OPPO BDP-80 96/24 flac transcoding ?

**pentatonic** · 12-21-2011, 08:30 AM

Hi all, first post but have been using Mezzmo for a few months. I setup mezzmo with the right profile for my player and everything works well, but for some reason when it's transcoding a 96/24 flac file the end result is only 48kHz, is this a limitation of the program, a setting that has skipped my searches. Love Mezzmo, after having tried many before it, but this is annoying me. Help please!

It's a device profile setting that can be changed manually (device profiles are just text files). Which device profile are you using?

My playback device is the Oppo BDP-80, right now it's set as device profile OPPO (LPCM) I also just noticed that it even transcodes my mp3s which I think are supported by the player (though I really can't tell for sure)

If you point me in the right direction, I would be much obliged sir

To edit the profile, please open up the OppoBDLPCM.prf file (to find its location see this thread: http://forum.conceiva.com/showthread...ofiles-located) in Notepad, then find the id="s16be" avcontainer in it and you'll see two sample rates there:

Code:

                                <samplingrate>48000</samplingrate>
                                <samplingrate>44100</samplingrate>

You can add a new one or change the 48000 to something else and give that a try. Please note that FFmpeg may fail to transcode, thus you'd want to have logging turned on (see this thread about logging: http://forum.conceiva.com/showthread...nostic-logging) and check the transcoding log if files don't play.

Alternatively, open up a support ticket and we'll do this for you (but it may take a bit longer than you doing it yourself).

I will try that, thanks. Also will it stream 5.1 96/24 wav files and transcode 5.1 flac files, I've never tried mind you but I'm new to mutlichannel lossless formats.

We should be able to transcode 5.1 FLAC files. Regarding streaming 5.1 WAV files - do you have such a file? If you do, can you please right-click on it and post the output of the "Get FFmpeg Information" command, so that I could check what it looks like technically?

I tried to change the profile but still only 48kHz. I do have a 5.1 wav file but have never played it as I don't have 5.1 on my studio pc and can't stream it nor can I stream 5.1 flac, they come out as stereo on my Oppo.

This is the info you're looking for

Thanks for the file info - if you turn transcoding off and try streaming it, does it play correctly on the Oppo? Also, if you just try playing from a USB on the Oppo, does it play?

Can you please show the change you've made to the profile? After changing it, you need to delete transcoded files and restart the server for the change to take effect.

Evrything plays now but all 5.1 files play fast forward for a reason that eludes me. But 96/24 files are fine.

These are the changes I made
