Using the VST plug-in as the last item in the stack of DSP options, the insertion of the DL plug-in runs fine via USB output.  However, if I set it up as a DSP option for network (DLNA) output to the same DAC, JRiver abruptly closes.  I have had it work for short intervals of a few seconds but the crash seems to be inevitable.  The network (DLNA) output works fine otherwise.

Is there something I should look into. 

P.S.:  I have the same experience with MC28.

[whoareyou]

Unfortunately I can't help solve, but I can confirm issue with VST2 plugin to an Oppo 205 over network / DLNA. 
At times it would seem as though it was working, and then JRiver would crash or communication would just fail.
Restarting JRiver would usually temporarily correct issue.

I finally gave up as it was not reliable / couldn't solve.   

Without Dirac the Oppo was very reliable.

[kr4]

I am still wrestling with this and have attached crash and log files. 

[Matt]

I just tried Dirac again and it's working for me with DLNA.  The crash is in the VST code.  Could you try different presets maybe?  A coming build will make the buffer size adjustable which could also matter?

[Matt]

I noticed the crashes are from 27.  Please switch to the latest 28.  Thanks.

Do you think it strange that, if the crash is in the VST code, that the same presets work on the same MC installation when using USB output?

FWIW, all my presets are for a 5.3 or 5.1 channel configuration but the crash occurs with even a stereo source.

I noticed the crashes are from 27.  Please switch to the latest 28.  Thanks.

I have done both 27 and 28 and on two different PCs.  Consistent crashes with Dirac/VST/DLNA.

[Matt]

You could try switching the buffer sizes with the latest MC28.  Restart between switches because of how we load the buffer size.

I'm kind of grasping at straws because it's unfortunately working for me.

Thanks.

Thanks.  Me, too.

Now, with the latest version of 28, I am no longer getting crashes but the VST is not being applied.  Can you tell me where I find this buffer size setting?

[Matt]

There is a search window at the bottom of the options page.  Search for VST.

[kr4]

Thanks.  I would never have thought to look there.
Anyway, quadrupling the buffer did not have any effect.  Still says "output doesn't support processing" and Dirac is bypassed.

[JimH]

Have you ever tried the 32 bit version of MC?

[Matt]

Anyway, quadrupling the buffer did not have any effect.  Still says "output doesn't support processing" and Dirac is bypassed.

If it says that, I think you're not sending audio in a way that MC can process.  Make sure you're converting to WAV.

[kr4]

If it says that, I think you're not sending audio in a way that MC can process.  Make sure you're converting to WAV.

It is sending PCM =or<24/192.   It is the same DSPStudio "Output Format" settings as used for and works for USB output.

[Matt]

You might add a new server.

Set the format to PCM 24-bit.

In DSP Studio, turn on only DiracLiveProcessor.

That's what I've done and it's working for me.

Thanks.

[Matt]

I'm playing an APE file which needs conversion.  Make sure you do similar.

[kr4]

That's what I've done and it's working for me.

That's exactly what I do except for "Output Format" where I downsample stuff that's too hi-res and Channels = 5.1.  However, if I change channels to "Same as input" or simply bypass "Out Format" completely, it still does not work.

I'm playing an APE file which needs conversion.  Make sure you do similar.

Conversion to ?  I am playing only PCM/FLAC as PCM.

[jimwallen]

It is sending PCM =or<24/192.   It is the same DSPStudio "Output Format" settings as used for and works for USB output.

The newest version 39 works great with DIRAC for me. I use an internal hard drive and use DIRAC only in DSP Studio, and plugged in with VST3 and the highest buffer rate.

[Matt]

Maybe try an APE in case your server supports FLAC so doesn't convert?

[Matt]

Make sure you pick "Specified output format" from the Audio > Mode.

[kr4]

All file formats?

[kr4]

I will make an APE file to try that but I do not understand it.  Are you saying something relevant to the options on which format are to be converted?
I usually pick all.

Make sure you pick "Specified output format" from the Audio > Mode.

Of course.

[kr4]

Same results with the APE file. ?

[Matt]

Does it appear in Audio Path?  How about trying something like the equalizer?

[kr4]

Does it appear in Audio Path? 

Yes, it appears in Audio Path.

How about trying something like the equalizer?

I inserted Equalizer before Dirac and Room Correction after Dirac.  All show in Audio Path in the stated order but Dirac still does not work while the others do.

[Matt]

I just tried to listen to Dirac (I was only checking Audio Path before).

It was applying the effect.

Maybe you don't have an effect loaded in DSP Studio properly?

[Matt]

Make sure you right click your Oppo zone and point it to the right server.

[kr4]

Maybe you don't have an effect loaded in DSP Studio properly?

Same VST and "effects" that work with the USB output zone.

Make sure you right click your Oppo zone and point it to the right server.

Yup but the zone is "s88 LAN" which I associate with DLNA Server "Oppo."

[Matt]

I'll send you a test build tonight.  We have one idea.

Thanks.

[jimwallen]

All file formats?

Mostly FLAC, WAV, MP4

[kr4]

I'll send you a test build tonight.  We have one idea.

Thanks but I am afraid that it did not help on my main machine nor on another that tried. 

From all of this, it seems likely that there is some setting that I have made (unintentionally or intentionally for another reason) that is interfering with this particular operation but I do not know how to ferret it out.  Are there files, back-ups or screen grabs that I can submit to enable this?

[bob]

This mostly works for me over DLNA with a Mac.
It does occasionally crash. The crash is IN the Dirac plugin.

I tested to a local zone, an Id and my Oppo 103.

I'm using the Audiophile 24 Bit Dac template for the DLNA server.
Set the DSP studio in there to use the Dirac plugin.
Put in a test filter that makes the sound obviously bad.
Right click on my Oppo zone, choose DLNA Controller options and Associate that Oppo zone with the Audiophile 24 Bit Dac DLNA server.

My audio path works for the most part, but not always, but the effect is applied every time.

Attached is a playback screenshot. Also the crash info in case that does anyone that writes that plugin any good.
