Hey all,

i want to force Plex to transcode every flac 24-Bit File to 16bit/48khz.

Can i do this with custom XML Profile ?
How to do this ?

I’ve tested now:
Create “Profiles” Directory under: “/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Profiles” and place “Plexamp.xml” to this directory:

<?xml version="1.0" encoding="utf-8"?>
<Client name="Plexamp">
  <!-- Author: CUSTOM -->
  <TranscodeTargets>
    <MusicProfile container="flac" codec="flac" />
  </TranscodeTargets>
  <DirectPlayProfiles>
    <MusicProfile container="mp4" codec="aac,mp3" />
    <MusicProfile container="mp3" codec="mp3,mp2" />
    <MusicProfile container="flac" codec="flac" />    
    <MusicProfile container="ogg" codec="vorbis" />
    <MusicProfile container="asf,wma" codec="wmav2" />
  </DirectPlayProfiles>
  <ContainerProfiles>
    <MusicContainer name="mp4">
      <Limitations>
        <Match name="part.optimizedForStreaming" value="1" isRequired="true" />
      </Limitations>
    </MusicContainer>
  </ContainerProfiles>
  <CodecProfiles>
    <MusicCodec name="*">
      <Limitations>
        <UpperBound name="audio.samplingRate" value="48000" />
        <LowerBound name="audio.samplingRate" value="8000" />
        <Match name="audio.samplingRate" list="8000|11025|16000|22050|24000|32000|44100|48000" />
        <UpperBound name="audio.channels" value="2" />
        <UpperBound name="audio.bitDepth" value="16" />
        <UpperBound name="audio.bitrate" value="1411" />
      </Limitations>
    </MusicCodec>
    <MusicCodec name="wmav2">
      <Limitations>
        <UpperBound name="audio.bitrate" value="355" />
      </Limitations>
    </MusicCodec>
    <MusicCodec name="vorbis">
      <Limitations>
        <UpperBound name="audio.bitrate" value="320" />
      </Limitations>
    </MusicCodec>
    <MusicCodec name="mp3">
      <Limitations>
        <LowerBound name="audio.samplingRate" value="16000" />
      </Limitations>
    </MusicCodec>
  </CodecProfiles>
</Client>

Restarted Plexmediaserver, and play 24-Bit Musik on Plexamp, but see no transcoding…

Any Ideas… .? :frowning:

I am pretty sure that a custom profile won’t work with Plexamp.
The question is: why are you trying to do this in the first place? Is it because your device will stutter when you serve it higher quality files, like e.g. 192/24?

Can anyone verify this, that a custom profile not work in Plexamp… ? :frowning:

The quality is better, if the files are in 16bit only, because my Speakers are only captible for 16bit.
But my library contains a lot of 24bit files, that i won’t convert… .

So what can I do to realize this ?
