Wow. I can't for the life of me figure out how to get this working. I've
tried a few things.
First, the transcoding rule in convert.conf appears to be wrong and gets
rejected. If you enable debugging (player.source) you'll see an error in
the server.log file.
The rule:
Code:
--------------------
aif mp3 * *
# IFB:{BITRATE=-B %B}D:{RESAMPLE=--resample %D}
[lame] --silent -q $QUALITY$ $RESAMPLE$ -v $BITRATE$ $FILE$ -
--------------------
The error:
Code:
--------------------
[12-07-22 14:25:16.6099] Slim::Player::TranscodingHelper::getConvertCommand2
(370) Rejecting [lame] --silent -q $QUALITY$ $RESAMPLE$ -v $BITRATE$ $FILE$ -
because required capability T not supported:
--------------------
That's easy enough to fix. You can create a custom-convert.conf file
containing
Code:
--------------------
aif mp3 * *
# IFB:{BITRATE=--abr %B}D:{RESAMPLE=--resample %D}T:{START=%t}U:{END=%t}
[lame] --silent -q $QUALITY$ $RESAMPLE$ -v $BITRATE$ $FILE$ -
--------------------
Then the server will use the rule, but it doesn't work.
Code:

--------------------
There are some other problems with this rule (as with all of the rules
for MP3 transcoding), although they're not the reason why this
fails.transcoding. The '-v" is equivalent to using LAME's VBR -V4
setting, which makes no sense when the user designates a desired
bitrate. If you set a bitrate like 256 or 320 you'll end up with
something a lot lower in quality.
Simplifying the rule for testing, I tried:
Code:
--------------------
aif mp3 * *
# IFB:{BITRATE=%B}D:{RESAMPLE=%D}T:{START=%t}U:{END=%t}
[lame] --silent -b 256 $FILE$ -
--------------------
Same failure.
The thing I can't understand is that the rule works perfectly fine from
either the command line or when on the right side of a pipe, such as
when transcoding FLAC to MP3.
Code:
--------------------
flc mp3 * *
# FB:{BITRATE=%B}T:{START=--skip=%t}U:{END=--until=%v}D:{RESAMPLE=%D}
[flac] -dcs $START$ $END$ -- $FILE$ | [lame] --silent -b 256 $RESAMPLE$
- -
--------------------
Code:
--------------------
C:\>lame.exe --silent -b 256 "01 Some File.aif"
--------------------
