mp3 > ogg Transcoding

[IceFreak2000]

I'd like to set up mp3 > ogg transcoding for my Android device to help reduce the bandwidth required when connecting over 3G, but I can't seem to get the settings right.

I'm running Subsonic 4.4 on Windows 2008, and have oggenc2 in the transcode folder.

I've tried using this two-step process:

Step 1:

Code: Select all

lame -S --decode %s -

Step 2:

Code: Select all

oggenc2 -Q -b %b -o - -

but this generates the following error in the log:

Code: Select all

Starting transcoder: [c:\subsonic\transcode\lame] [-S] [--decode] [C:\Music\Boards of Canada\Music Has the Right to Children\17 One Very Important Thought.mp3] [-]
Starting transcoder: [c:\subsonic\transcode\oggenc2] [-Q] [-b] [2147483647] [-o] [-] [-]
(c:\subsonic\transcode\oggenc2) Mode initialisation failed: invalid parameters for bitrate

Any clues as to what I'm doing wrong?

Many thanks

ffmpeg -i %s -f wav -

lame -b %b - -

Works on my Server 08 R2 install. Ther is a folder OGG Music on the server that uses these settings. Click Server link below for demo.

I think you've misunderstood what I'm asking Gary; I want to transcode to OGG from MP3

OK, I've just tried the following one-step transcode setting

Code: Select all

ffmpeg -v 0 -i %s -f ogg -vn -acodec libvorbis -ar 44100 -ab %bk -ac 2 -map_meta_data 0:0 -

that I found here http://forum.subsonic.org/forum/viewtopic.php?t=5121, but I'm getting the following in my log files:

So, something is up with the %b expansion for the 'ab' option; anyone seen this before?

My bad. Reminds me of the dyslexic Jew who was always walking around saying, "Yo."

This might be of some help:

[yourlord]

in all cases you are trying to transcode to a 2147483647Kbps stream which is pretty much absurdly invalid.

You need to track down how your requested bitrate is getting set to 2147483647..

Try changing the encoder line to force the bitrate to something like 128 or something and see if it transcodes. If it does, you can either hunt down how %b is getting replaced with a bogus value, or just live with the hard coded bitrates.
