開始提出MPEG_DASH  dynamic adaptive streaming over http

DASH——RTMP(flash)——HLS(Apple,用於移動端較多)——HDS(Adobe)——MSS(微軟)自適應位元速率

flv,mp4,3gpp/mp4(dash),mpeg-ts(hls)

dash：一個mpd檔案和檔案片段

開發語言：js

開發工具：Node.js       (tibao 說他們開發H5用的webstorm啊)

node及npm安裝：

http://nodejs.org/download/ 下載安裝檔案

在mac上下載pkg檔案

node及npm解除安裝：（mac）

---------------------------------------
Mac OSX

1. 刪除/usr/local/lib中的所有node和node_modules
2. 刪除/usr/local/lib中的所有node和node_modules的資料夾
3. 如果是從brew安裝的, 執行brew uninstall node
4. 檢查~/中所有的local, lib或者include資料夾, 刪除裡面所有node和node_modules
5. 在/usr/local/bin中, 刪除所有node的可執行檔案
6. 最後執行以下程式碼:(可能具體安裝路徑會有區別 ,find ~ -name "node"   可以找到所有

sudo rm /usr/local/bin/npm
sudo rm /usr/local/share/man/man1/node.1
sudo rm /usr/local/lib/dtrace/node.d
sudo rm -rf ~/.npm
sudo rm -rf ~/.node-gyp
sudo rm /opt/local/bin/node
sudo rm /opt/local/include/node
sudo rm -rf /opt/local/lib/node_modules
 

---------------------------------------
Linux

1. 如果是apt-get安裝的, 直接

sudo apt-get remove nodejs

2. 如果不是:

rm -r bin/node bin/node-waf include/node lib/node lib/pkgconfig/nodejs.pc share/man/man1/node.1

(為什麼這裡一設定程式碼格式所有內容就消失...)

操作步驟：

1.      cmd調出Dos命令列

檢驗node –v

    npm -v

2.      輸入：npm install –g grunt –cli

此時會安裝grunt，應該會在環境變數中新增全域性變數，grunt命令不被識別

將npm安裝目錄下的node_modules資料夾、grunt、grunt.cmd複製到工作目錄

3.      輸入：npm install

必須要有package.json和GruntFile.js檔案

輸入：npm install grunt-contrib-watch

      npm installgrunt-contrib-jshint

      npm installgrunt-contrib-uglify

貌似有網路錯誤，重新輸入命令安裝即可

      npm installgrunt-contrib-qunit  (這個要安裝比較久)

      npm installgrunt-contrib-concat

      npm installgrunt-contrib-clean

      npm installgrunt-contrib-copy

      npm installgrunt-contrib-cssmin (下載了所有標註星號的)

      npm installgrunt-contrib-connect  安裝這個居然出現了不斷刷屏的ERROR LOG，後來提示Callback called more than once. 停止刷屏後重新安裝即可

-------------------分割線，以上是看dash開源專案，並沒有部署成功-----------------------

後來下載了bemTV的hlsp2p開源專案，決定一定要看下，額，又是NodeJS

1.npm install下載錯誤

2.安裝在D盤的nodeJS依賴庫，在E盤可以使用嗎？？？？？？？暫時不知道

3. 直接執行npm test，提示gulp不是內部或外部命令，額，好吧，我並沒有安裝gulp

     npm install -g gulp   全域性安裝gulp

    在指定專案目錄下區域性安裝gulp， npm install gulp

    然而仍舊提示“gulp不是內部或外部命令”

    命令列輸入“npm root -g"   ，輸出        C:\Users\dell\AppData\Roaming\npm\node_modules

    已設定使用者環境變數中的PATH=C:\Users\dell\AppData\Roaming\npm\node_modules,NODE_PATH=C:\Users\dell\AppData\Roaming\npm\node_modules

    系統環境變數中的Path  =D:\Program Files\nodejs

   為神馬？？？

4.改換mac osx

  需要使用sudo安裝命令，否則會提示許可權錯誤

 直接輸入npm install會提示出錯，error: no member named "Use" in namespace....之類的錯誤

  需要使用最新的npm版本，安裝命令為 sudo npm install npm-check-updates -g

-----------------------------problems

1.mac上編譯提示缺少underscore模組，但實際上存在啊

Uncaught Error: Cannot find module 'underscore'
