Here are the brief functions supported by EzStreamSvr:

• Video streaming: As an independent streaming/dispatching server, or as a relay for a remote RTSP/RTP video source.
• Video recording: Recording the videos while streaming, supports most of the popular file containers like MP4/FLV/AVI/MKV/TS.
• Video preview: Preview the videos on server while streaming to take advantage of in some specified solutions and user scenarios.
• Supports both RTP over UDP and RTP over TCP.
• Customized OSD for captured videos from Cameras on the server.

And because it's a standard RTSP/RTP streaming server, you can view the videos on any players which supports RTSP/RTP. This may make things a lot easier for you if you wants your video to be viewed on different client endpoints, no matter the OS of the endpoint is Windows, MacOS, Linux, Android or iOS, even Windows CE, Windows Mobile, Symbian can be supported too.

EzStreamSvr supports three type of video sourcer:
1. Video captured from the cameras(WebCam) on the Server.
Simply open your player using rtsp://IP_ADDRESS/live.sdp.
*IP_ADDRESS: Replace IP_ADDRESS with the real IP address of the EzStreamSvr
2. Video from standard RTSP/RTP based videos, like IP Camera.
Open a url like this, rtsp://IP_ADDRESS/relay.sdp?url=rtsp://113.196.162.124:554/user=admin&password=&channel=1&stream=0.sdp?real_stream
*IP_ADDRESS: Replace ip_addr with the real IP address of the EzStreamSvr
*url parameter string: rtsp://113.196.162.124:554/user=admin&password=&channel=1&stream=0.sdp?real_stream
- This url is could be difficult to understand if you are not expert at RTSP/RTP, let's put it in simple, it's the URL you need to input to open the stream direct from the video sourcer if you don't use EzStreamSvr.

3. Video from some popular None-RTSP/RTP DVRs, like Dahua and Hikvision.
Open the video from EzStreamSvr by using url like this, rtsp://IP_ADDRESS/dvr.sdp?ip=xxx.xxx.xxx.xxx&port=XXXX&channel=CHANNEL_NUMBER&user=USERID&pass=PASSWORD&devicelib=DEVICE_LIBRARY
*IP_ADDRESS: The IP address of your EzStreamSvr.
*xxx.xxx.xxx.xxx: The IP address of the DVR device.
*XXXX: The port of DVR device. Default port for Dahua device is 37777, and 8000 for Hikvision devices.
*CHANNEL_NUMBER: The channel number of the DVR, from 1 to the max channel number of device
*USERID: User ID for the DVR. Dahua and Hikvision devices' default user ID are both admin
*PASSWORD: Password for the DVR. Default password for both Dahua and Hikvision device are admin
*DEVICE_LIBRARY: Device library of the DVR. Supports two strings: DH for Dahua devices, HIK for Hikvision devices

By using EzStreamSvr, you can enlarge the live video clients to hundreds, thousands instead of limited 10 or even smaller clients supported by most of the IP Camera or DVR. And you can record the videos as you wish while streaming them to hundreds of clients.

And because it's a standard RTSP/RTP streaming server, you can view the videos on any players which supports RTSP/RTP. This may make things a lot easier for you if you wants your video to be viewed on different client endpoints, no matter the OS of the endpoint is Windows, MacOS, Linux, Android or iOS, even Windows CE, Windows Mobile, Symbian can be supported too.

Some Players with RTSP/RTP streaming supported

Here are a Standard Players list which passed my test:

• CorePlayer, which has releases for Windows Mobile, Symbian, iPhone, BlackBerry, etc. And here are some test installation of CorePlayer(BE NOTICED: some of the releases may not be licensed, you must not use it except for test only purpose)

  • CorePlayer for Windows Mobile: http://bbs.rg4.net/thread-856-1-1.html

  • CorePlayer for Win32: http://bbs.rg4.net/thread-6234-1-1.html

• RealPlayer Embedded (Nokia N73): RealPlayer is a standard embedded app on Nokia smartphones.
• VLC Player: http://www.videolan.org
• QuickTime Player Professional
• Android Player (An Android Player provided by HTC for HTC phones)
• Some other players.

