MPEG Layer II audio decoder with multi-channel support
There is no maintainer for this port. Any concerns regarding this port should be directed to the FreeBSD Ports mailing list via ports@FreeBSD.org Port Added: 23 Apr 2003 21:22:20 License: not specified in port
A multi-channel MPEG encoder, using the ISO13818 standard and the dist10
source code. Multi-channel files may have up to 6 defined channels:
Left(L), Right(R), Center(C), Left Surround (LS), Right Surround (RS) and
a Low Frequency Enhancement channel (LFE).
ISO13818 defines 5 multi-channel modes (on top of the normal stereo mode),
each of these modes may have an optional LFE channel:
3/2: L, R, C, LS, RS
3/1: L, R, C, mono surround
2/2: L, R, LS, RS
2/1: L, R, mono surround
3/0: L, R, C
The "standard" surround sound encoding of "5.1 channels" is achieved by
using mode 3/2 plus an LFE channel.
A multi-channel MPEG file should decode OK on any MPEG decoder. If the
decoder doesn't recognize the multi-channel extensions, then you'll just
get a stereo file containing a down mix of the 5 channels.
Convert audio from USE_GMAKE to USES=gmake
- Trim headers
- Convert some USE_GNOME=pkgconfig to USES=pkgconfig
- Add some missing pkgconf dependencies
- Convert some USE_GNOME=gnomehack to USES=pathfix
Synchronize mctoolame-decoder and mctoolame-encoder. These ports are pretty
much mimic each other, so it probably makes sense to merge them into one, or
turn into master-slave pair. While here, replace unsafe gets() with fgets().
