@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

web管理后台实现原理
用nginx实现http服务器然后web前端就是经典html js 后端接口是C艹写的fcgi 后端通过json和udp把配置参数传给读帧编码推流程序tinyvisionIpc

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

前言
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

1080P20

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
感谢百问网和yuzuki大佬联合出品的TinyVision

ktv点歌机
一个触摸屏点歌
一个大屏播放视频

逸俊晨晖

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

逸俊晨晖

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

bad_apple.zip

逸俊晨晖

@houxiaoni
gst-launch-1.0 playbin file:/tmp/bad_apple.mp4 不行
换片源也不行

逸俊晨晖

@xiaowenge
是的

逸俊晨晖

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

逸俊晨晖

SDK1.01打上了最新的补丁
编译gst-omx报错

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