目前EzStreamSvr可以同时Streaming音频和视频，且支持多个摄像头，及Dual Stream（多码流）功能，是同一个视频源在同一时间内既可以提供适合电脑观看的大解析度的高清的视频，又可以提供适合手机看的小解析度的低码流的视频。

支持功能简述：

• 视频分发：也可作为一个独立的分发服务器，来Relay某一远程的标准RTSP/RTP的视频源。
• 视频录制：在直播（包括Relay）视频的同时，也可以对视频进行录像（录制于EzStreamSvr服务器上）。支持各种主流的容器，如MP4/FLV/AVI/MKV/TS。
• 视频预览：在直播（包括Relay）视频的同时，可以在服务器上直接对视频进行预览播放。
• 支持RTP over UDP, RTP over TCP。
• OSD字幕：支持OSD filter字幕。
• 视频采集：采集服务器上的视频并进行视频直播（采集部分的多码流功能由于实际用处不大，于3.0版本之后暂停支持）

一、关于EzStreamSvr

这 是一个标准的、基于RTP的流媒体服务器，服务器端捕捉第一个USB摄像头的视频，并编码成H.264 or MPEG4的视频，并打包以RTP的协议发送给客户端，可以在任何支持标准RTP的Windows客户端、Linux客户端、Mac客户端、 Windows Mobile手机客户端、Symbian手机客户端浏览实时视频。

当然，理论上讲是可以支持上述的客户端，但我个人测试的有：

1. CorePlayer(包括PC版和各种CorePlayer所支持的手机版:Windows Mobile, Symbian, iPhone, BlackBerry, etc.)

a. CorePlayer – Windows Mobile 手机版：http://bbs.rg4.net/thread-856-1-1.html

b. CorePlayer – Win32版: http://bbs.rg4.net/thread-6234-1-1.html

2. RealPlayer Embedded版（Nokia N73）：诺基亚手机自带

3. VLC（PC版） ：http://www.videolan.org

4. QuickTime Player Professional（PC版）

5. Android Player (Android手机内置播放器)

相关软件可以在流媒体开发论坛下载到。

二、简易安装说明文档

1. Windows标准版：

2. Linux标准版：http://rg4.net/p/ezstreamsvr/EzStreamSvr.For.Linux.Deploy.Guide.doc

3. Windows DSS版安装说明及使用手册请浏览网页：http://rg4.net/archives/185.html或者直接下载完整文档：http://rg4.net/p/ezstreamsvr/EzStreamSvr.For.DSS.UserMannual.doc

三、支持功能

一） 采集实时视频并进行音视频直播

视频格式：MPEG-4, H.264

音频格式：AAC, G.711 PCM Alaw/G.711 PCM Mulaw

二）Relay远程的RTSP/RTP音视频流

由于许多设备端终的RTSP/RTP流限于设备的能力，无法进行对采集到的音视频进行大容量的并行分发（一般都最多只能支持5~10路的并发），EzStreamSvr提供了对此功能的扩展，它可以从设备终端接收音视频流，然后作为一个分发服务器，进行分发。

三）Relay非标准流为标准RTSP/RTP流

如：将大华、海康或者其他任意非标准的视频流转换成标准的RTSP/RTP流，以使PC、手机、平板电板等内置的标准流媒体播放器就可以直接浏览其视频，而再也不需要安装特定的客户端。其使用方法可参考贴子：http://rg4.net/archives/311.html

目前支持的格式有：

1. 视频格式：MPEG-4, H.264, Motion JPEG

2. 音频格式：AAC, G.711 PCM Alaw/G.711 PCM Mulaw

三）录像

将实时采集到的音视频，或者是Relay的音视频进行录像，支持录制的容器格式有：

• 1. AVI
• 2. MP4
• 3. FLV
• 4. MKV
• 5. MPEG2-TS流

EzStreamSvr已经可以支持三种模式的多媒体源：

1. 从服务器采集音视频，编码后进行分发、录像和实时浏览。
2. 从标准的RTSP/RTP/RTCP的流媒体源接入视频，并进行分发、录像和实时浏览。
3. 从诸如大华，未来也可以支持海康，等任何非标准的媒体源接入视频，并进行分发、录像和实时浏览。

与上述三种模式对应的命令分别为：

rtsp://127.0.0.1/live.sdp
rtsp://127.0.0.1/relay.sdp?url=rtsp://113.196.162.124:554/user=admin&password=&channel=1&stream=0.sdp?real_stream
rtsp://127.0.0.1/dvr.sdp?ip=222.220.17.22&port=37777&channel=1&user=admin&pass=admin&devicelib=DH
