Transcode MP3 to MP3, ONLY when bitrate > client maximum

Postby nothsa » Mon Sep 19, 2011 9:30 pm

I have everything set up and working great with Subsonic and my Android phone.

Now I am wanting to transcode my MP3s to lower quality MP3s to be sent to my phone. Here are the details.
  • My music collection has a wide variety of bitrates, ranging from 64kbps to 320kbps
  • I don't need anything higher than 160kbps on my phone, so I set the "Max Bitrate" to 160kbps on phone
  • When I try to play an MP3 file with a bitrate lower than 160kbps, I want Subsonic to just send the original file
  • When I try to play an MP3 file with a bitrate higher than 160kbps, I want Subsonic to transcode it to 160kbps
I looked around for answers to this question, but couldn't find anything about this specific problem. Can anyone tell me how to do this?

Just set the max bitrate for the player that the android app uses in settings/players to 160 and the jobs done.
DO NOT CHANGE the transcoding options from default unless you know what you are doing

BKKKPewsey: I'm comfortable changing codec options if that's what I have to do, but are you telling me that Subsonic already does the functionality that I'm wanting? I.e.

  • If the file is 64kbps, it will NOT transcode and upsample to 160kbps (it will just transfer the original file)
  • If the file is 160kbps, it will NOT transcode it to a new 160kbps stream (it will just transfer the original file)
  • If the file is 320kbps, it WILL transcode it and downsample to 160kbps

That is correct :)
Also don't forget bitrate is set in 2 places, player and settings/advanced for overall download/upload bitrate
