Subsonic Forum

Hello All,

I put some FLAC files on my server just to see how Subsonic would handle the Transcoding. All seems fine except the files are transcoded to 128Kb/s even though no limit is set.

Does Lame have a max bit rate setting of 128Kb/s for FLAC files?

Hi,

there is no max-bitrate specific to FLAC file transcodes, but you should look into the Transcoding tab and see what kind of transcode command you have activated there. I have no trouble transcoding to 320kbps, although I am still hoping that some day a fix will come along that would allow lossless playback... .

But yeah, just post what you have set up and I'm sure it can be fixed.

Here are my FLAC settings:

flac > mp3 flac mp3 flac -c -s -d %s lame -b %b - -

Thanks for your last reply
Alan.

From what I have read the %b is the bit rate, and I assumed that bit rate would be either the assigned user bit rate or the transcoder max bit rate.

Alan.

For step2, try:

Code: Select all

lame -b 192 - -

You can exchange 192 with anything up to 320.

Thanks FF, I will try that.

But am I correct in thinking that.

If you have no bitrate limit it should stream in it's native bit rate.
If you have a bitrate limit, it should stream at the specified limit?

Best Regards,
Alan.

I am not sure what you mean by "native bit rate" - you need to specify the bitrate in the transcode command or otherwise I would guess it will just do 128kbps coming from FLAC. The max-bitrate setting in the user-specific settings only applies if you're streaming mp3 files directly. Those will get transcoded to a lower bitrate using the command specified in the "Advanced" tab, but I do not believe it applies to FLAC transcodes. Correct me if I'm wrong.

Ok, thanks flacflac,

I just assumed that if specified, the users bit rate was passed to the encoder via the %b parameter

Silly me.

Alan.
