[MPlayer-dev-eng] [PATCH] volume control with ao_sdl

[Anders Johansson]

Hi,

We should auto-detect format, resampling and volume control, possibly
even 4 ch stereo and AC3 pass-through. Also I want to make the plugins
reentrant. I was planning to solve these issues in the new audio
plugin layer. Alex Beregszaszi volunteered to help me (I have tried
myself but I don't understand the code in libmpcodecs) unfortunately
he ran out of time. If anyone else is interested in helping me please
send me a mail, I have a preliminary design I just need help to
integrate it.

An other issue. I have begun implementing a graphic equalizer how
should the interface look? This is my idea:


-------------------
| | | | | | | | | | 
| = | | | | | | | |
| | = | | | | | | |
= | | = | | | | | |
| | | | | | | | | |
| | | | | | | | | |
--------=----------
| | | | | = | | = = 
| | | | | | = = | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
| | | | | | | | | |
-------------------

Press a button to get the above picture and then use the <- and ->
arrow buttons to move between the frequency bands and the up down
arrow buttons to change the settings. Please give me comments on this.
Also if anyone is familiar with the OSD I will be happy for any help.

Cheers,
//Anders
