LinuxQuestions.org - Mplayer Keys/Keyboard Config

Hello, I have a bunch of questions about the ~/.mplayer/input.conf file. I could not find an mplayer specific forum, so I am posting here.

First I have some questions about specific syntax of the input.conf file:

1) How do you set a single letter key (for example, 'a' or 'l' or 'b') to do a command? I can have managed to make it use keys like RIGHT and LEFT but not single keys. Some simple example code would be much appreciated.
2) How do you specify a key with a modifier like CTRL or SHIFT? Is shift merely the uppercase letter used in the input.conf file?

Secondly, I would really get some help with determining the exact commands/syntax for the ~/.mplayer/input.conf file for certain actions. I know the help/man pages seem pretty explicit, but I'm still having trouble. I REALLY just need some examples of some of these commands in action.

Commands:

Code:

* Toggle loop playback on and off

* Cycle aspect ratios, or at least how to assign one to a specific key if cycling is not available

* Toggle window border on/off

* Zoom in/out

* Reset Video/Window size to original (source video size)

* Toggle interlace/deinterlace

Setting different keys for:

Code:

* Cycle through available internal subtitles (currently 'j' and 'b')

* Cycle through available internal audio tracks (currently '#' according to the man pages, but I cannot get it work)

* Volume increase/decrease (currently '9' and '0')

* Load file (currently 'l' in GUI mode)

Is it possible to do:

Code:

* Frame backwards and pause (similar to the key '.', but in reverse)

* Setting an A+B playback in the video

Disabling the following keys/features:

Code:

* contrast

* brightness

* hue

* saturation

I assume I could probably set the command to NULL or something, but I'm wondering if there is a better way
