程实现的简单的rtsp服务器 相当于推流加服务器 外部直接拉流就行
rtsp端口为554 路径为/live
拉流流例子 ip要换成板子的ip
rtsp://192.168.2.17/live
ffmpeg拉流使用方法
在pc上解压ffmpeg压缩包 用cmd进入ffmpeg bin目录执行命令 记得换ip
ffplay.exe -rtsp_transport tcp rtsp://192.168.2.17/live
参数-rtsp_transport tcp的意思是以tcp的方式建立rtsp链接 不写默认是udp 用tcp可以减少丢包花屏情况
cmake工程编译使用方法
工程使用cmake构建
需要安装cmake
apt-get install cmake
需要修改CMakeLists.txt里指定的编译器路径和头文件库文件路径
然后在CMakeLists.txt所在路径执行一次命令
cmake .
产生makefile 然后执行
make
就可以产生应用程序
注意 sdk的gcc使用时要求导出变量STAGING_DIR
export STAGING_DIR="/root/tina-v853-open/out/v851se/tinyvision/openwrt/staging_dir/"
用编译sdk时的source build/envsetup.sh也行
预告
读图像编码 rtsp流服务 只是开始
因为编解码器接口变更 4.0mpp没有移植到5.0的原因 我看很多人眼馋5.0的rtsp流 所以先把这个功能简单的工程分享出来
在以后的版本中 还要做rtsp/rtmp推流外部服务器 rtmp流服务 mp4录制 等等等
因为rtmp流服务用nginx服务器 nginx本身还是个http服务器 所以还会顺带上web搭建 在web上播放视频 在web上展示配置板子状态 用C艹写web后端
这所有的一切 将在这个64M内存的芯片上实现
我们的征途是星辰大海
羁绊
起初 我是在一些技术群 看到tinyvision的宣传资料 想看看生态如何 但又没有看到相关的交流群
然后到百问网的群里碰运气问问情况 没想到百问网的世玉轩找到了我 解答了我的问题 还送了我一套板子 你这是干什么 真是太客气了
最后感谢前人的努力

使用这个命令播
gst-launch-1.0 playbin uri=file:///root/bad_apple.mp4
gstreamer播放会闪屏 特别是把音频调为HDMI输出时 基本次次播都闪 原来耳机座输出也会出现闪屏 但是概率会小很多 幅度也小
我在仔细对比0730补丁文件后 没有发现问题 于是我重新make clean make 发现可以正常播放了
以下是测试能正常播放的命令：
1.指定硬件解码器和fb元件的播放视频命令
gst-launch-1.0 filesrc location=bad_apple.mp4 ! qtdemux ! h264parse ! omxh264dec ! videoconvert ! sunxifbsink
2.自动寻找硬件解码器 指定fb元件的播放视频命令
gst-launch-1.0 filesrc location=bad_apple.mp4 ! qtdemux ! decodebin ! sunxifbsink
3.同时播放音视频的命令
gst-launch-1.0 filesrc location=bad_apple.mp4 ! qtdemux name=demux demux.audio_0 ! queue ! decodebin ! audioconvert ! audioresample ! alsasink demux.video_0 ! queue ! h264parse ! omxh264dec ! videoconvert ! videoscale ! sunxifbsink
最后感谢上面大佬的帮助
@houxiaoni 在 gstreamer播放失败 中说：
@lajuchenghui 把你的这个测试片源贴出来吧，我测试看看。不过，你那边如果playbin都不成功的话，感觉还是环境没有弄好，再仔细对比一下7月30号的补丁文件
首先我用这个命令测试fb 是正常的
gst-launch-1.0 videotestsrc ! fbdevsink
然后我用tplayerdemo 播放文件bad_apple.mp4 是正常的
GST_DEBUG=4 gst-launch-1.0 filesrc location=bad_apple.mp4 ! qtdemux ! avdec_h264 ! videoconvert ! fbdevsink
失败报错 此时黑屏

@ubuntu
这个0730补丁我打过了
里面一些源文件我对比了 发现确实是打上了
后面发现唯独package/multidedia/gst-omx/Makefile没变成打完补丁后的 然后我替换了补丁里面的 编译通过了
总之可以了
SDK1.01打上了最新的补丁
编译gst-omx报错
错误信息如下：

在文件out/d1-nezha/compile_dir/target/gst-omx-1.16.3/omx/Makefile 可以看到
这些变量 CC CCAS 被错误得指定为了gcc 其他文件的CC CCAS都是riscv64-unknown-linux-gnu-gcc 所以上面报了个gcc认不得-mcmodel=medany的错 实际上riscv是认得的
现在问题就是不知道哪里导致Makefile一些本该指定为riscv64-unknown-linux-gnu-gcc 指定为了gcc 当然在Makefile直接把gcc手动改为riscv64-unknown-linux-gnu-gcc也不行
