Subsonic Forum

Hi, new user here Absolutely loving Subsonic and iSub on my iPhone - it's revolutionary for me.

My first problem however seems to be with bit rates and transcoding. I have a mixed collection of mp3s and flacs.. and I don't want to be streaming out original bitrate flac files whatsoever. I set the max bit rate on iSub for wifi and 3G to be 160 and 128, and have tried other values, but the flac files seem to come down at their original bitrates

I haven't changed any of the default transcode settings - do I need to?

Cheers

What makes you thing that the flac files are coming down at their original bitrate? Your phone would not be able to play straight flac files, so they have to be getting transcoded somehow if they are playing at all, and I bet you will see that it is at the bitrate that you set...

It's definately saying the files playing on iSub are not the bitrates I set. One file (FLAC original) was 971kbps bitrate and the size that was shown (160MB for 6 songs) made sense for that size.

As you can see below, I play a flac file and it seems to convert it to PCM, but not then to mp3.

The semi-fix I've used for now to prevent me blowing my 3G data use is to block flac -> mp3 conversion for iSub in the Players menu.

ffmpeg converts from flac to wav then lame converts that to mp3 which is then streamed out.

Yeh I was aware of that. I wonder whether the problem is with the lame encode. There's no way it would generate a 37MB 5 minute mp3 :/

No! I doubt if it would so why do you think it does?
There is nothing in the log to suggest that it is

That's what I'm seeing on the iPhone. Look here's the screenshots..





Is that enough?

Btw here's the log from that playback.. clearly shows not encoding with lame after the ffmpeg decode and some lame errors.

Sooo.... any thoughts?

The now playing screen in your second screenshot always shows the bitrate of the original file, regardless of what it's being transcoded to. I'm not sure about the third screenshot though; but I suspect if you go to the "cached" tab it will show you the mp3 size instead.
