#174 Transcoding from FLAC to mp3 cuts out at 60%

[Anonymous]

6.0.beta1 transcoding from FLAC to mp3 cuts out at 60% consistently. Songs show full length until added to player, then show as 60% of expected length. Problem is resolved by downgrading to 5.3

Can you please let me know which browser(s) this happens in?
Also, what setting do you have in Settings > Transcoding > mp3 audio?

It would be great if you could send me an example flac file which exhibits this problem. (My flac sample files work ok).

Thanks

Same thing for me.
I use this in Transcoding for Step 1: ffmpeg -i %s -map 0:0 -ab 320k -f mp3 -
and using also the same for "Downsample command".

I'm using Chrome Version 48.0.2564.109 (64-bit) on a Mac. I'm running Subsonic in a debian:wheezy Docker container (hosted on debian jessie). Here is my transcode for flac:
ffmpeg -i %s -map 0:0 -b:a 320k -v 0 -f mp3 -

This happens to all my flac files, but here's an example: https://www.dropbox.com/s/vi6wp40tpskin61/01%20-%20%27%272112%27%27.flac?dl=0

Nice song - haven't listened to it for many years :)

If figured it out. If you change "320k" to the (default) "%bk" it works. (The reason for this is that the server estimates the content length based on the default bitrate 192k. When it's actually encoded with 320k there will be a mismatch).

In the next version I can change the default from 192k to 320k to improve audio quality.

Thanks for the thorough bug report!
