Install:

Suppose that the piwigo have been installed at the dir of

PIWIGO_DIR=/opt/local/data/www/gallery,

wget -O piwigo-videojs.zip https://github.com/xbgmsharp/piwigo-videojs/archive/master.zip

unzip piwigo-videojs.zip

sudo mv    piwigo-videojs-master ${PIWIGO_DIR}/piwigo-videojs
sudo chown ${PHP_USER}  -R       ${PIWIGO_DIR}/piwigo-videojs
sudo chgrp ${PHP_GROUP} -R       ${PIWIGO_DIR}/piwigo-videojs

Customize bin path

Suppose that ffmpeg,mediainfo,exiftool,ffprobe have been installed at /opt/local/bin/

Add the following line into the file of ${PIWIGO_DIR}/include/config_default.inc.php

$conf['vjs_mediainfo_dir']='/opt/local/bin/';
$conf['vjs_exiftool_dir']='/opt/local/bin/';
$conf['vjs_ffprobe_dir']='/opt/local/bin/';
$conf['ffmpeg_dir']='/opt/local/bin/';

Update media info of your video

Go to the admin page of your gallery,

Select the album with video ,

Edit the album,

Manager the image of the album

Select video file

Play DSD dff file within MPD daemon

发表于由

To support play DSD dff file inrealtime mode, we must add dsdiff plugin in mpd config file.

crtmpserver配置文件详解

 

Configuration file

配置文件

 

The configuration file is actually a lua script which must contain an

object called configuration.

This will be read by the server and used to fully configure the server.

Besides this object called

configuration you can have functions, include other lua libraries, etc.

In the end, you have to

make the configuration object available. The rest of this section will

explain the structue of

configuration object in great detail. But first, let’s take an bird-eye

view.

 

配置文件实际上是一个Lua脚本，它包含至少一个configuration的对象，

从而为程序提供灵活的扩展和定制功能。

除了configuration对象外，还可以有函数，Lua库等。

 

 

Main structure

主结构

 

configuration=

{

daemon=false,

pathSeparator=”/”,

logAppenders=

{

— content removed for clarity

},

applications=

{

— content removed for clarity

}

}

 

configuration structure

key type    mandatory  description

daemon boolean    yes     true means the server will start in daemon mode.

false means it will start in console mode (nice for development)

true  表示 服务以后台方式启动;

false 表示 服务以控制台模式启动(以用于开发);

pathSeparator string(1) yes     This value will be used by the server to

compose paths (like media files paths).

Examples: on UNIX-like systems this is / while on windows is \.

Special care must be taken when you specify this values on windows

because \ is an escape sequence for lua so the value should be “\\”

用来分隔路径;

例如，在UNIX-like是 /, Windows是 \  ;

logAppenders   object yes     Will hold a collection of log appenders. Each

of log messages will pass through all the log appenders enumerated here.

More details below

配置日志追加的容器 <http://wiki.rtmpd.com/documentation#logappenders>

applications   object yes     Will hold a collection of loaded applications.

Besides that, it will also hold few other values. More detailsbelow

配置加载各种应用的容器 <http://wiki.rtmpd.com/documentation#applications>

 

When the server starts, the following sequence of operations is performed:

服务启动时，将按顺序执行下列操作:

 

1.

The configuration file is loaded. Part of the loading process, is

the verification.

If something is wrong with the syntax please read this

配置文件加载后，首先做的就是对配置文件进行校验，

如果配置文件有错误，将会有错误提示并停止启动，可进行修改后再启动

<http://wiki.rtmpd.com/faq#qi_run_server_but_it_silently_shutdown_what_is_wrong>

2.

daemon value is read. The server now will either fork to become daemon

or continue as is in console mode

读取 daemon 值，判断服务是以后台方式启动还是以控制台方式启动

3.

logAppenders is read. This is where all log appenders are configured

and brought up to running state.

