Hqplayer4 Remote HQPDcontrol v4

[Schafheide]

@Ales ProchazkaFirst may I say that I do like your ap!  Maybe it should be a compulsory addition to HQPlayer!

Can I ask for a possible addition to your ap ?

It is great that the colours of PCM & DSD files are different.  But, would it be possible to also have different colours for the different PCM files and the different DSD files ??  Maybe a big ask  ??

We all appreciate your work.

Are you aware that you could use a filter for that? In upper right corner …

.

there should be roughly 20 different colors … quite impossible to remember the right color/file bit depth sample rate association 

[Schafheide]

That was easy! Thank you.

Since HQPlayer has been updated to V4.22 the earlier issue with special characters (´`& etc.) is back (see attachment).

Any chance to fix this again in HQPDcontrol?

Would be cool - many thanks in advance!

 

FYI: @Miska

@copy_of_a Are you on a Mac and using Ventura?

Just curious because Audirvana have trouble also with users using accents letters.

I fixed a related issue one or two days after the release on macOS. If this was downloaded right after the release, please download the installation package again and update the application.

Unfortunately the issue still persists with the new download.

I've discovered another issue which is related: albums with certain special characters can't be deleted from the library.

When I try to delete for instance an "Arvo Pärt" album, the column in the library will be deleted for that moment; but when I close and reopen the library, the respective album is still there. So obviously still an issue on HQPlayers side, not HQPDcontrol.

this is unrelated. Basically HQP / HQPDcontrol can show almost all special characters, at least on Mac and iOS.

Items are deleted based on the file system path. So if you have special characters there, it may lead to issues. Metadata is another matter and there it doesn't cause such problems.

 

Issue with for example ä in paths is that there are two ways to represent same character in Unicode. It has a specific character code in the character set, but in addition it can be presented with a+umlaut combination of two characters. These two don't compare the same, even though they look the same on display.

thanks, Miska.

However, I've never experienced issues with special characters also in file paths. It first showed up in the latest release of HQPDesktop.

@Ales Prochazka hi Ales, just installed the last HQPDControl update (iPad 5/iPadOS 16.5) but spectrogram page is blank … does it work with HQPlayer embedded v.5 (OS) too?

Hi Stefano,

Yes. I use iPad and HQPE5.
But the spectrogram only works on PCM sources.

That’s it! I was trying playing DSD …

thank you

It works for both, but for optimization reasons you need to enable matrix processor in HQPlayer for it to appear for DSD sources as well. I didn't want to add it to the non-matrix DSP path because it would have had CPU load implications there, and I wanted to keep that path as low CPU usage as possible for less powerful hardware.

Hi Ales,

 

I had hopes the new spectrogram feature could be incorporated into HQPD Control.

Any chance you can also built in the metering? Would be super handy (and for me personally much more important than the spectrogram during playback).

 

Many thanks for this great remote!!

Hi,

Well, it should be there...

Yes, I do see it and the spectrogram is working as supposed to.

Sorry for the confusion - I was referring to the level metering (see screenshot from Client).

Next step.
I wanted to release at least a spectrogram display, because someone wanted it for the sake of checking for fake HiRes recordings. The levels didn't seem that important to me.

well, we could enjoy HQP and HPQDcontrol for years without any of these features :-)

So while not exactly "important" the level metering can come in handy when you use matrix processing and/or ReplayGain ("Adaptive Gain") with levels above 0dbfs.

Great!

But take your time!

No, I certainly don't intend to. 😬

@Ales Prochazka please tell me, I would like to implement several functions in HQPE, I asked Miska, he says it can be implemented using the sources for HQP Control.
1. I would like to select one of the HQPE inputs and after the next start of HQPE, so that it remains on, and not the playlist which is always by default.
2. Make sure that when HQPE shuts down, the next time it starts, it automatically starts playing the track that was played before the shutdown. At least this is the case with tracks that are on local storage, and if possible, tracks on the network (of course, if they are visible on the network when HQPE starts)

Can you tell me in which direction to at least dig, I'm a C ++ teapot, I collect as much information as possible on the possibility of implementing these tasks.

Client applications connect to the HQP IP address, port 4321 (default). Communication takes place via TCP socket using XML messages.

 

E.g.:

Request: <?xml version="1.0" encoding="utf-8"?><GetInfo />
Response: <?xml version="1.0" encoding="utf-8"?><GetInfo engine="5.0.1" platform="Linux" product="Signalyst HQPlayer Embedded" version="5"/>

 

You might be interested in the following features:

• GetInputs
• GetTransport
• SetTransport
• GetState
• GetStatus
• ...

 

For example, you can use Wireshark to monitor the communication between HQPlayer Client and HQPlayer Embedded. Much can be deduced from this and from the C++ source files of "HQPlayer Control".

Thank you very much for the tips, it really opens your eyes.  It turns out that it will be enough to "feed" an xml file with the necessary settings over the network?

Is it possible to enable it without parameters? 
(the question is rhetorical as i tried but it doesn't seem possible … or is there some trick?)
