** Valid categories:
$cat_ids
** Valid region IDs:
$region_ids
NOTE: Categories and region IDs are case sensitive!
[orderby, time, duration]'s values are also case sensitive!
** Playing videos
1. To stream the videos in other players, you need to change the
configuration file. Where it says 'video_player_selected', change it
to any player which is defined inside the 'video_players' tree.
2. lower_cache and lower_cache_min values are used when -l (--use-lower-cache)
is specified as argument, or if the resolution of a video is lower than 720p.
** Arguments
1. Almost all boolean arguments can be negated with a '--no-' prefix.
2. Arguments that require an ID/URL, you can specify more than one,
separated by whitespace (quoted), or separated by commas.
** More STDIN help:
1. ':r', ':return' will return to the previous section.
For example, if you search for playlists, then list a playlist
of videos, inserting ':r' will return back to the playlist results.
Also, for the previous page, you can insert ':b', but ':r' is faster!
2. "6" (quoted) or -V=6 will search for videos with the keyword '6'.
3. If a stdin option is followed by one or more digits, the equal sign,
which separates the option from value, can be omited.
For example:
:i2,4 is equivalent with :i=2,4
:d1-5 is equivalent with :d=1,2,3,4,5
:c10 is equivalent with :c=10
4. When more videos are selected to play, you can stop them by
pressing CTRL+C. $appname will return to the previous section.
5. For the option ':kregex', the valid keys are:
$valid_keys
6. Space inside the values of the STDIN options, can be either quoted
or backslashed.
For example:
:re=video\\ title == :re="video title"
7. ':anp' stands for the "Auto Next Page". How do we use it?
Well, let's search for some videos. Now, if we'd want to play
only the videos matched by a regex, we'd say :re="REGEX".
But, what if we'd want to play the videos from the next pages too?
In this case, ':anp' is your friend. Use it wisely!
** Closed-Captions
To get the closed-captions (subtitles) for videos, you need to install
the 'gcap' program. See: http://gcap.googlecode.com
After it is installed, put it into the configuration file as:
gcap => '/path/to/gcap'
