[Solved] Flac transcoding defaults to 128kbps

[yarbo]

I've recently started re-ripping a lot of my music collection as FLAC so that I have more freedom when streaming. For example, when streaming to work, I like 320kbps, cause I have the available bandwidth both at home and at the office. But when streaming to my Android, I limit the bandwidth to 192kbps, to preserve bandwidth.

However, when looking at the log, it seems to default to 128kbps when transocding flac to mp3 to stream to the office (when I'd rather it use 320kbps).

Here's my log:

Notice the ffmpeg command with [128k] as the listed bitrate....

Any idea how I can have it default to the highest bitrate, unless the player I am using specifically requests a lower bandwidth?

[BKKKPewsey]

Set the player you use to 320k rather then No Limit - its a bit of a weird default of ffmpeg.

[yarbo]

A large part of my music collection is still in V0 VBR mp3's - will setting the limit to 320kbps, cause lame to be used to "upscale" them, or will it just stream them as is?

And does transcoding a V0 VBR mp3 to 320kbps cause any "lossy compression" issues with the music?

[BKKKPewsey]

No it will not "upscale" them it will play at the max bitrate that it is encoded for a mp3 or for a flac it will downsample to 320k.

[yarbo]

Thanks again BKKKPewsey, you are truly a scholar and a gentleman. =D

[bass-style]

Having the same issue with No Limit is set in the player when transcoding from MIDI.
The problem is Subsonic sets the %b variable to 128 by default instead of leaving it blank.

[spookybathtub]

It would be great for the Subsonic devs to correct this, by using 320k as default or some other way.
