Mpeg Dash-Streaming
我正在撰写关于直播的论文.我使用ffmpeg,ngix服务器和rtmp模块以及Dash industry的dash.js.我通过ffmpeg开始流到服务器,并且用破折号播放,播放器运行良好,但是有一些问题.
如果mpd-dash播放列表仍然具有块t = 0,则播放器仅播放,因此每当用户请求播放器和* .mpd更新时,块t = 0播放器都不会运行.
我将* .mpd文件上传到Dash Validator并收到错误:“Schematron验证未成功 – DASH无效!”.但是玩家是由Nginx生成的 – rtmp模块而不是我.
在搜索了一些论坛后,我得到了一些信息,即Nginx-rtmp模块生成错误的短划线播放列表* .mpd Nginx rtmp module -bug,并且可能是该错误被修复并合并到github中的主人(我认为是Mered – report).但我尝试下载最新的Nginx和rtmp模块,播放器也播放不正确.
如果我玩2年前的dash.all.js版本:视频只播放好(播放结束)如果播放列表* .mpd中存在chunk t = 0,或播放器不播放(播放中间播放)
如果我玩dash.all.js持续版本:视频播放并停止播放或循环播放.
我真的需要一些帮助,我的截止日期即将到来.
这是我的Nginx配置(主配置):
rtmp {
server {
listen 1935;
ping 30s;
notify_method get;
chunk_size 4000;
allow play all;
application myapp {
live on;
dash on;
dash_path /tmp/dash;
hls on;
hls_cleanup on;
hls_sync 100ms;
hls_fragment 2s;
hls_path /tmp/hls;
allow play all;
}
}
}
and some others config:
location /hls {
# Serve HLS fragments
types {
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
}
root /tmp;
add_header Cache-Control no-cache;
add_header Access-Control-Allow-Origin *;
}
location /dash.js {
root /usr/share/Nginx/html;
}
location /streaminghls {
root /usr/share/Nginx/html;
}
location /dash {
# Serve DASH fragments
root /tmp;
add_header Access-Control-Allow-Origin *;
}
and in html player :
Hls play excellently but not dash. I tried changing dash config in Nginx config and C-source of rtmp-module with recompiling but not thing changed.
My mpd play list :
I really need help.
