[gentoo-user] [OT] Left/Right Channel as Mono in Mplayer

[gentoo-user] [OT] Left/Right Channel as Mono in Mplayer

[Ow Mun Heng]

Hi All,

	Got a few disks (Karaoke) which has this feature of left (with vocal)
right(Music Only). Commercial set-top DVD players can switch between
left and right channels with a click of a button and cycle through all
the options.

My question here is how can that be done in Mplayer/Linux?

I found that there is an option to play Left  / Right / Stereo using
mplayer, but the syntax is weird and cannot be switched on the fly.

the 2 ways are using PAN and channels.

eg:
mplayer filename -af channels=2:2:1:0:1:1
mplayer filename -af pan=2:1:1:0:0

Anyone knows how to do it on the fly? Keyboard shortcut keys?

you can assign any key to any action in mplayer.

Unfortunately, That's not entirely true.

According to the docs. The commands which can be mapped are gotten from
mplayer -input cmdlist 

and unfortunately, there's not -af channels=xxxxx etc.

If anyone else has a clue if it's really possible or otherwise. Please
do let me know.