Depending on the collection of your log appenders, you may (not) see

further log messages

读取日志追加器，用来配置日志记录并启动到运行状态，

依据日志追加器，可以看到更多的日志信息

4.

applications is taken into consideration. Up until now, the server

doesn’t do much.

After this stage completes, all the applications are fully

functional and the server is online and ready to do stuff

最后的应用加载，只到这一步完成后，服务和应用才在线，并准备就绪。

 

 

日志追加器

logAppenders

 

This section contains a list of log appenders. The entire collection of

appenders listed in this section

is loaded inside the logger at config-time. All log messages will be

than passed to all this log appenders.

Depending on the log level, an appender may (not) log the message.

“Logging” a message means “saving”

it on the specified “media” (in the example below we have a console

appender and a file).

这部分包含了一个日志追加器的列表。

整个日志追加器的添加是在加载时配置，

依据日志级别，追加器可以选择是否有日志消息输出到指定目的处；

logAppenders=

{

{

name=”console appender”,

type=”coloredConsole”,

level=6

},

{

name=”file appender”,

type=”file”,

level=6,

fileName=”/tmp/crtmpserver.log”

}

},

 

 

logAppenders structure

key type    mandatory  description

name    string yes     The name of the appender. Is usually used inside

pretty print routines

追加器的名字.

type    string yes     The type of the appender. It can

be console, coloredConsole or file. console and

coloredConsole will output to console. The difference between them is

that coloredConsole

will also apply a color to the message, depending on the log level.

Quite useful when eye-balling the console.

file log appender will output everything on the specified file

追加器的类型

可以是控制台，带颜色控制台或文件；

控制台和带颜色控制台 都会将日志消息输出到控制台，

不同之处在于带颜色控制台会依据日志级别进行颜色标记；

文件类型则会将所有消息输出到指定的文件；

level   number yes     The log level used. The values are presented just

below. Any message having having a log level

less or equal to this value will be logged. The rest are discarded.

Example: setting level to 0, will only log FATAL errors.

Setting it to 3, will only log FATAL, ERROR, WARNING and INFO

 

 

日志的级别

可见下表中的级别定义；

只有小于或等于这个级别的日志消息会被记录，高于这个级别则都被丢弃；

例如:

应用

Applications

 

This section is where all the applications inside the server are placed.

It holds the attributes of each application that the server will use to

launch them.

Each application may have specific attributes that it requires to

execute its own functionality.

这部分用来配置各种应用，并设置这些应用的属性；

每个应用的属性都对应了这个应用的指定功能；

rootDirectory=”applications”,

{

— settings for application 1

— content removed for clarity

},

{

— settings for application 2

— content removed for clarity

},

{

}

}

 

 

Applications Structure

key type    mandatory  description

rootDirectory string true    The folder containing applications

subfolders. If this path begins with a / or \ (depending on the OS),

than is treated as an absolute path. Otherwise is treated as a path

relative to the run-time directory

(the place where you started the server)

这个目录包含了应用的子目录；

如果路径以 / 或 \ 开始， 则视其为绝对路径，否则视为启动服务时所在的相对

路径；

 

Following the rootDirectory, there is a collection of applications. Each

application has

its properties contained in an object. See details below

rootDirectory 之后，是应用的集合；每个应用都定义了一个有特定属性的对象；

细节如下所示； <http://wiki.rtmpd.com/documentation#application_definition>

 

 

 

应用定义

Application Definition

 

This is where the settings of an application are defined. We will

present only the

settings common to all applications. Later on, we will also explain the

settings particular to certain

applications Since revision 790 there is a new cool feature:

mediaStorage; with this feature

basicaly an application may have multiple mediaFolder’s and .seek/.meta

files are now stored into

separate folder from media file that are streamed.

这些目录用来定义应用.

