bs2b not detected #2271

Closed uwidev closed 9 years ago

uwidev commented 9 years ago 
F:\mpv --af=bs2b --no-config
Option af: bs2b doesn't exist.
Error parsing option af (option could not be parsed)
Setting command line option '--af=bs2b' failed.

Exiting... (Fatal error)

...is what I'm getting. The video does not play and I am currently using the latest 32 and 64 bit of mpv. Am I missing something, or is it a client side error?

I’m not building with libbs2b as it is pretty much worthless. I can add it if you really want it though.

uwidev commented 9 years ago

Before I ask for a build, I want to ask why it's worthless? Has it been replaced by something else?

wiiaboo commented 9 years ago

Makes a lot of difference for certain kind of music (jazz, mostly old recordings), but for most of audio is barely noticeable.

Example: without; mpv-bs2b cmoy; mpv-lavfi bs2b cmoy

Okay then, nevermind.

I don't know if I'd call it worthless. It's really a matter of personal taste. After trying it out a bit, I decided I personally didn't like it. It does however do what it's advertised to do. It makes it sound like it's coming from speakers when you're listening with headphones. I didn't like the way it messed with the EQ though.

The only alternative would be lavfi=[earwax] but it's as horrible as hrtf.

I'm trying to get the bs2b filter from libavfilter working, but either I don't understand the syntax or something's not working (probably the former).

mpv --af=lavfi=graph="bs2b=profile=jmeier" video.mkv 
Error parsing option af (option could not be parsed)
Setting command line option '--af=lavfi=graph=bs2b=profile=jmeier' failed.

libavfilter reports it is available: ... bs2b A->A Bauer stereo-to-binaural filter

ghost commented 9 years ago

Try mpv --af=lavfi=[bs2b=profile=jmeier] video.mkv (the shell is going to remove your ")

^Yes, that works. Thank you. I knew I was doing something wrong.

EDIT: Just looked at manpage and realized I didn't see the single quotes in the examples. :\
