Now this is downright weird: as a workaround for the "tearing" bug I decided to use gl2 output for now. Which works perfectly fine. Got a fast CPU, no problem. Now I wanted to limit the dynamic range and chainloaded two LADSPA plugins into my alsa setup (.asoundrc below).
dts tracks now are watchable at night without waking the neighbors, but when I
use *this* alsa device I can pass gl, gl2, whatever: the video output stays
dark.
I can only think of that it has to do with some A/V syncing method, but
seriously - I am bereft of proper clues.
Here is the ~/.asoundrc , I load the chain with mplayer -ao \
alsa:device=ladcomp
pcm.ladcomp {
type plug
slave.pcm "ladcomp_compressor";
}
pcm.ladcomp_compressor {
type ladspa
slave.pcm "ladcomp_limiter";
path "/usr/lib/ladspa";
plugins [
{
label dysonCompress
input {
#peak limit, release time, fast ratio, ratio
controls [0 1 0.5 0.99]
}
}
]
}
pcm.ladcomp_limiter {
type ladspa
slave.pcm "plughw:0,0";
path "/usr/lib/ladspa";
plugins [
{
label fastLookaheadLimiter
input {
#InputGain(Db) -20 -> +20 ; Limit (db) -20 -> 0 ; Release time
(s) 0.01 -> 2
controls [ 20 0 0.8 ]
}
}
]
}
