[Merge] lp:~mycompostpile/cairo-dock-plug-ins-extras/YoutubeDl into lp:cairo-dock-plug-ins-extras

 

Brian has proposed merging lp:~mycompostpile/cairo-dock-plug-ins-extras/YoutubeDl into lp:cairo-dock-plug-ins-extras.

Requested reviews:
  Cairo-Dock Team (cairo-dock-team)

For more details, see:
https://code.launchpad.net/~mycompostpile/cairo-dock-plug-ins-extras/YoutubeDl/+merge/108080

Here is the updated YoutubeDl applet. It has been changed to use CDApplet and the pynotify initialization has been fixed.  I still have some things to do like allowing the youtube-dl update on right click and some documentation. It works pretty good although the communication via the queue is a little slow depending on your update frequency set in the YoutubeDl configuration. I use this quite regularly to grab short videos on Youtube and I also create a URL list of longer videos that I allow to download over night.

+This is an applet to Download Youtube videos
+
+Summary:
+This Youtube video downloader allows users to drag and drop video URLs onto the YoutubeDl icon and have the videos downloaded.
+
+This is a work in progress so feel free to report any bugs and/or suggestions.
+
+License:
+GPL, see COPYING.
+
+Details:
+This applet allows a user to drag Youtube links from the Youtube website and 
+drop them on the icon to download. The backend downloader is based on 
+youtube-dl.py.  If you have python-tk installed on your system saving and 
+loading url lists will be done using a graphical dialog box, otherwise you 
+need to set the directory path in the configuration and just enter the filename
+in the popup box.  If you have pynotify installed on your system you have the 
+option of letting the notification area of your desktop handle the alerts, 
+otherwise alerts will be done using the cairo-dock popup messages. You can 
+turn this feature on or off under the configuration.  Currently the url list 
+is not editable from the dock but if you save the list to a file you can edit 
+with a text editor then load the list back into the plugin. Downloading can 
+be paused from the context menu of the icon and you can choose to have 
+downloads start automatically in the configuration area.  The left click button
+on the mouse brings up the current url list and the middle button can be 
+configured for different actions.

+# A short description of the applet and how to use it.
+description = This applet allows a user to drag Youtube links from the Youtube website and drop them on the icon to download. The backend downloader is based on youtube-dl.py.\n\n If you have python-tk installed on your system saving and loading url lists will be done using a graphical dialog box, otherwise you need to set the directory path in the configuration and just enter the filename in the popup box.\n\n If you have pynotify installed on your system you have the option of letting the notification area of your desktop handle the alerts, otherwise alerts will be done using the cairo-dock popup messages. You can turn this feature on or off under the configuration.\n\nCurrently the url list is not editable from the dock but if you save the list to a file you can edit with a text editor then load the list back into the plugin. Downloading can be paused from the context menu of the icon and you can choose to have downloads start automatically in the configuration area.\n\nThe left click button on the mouse brings up the current url list and the middle button can be configured for different actions.\n\nPlease enjoy.

+    downloaderHelp ="""Download videos from youtube.com or other video platforms
+
+DESCRIPTION
+  Download videos from youtube.com or any other of the supported video platforms.
+
+Currently supported sites are: CollegeHumor, Comedy Central, Dailymotion, 
+Facebook, Metacafe, MyVideo, Photobucket, The Escapist, Vimeo, Yahoo!, YouTube, 
+blip.tv, depositfiles.com, video.google.com, xvideos, Soundcloud, InfoQ, 
+Mixcloud, OpenClassRoom.
+
+Many YouTube.com videos are in Flash Video format and their extension would
+be "flv". Other videos are encoded in H.264 and these usually have the
+extension "mp4".  In Linux and other unices, video players using a
+recent version of ffmpeg can play them. That includes MPlayer, VLC,
+xine, among others.
+
+OPTIONS
+  Update:   Update this program to the latest stable version.
+  Ignore Errors:  Ignore errors during download and continue processing.
+  Username:  Specify the youtube account username. Some videos require an
+          account to be downloaded, mostly because they're flagged as mature
+          content.
+  Password:  Like the username, specifies the account password.
+  Format:  Specify the video format (quality) in which to download the video.
+          For youtube.com, in particular, the meaning of the format codes is
+          given as:
+          WebM video at 480p: 43
+          WebM video at 720p: 45
+          H264 video in MP4 container at 480p: 18
+          H264 video in MP4 container at 720p: 22
+          H264 video in MP4 container at 1080p: 37
+          H264 video in FLV container at 360p: 34
+          H264 video in FLV container at 480p: 35
+          H263 video at 240p: 5
+          3GP video: 17
+
+          Note that not all videos are available in all formats and that
+          other sites supported by youtube-dl may have different conventions
+          for their video formats.
+  Max Quality:  Limit the maximum quality of the videos to download.
+  Title:  Use the title of the video in the file name used to download the
+          video.
+  No Overwrites:  Do no overwrite already existing files.
+
+  Continue:  Resume partially downloaded files.
+
+AUTHOR
+       youtube-dl was written by Ricardo Garcia Gonzalez and many contributors
+       from all around the internet.

+    pluginHelp = """     Youtube Download Applet 
+
+This applet allows a user to drag Youtube links from the Youtube website and 
+drop them on the icon to download. The backend downloader is based on 
+youtube-dl.py.  If you have python-tk installed on your system saving and 
+loading url lists will be done using a graphical dialog box, otherwise you 
+need to set the directory path in the configuration and just enter the filename
+in the popup box.  If you have pynotify installed on your system you have the 
+option of letting the notification area of your desktop handle the alerts, 
+otherwise alerts will be done using the cairo-dock popup messages. You can 
+turn this feature on or off under the configuration.  Currently the url list 
+is not editable from the dock but if you save the list to a file you can edit 
+with a text editor then load the list back into the plugin. Downloading can 
+be paused from the context menu of the icon and you can choose to have 
+downloads start automatically in the configuration area.  The left click button
+on the mouse brings up the current url list and the middle button can be 
+configured for different actions.

+
+	File downloader objects are the ones responsible of downloading the

+	program. As, given a video URL, the downloader doesn't know how to
+	extract all the needed information, task that InfoExtractors do, it
+	has to pass the URL to one of them.
+
+	For this, file downloader objects have a method that allows
+	InfoExtractors to be registered in a given order. When it is passed
+	a URL, the file downloader handles it to the first InfoExtractor it
+	finds that reports being able to handle it. The InfoExtractor extracts
+	all the information about the video or videos the URL refers to, and
+	asks the FileDownloader to process the video information, possibly
+	downloading the video.
+
+	File downloaders accept a lot of parameters. In order not to saturate
+	the object constructor with arguments, it receives a dictionary of
+	options instead. These options are available through the params
+	attribute for the InfoExtractors to use. The FileDownloader also
+	registers itself as the downloader in charge for the InfoExtractors
+	that are added to it, so this is a "mutual registration".
+
+	Available options:
+
+	username:         Username for authentication purposes.