自从790版本后，添加了一新的功能：mediaStorage;

这个功能能使应用可以有多个mediaFolder，

并且可以将.seek/.meta文件和媒体文件分开存储在不同的文件夹中；

mediaStorage = {

namedStorage1={

description=”Main storage”,

mediaFolder=”/usr/main_storage/media”, — only this parameter IS

MANDATORY

metaFolder=”/usr/main_storage/metadata”, — if you have static

large file to stream it is good to know that for a file around 500MB

— it’s .seek file has

around 16MB; so it would be preffer to designate metafolder into a system

— partition which has

enough space… for no surprises… 🙂

statsFolder=”/usr/main_storage/statsFolder”,

enableStats=true,

clientSideBuffer=16,

keyframeSeek=false, — should crtmpdserver DO SEEK ONLY IN

key-frame (true/false)?

— very useful to know in situations like

play/pause/resume (meaning pause/seek/play)

seekGranularity=1,

generateMetaFiles=false,

renameBadFiles=false,

},

Application Structure

key type    mandatory  description

name    string yes     Name of application.

 

应用的名称

protocol   string yes     Type of application. The

value dynamiclinklibrary means the application is a shared library.

应用的类型

值为 dynamiclinklibrary 意即 应用是一个共享库

description    string no You can put a description of the application here.

应用的描述信息

default    boolean    no This flag designates the default application.

The default application is responsible in analyzing the connectrequest

and distribute the future connection to the correct application.

这个标志指定了默认应用；

默认应用负责分析连接请求并将连接分配到正确的应用

validateHandshake boolean    no Tells the server to validate the

client’s handshake before going further.

This is optional with a default value of true. If this is true and the

handshake fails,

the connection is dropped. If this is false, handshake validation will

not be enforced

and all the connections are accepted no matter if they are correctly

hand shaking or not.

通知服务器在进行下一步前要对客户端的握手进行验证；

这是一个可选项，其默认值为真。

如果这个值为真 且 握手失败，服务器就放弃这个连接。

如果这个值为假，则不会进行强制的握手验证，所有的连接都会被接受；

keyframeSeek   boolean    no This instructs the streamer to seek only on

key frames. In case of live streaming, this is discarded.

这个属性指定了流生成器只在关键帧搜索，

如果是直播流，则忽略这个值

seekGranularity    double no The seek resolution/granularity value in

seconds. Values are between 0.1 and 600.

For example, if granularity is 10 seconds, and a seek to t=2:34 is

desired, the seek

will actually go to t=2:30.

60seconds is recommended for full length movies and 1 second for video

clips.

搜索的精细度，以秒为单位, 值域定义在 0.1 ~ 600;

例如：

如果粒度定义为10秒，并期望定位到 t= 2:34;

则实际上是会定位到 t= 2:30.

60秒被认定为完整的电影长度，1秒为电影片断；

clientSideBuffer   double no The amount of client side buffer that will

be maintained for each connection.

Values are between 5 and30 seconds.

每个连接在客户端的缓冲秒数，值定义在5 ~ 30 秒；

generateMetaFiles boolean    no This will generate seek/meta files on

application startup.

在应用启动前生成 seek/meta文件

renameBadFiles boolean    no If this flag is true and the media file

can’t be parsed, the media file will be renamed to *.bad.

Otherwise it will be left alone.

如果这上值为真且媒体文件是不能被解析的，则媒体文件被重命名为 *.bad，

否则这样的文件将不做处理

aliases    object no The application will also be known by this name.

应用的别名

acceptors object no Acceptors hold the service that will be hosted to

the server. An application can have its own acceptor,

but this is not entirely required, and can be optional.

接受器保持这个服务并让服务器托管；

应用可以有它自己的接受器，但这个是可选的；

externalStreams    object no

authentication object no

mediaFolder    string yes     When define mediaStorage this field is

mandatory as it points out physical location of media files.

当定义了 mediaStorage时，这个域用来指定媒体文件的物理位置；

metaFolder string no It holds the location where .seek/.meta files

created from files inside mediaFolder are stored.

指定用来存放 .seek/.meta文件的位置；

statsFolder    string no Location for stats files.
