Subsonic Forum

When the player bitrate limit is set to No Limit and Subsonic runs through the Transcoder chain (for example to transcode WAV using the default ffmpeg) it will set %b to 128.

This means when rate limit is set to:
- 32kbps limit = plays at 32kbps
- 128kbps limit = plays at 128kbps
- 320kbps limit = plays at 320kbps
- No limit = plays at 128kbps

What determines this 128kbps value and can it be set as an option?

I believe that's LAME's default value, and the one it will use if you don't specify a bitrate.

It is lame's default, but this is an issue where the bitrate of 128 is passed to lame/ffmpeg as an argument - overriding lame's default bitrate.
So an issue with Subsonic, nothing to do with lame or ffmpeg.
