[MPlayer-users] Keeping volume between audio tracks

[Vláďa]

Hello,

I've written a music player which uses MPlayer as a backend. But there 
is one major problem I still can't solve. MPlayer resets volume to 
maximum before each new track. I searched the internet for hours and 
tried many different suggestions but without any success.

I'd like to use the -af volume filter, because I can set the volume in 
dB here. AFAIK there are 2 ways to set the volume to a new value:
1) af_switch volume=XX
2) af_cmdline volume XX

Both of them work if a track is playing, but the volume is reset back to 
0 when a new track starts.

How can I set volume before playback starts? Thank you.
