I know from the output of wget's log file you can see duration a url is downloaded in.
However I need to get the duration it takes for the streaming content.
Thanks
A file's a file's a file. Things like Youtube and the like work real hard to obscure where the actual URL comes from, though. The only even slightly reliable way I've found to figure that out is to set up your own proxy server, configure your web browser to use it, and watch the URLs it downloads for anything relevant. And even that sometimes doesn't work because when you try and download it by hand, you won't have the same cookies, etc.

NAME
NomNom - The graphical media download tool DESCRIPTION
NomNom is an application for downloading media from Youtube and other similar media websites that require flash to view the media content. Media streaming or downloading can be started by dropping an URL onto the application window. Project name The name of the application refers to the sound effect that is made when eating something tasty or nutritious. GETTING STARTED
Right-click opens the context-menu Most the application features can be accessed via this menu. Check the settings (Ctrl+E) NomNom will attempt to detect the available commands when you run it the first time. Going over the settings before use is recommended. The dialog will not close (by clicking OK) unless you have entered everything needed. Check that NomNom is set to do what you expect Make a note of the combobox widget on the main window. You may choose to either "Download" or "Stream" from the widget. Drop media page URLs to main window You could, for example, have a web browser open from which you then drag the URLs onto the main window of NomNom. Alternatively, open the right-click context-menu and choose "Address...". You may also consider making sure that NomNom stays on top of other windows if you are working on a small screen. There is an option for this in the application settings. NomNom defaults to resume interrupted transfers See also the "KNOWN ISSUES" for more about this. You can also choose to overwrite any existing media files if you'd prefer this. You can grab media page URLs from YouTube feeds Choose "Feed..." from the context-menu or hit the key-shortcut (Ctrl+F) to open the dialog. COMMAND LINE
NomNom supports the following command line options. --config-path Prints the path to the local user config file and exits. --locale Prints the system locale (as returned by Qt) and exits. --detect Prints the detected commands and exits. --verbose Turns on verbose output. Please make a note that NomNom must be configured and built with the "--enable-verbose" switch for this to be available in the application. --help Prints the help and exits. --version Prints the version and exits. GLOSSARY
Media page URL NomNom feasts on media page URLs. You can drop these URLs to the main window to start the process of downloading (or streaming). These URLs are known to go around also as "video page URLs". Example http://vimeo.com/1485507 Media stream URL Not to be confused with "Media page URL". The media stream URL is the URL to the media resource that is returned by the quvi(1) command and then used by NomNom to either download or stream from it. YouTube feeds NomNom can read, with the help of umph(1) command, and grab media URLs from YouTube feeds. These feeds may be playlists, user favorites and user uploads. You can open the user-interface by selecting it from the right-click context-menu ("Feed...") or by hitting the key-shortcut (Ctrl+F). YouTube format strings The YouTube "fmtNN" string IDs are documented at: http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs KNOWN ISSUES
Resuming partially transferred files may fail Some websites are known to refuse to work with the HTTP requests to resume a file transfer. Workaround Either check "Always overwrite existing media files" in the settings or remove the existing file manually. HTTP user-agent Some websites refuse to play nice with renegade user-agent strings. Recommendations Make sure both quvi(1) and curl(1) use the same user-agent string. Note that quvi(1) uses "Mozilla/5.0" by default. HTTP proxy Generally OK, although some proxies may have been configured to "cook up" the HTTP headers before they are sent back to the server. This may sometimes lead to issues with the servers. Recommendations If you use an HTTP proxy, make sure you have configured all of the commands that NomNom uses (e.g. quvi(1), curl(1), etc.) to use the same proxy. TIPS
Use configuration files Although it is possible to configure custom commands for NomNom to use (via "settings" and "commands"), another way is to add/edit the appropriate configuration files for these commands. Examples ~/.quvirc ;# refer to the quvi(1) documentation ~/.umphrc ;# refer to the umph(1) documentation ~/.curlrc ;# refer to the curl(1) documentation Same goes for whatever media player you choose to use with NomNom. FILES
Configuration file The location of this file may vary and depends on how Qt was configured. You can use the "--config-path" program option to print it. See also "COMMAND LINE". LICENSE
