Sensible-cinema is a program that allows you to do pre-programmed scene selection (i.e. "mute out" 
or "bleep out" scenes) on arbitrary media players like netflix online, vlc, etc.

Currently it takes as input a list of "skippable" scenes, and a player description.
It then tracks whichever player you are using, and mutes or blanks out the system appropriately, 
during the scenes specified.

It works out of the box with the hulu and VLC players on windows.  It isn't hard to 
add new players, and probably wouldn't be too hard to add more operating systems etc.

== How to Use ==

Start playing your movie in its respective player, then startup sensible-cinema from
the command line thus:

     C:\> jruby -S sensible-cinema

It prompts you for a scene descriptions file (ex: bambi.yml), 
and then for a player description file (ex: hulu_full_screen.yml).

Sensible-cinema will now run in a console window, screen tracking the player to monitor its position,
and react appropriately.

It is presumed that you'll then minimize the console window and proceed to enjoy the movie.

You'll know that it's working if, when you change the time of your player (ex: dragging it to a new spot 
in the playback), the screen output in sensible-cinema's console should change to match the new time.

== How to install ==

First you'll need to install jruby (in case you haven't already), from http://www.jruby.org
Make sure you check the box "add it to my path" or something similar to that.

Next install the gem by either opening up the command window or hitting windows+r (run) and typing

       C:\> jruby -S gem install sensible-cinema 

  it's jruby only currently (since jruby allows for proper thread concurrency, has an easy GUI, and feels actually sane on windows).
  It could theoretically be ported to MRI 1.9.2, if anybody wanted to do so.
  Also if anybody would be interested in porting this to Linux I'd be happy to collaborate.
  
You can test that it's installed by running it (see above) and selecting the "example_scene_list.yml", and 
choosing the hulu player.

It will proceed do a few "demo" mutes and blank outs.

== Programming Your Own Scene Descriptions File ==

To program sensible-cinema, you create a scene description list it can use.

A Program Description List (Edit Decision List--EDL) looks something like this example:

mutes:
  "01:00:00" : "01:01:02.5" # mute from exactly one hour to one hour, one minute, two seconds and a half will be muted.
blank_outs:
  "01:00:00" : "01:01:02.5" # also blank out (overlay with blank window) the same.

Here's one with more detail

http://github.com/rdp/sensible-cinema/blob/master/zamples/scene_lists/example_scene_list.yml

Basically your job is to save an appropriate file like that somewhere, 
then start sensible-cinema and instruct it to use your new file.

To create it, basically you notice something you want to add to the list, add it, then go back a few seconds 
in your media player, and it should now be muted/blanked out automatically.

So here is a way to create your scene descriptions file.

First create a new file 

The easiest way to do this is to start sensible-cinema, then instead of choosing an existing file,
"right click" on the existing file "example_scene_list.yml" and choose "Copy"
now right click below the list of files and choose "paste"
This will create the file "example_scene_list Copy.yml"
Right click on it, choose rename, and give it a better name.
Now "right click -> Open" to open it in an editor (recommend installing notepad++ and using that).
Note that you can edit this file *on the fly* while the player is editing.  It will catch 
changes as the file is saved and apply them.

Now select it for use in sensible-cinema (even though it's still blank).
Now "screen" your movie.  As you watch it, you're going to add scenes to 
that file, and then re-watch the scene to test your additions.

As you watch when you encounter a questionable scene, go back several seconds using your player's 
controls.  When you encounter it once again, track its beginning and ending time.  One way to do this
is to, just before and just after the scene, hit the space bar *in the sensible-cinema window*.  
Hitting the space bar outputs the current time.  If you hit it twice, once before and once after, 
you should now have two reasonably accurate "timestamps" displayed.
Add the beginning and end times to your scene description file (changes will be automatically picked up), 
then review your additions by rewinding your player and letting it play through the scene again.
It should now skip it (play it "sensibly").  If not, adjust your timestamps and try again.

Once you're done then you can contribute your scene descriptions file if desired, back to the project itself [1].

== FAQ ==

Q. Can I watch movies this way on my TV, not just on my computer?

A. Maybe.  Or possible not yet, depending on your current hardware.
   Currently you'll either need to attach your computer to your TV
   (buy some long cables, or a new graphics card that matches your cables, etc.) 
   or get some computer that you can move closer to the TV to do the same 
   (ex: buy a used older laptop with s-video out, use that, or a laptop with DVI/HDMI would
   work with an HDMI TV).  If you're really aggressive you could run an ethernet cable from your computer, as well [1].
   I'd be happy to do a linux port of sensible-cinema if anybody requests it, for use with 
   their dedicated TV computer.
   There has also been some work toward getting ones computer to stream "live" to your existing wii/ps3/xbox.
   Message me if you're interested in trying it out (testers wanted--plus I'll only work on it if there's demand)!   

Q. What movies does this work with?

A. Any that you program it for :) (Assuming the computer player is compatible, which most probably are.)

Q. What movies are freely available to watch online?

A. Not many are available free (hulu, youtube have a few). Netflix has quite a few with its default subscription.  
   You can of course use it with any existing DVD, or rent or borrow DVD's and watch them using sensible-cinema.

Q. Why does my mouse bounce up and down while sensible-cinema is going?

A. This enables your player to keep its on-screen time tracker, which in turn allows sensible-cinema to track where 
   you're at.  Message me if this bugs you too much and we'll see what we can do about it.

== Advanced Usage ==

You could specify the scene descriptions list and player list on the command-line, if you don't want to have
to pick them each time, like:

     C:\> jruby -S sensible-cinema scene_descriptions_list.yml player_description.yml

Also if you specify "test" for the scene descriptions file, it will pause 4s, take a snapshot of the player, then exit.
You can also specify -v or -t if you want to enable more verbose (chatty) output.

== Caveats ==

NB that "someone" will have to create a scene descriptions list, per DVD/online movie.
Unless it already exists, then "someone" already has, so you don't have to.  Fortunately
only one person has to do it, once, for everybody to benefit, and the editing process is fairly easy.

== Thanks ==

Thanks to Jarmo for the win32-screenshot gem, mini_magick gem authors, jruby guys, etc.  
The combination made programming this actually something of a pleasure.

The concept isn't too novel:

http://en.wikipedia.org/wiki/Linear_video_editing
http://imdb.com tends to have reasonably good lists of what occurs in movies (find a movie, click on "parent's guide" on the left).  Sometimes it even lists the time signatures for events (ex: "Labyrinth"  http://www.imdb.com/title/tt0047673/parentalguide) which you could use to translate into a sensible-cinema compatible list.
