MMM-AssistantMk2 problems when using electron-rebuild

Currently, I’m not in front of my device, so I write this without test.

 npm install [package]@[version]

That is a usual form.

Thus,

cd ~/MagicMirror/modules/MMM-AssistantMk2
rm -rf ./node_modules/grpc
npm install grpc@1.13

would work, I think.

if anybody needs a working raspie3b+ image with hotword/notification/assistant installed drop a pm

:-)

@Sean
works like a charm, thank you

@Sean

off topic: is there a way to set the audio output (Device / Program) routing like “record” for the mic?

I didn’t make it configurable much. But you can modify ‘node_helper.js’ by yourself

var speaker = new Speaker({
channels: 1,
sampleRate: cfgInstance.conversation.audio.sampleRateOut,
});

You can add here ‘device:”hw:1,0”,”. I’ll fix them to be configurable next update.

cool, works, thank you so much. Would you know where youtube audio is configured? Because that still uses the standard.

@yep_dd I don’t know about that, sorry. :| I think you should adjust your mixer (alsa? or pulse?)

[yep_DD]

@Sean
correct, works. Modified /usr/share/alsa/alsa.conf for the default sound card and added a “record” for MMM-Hotkey so it wouldn’t use that as default: working just fine.

Just stuttering, the audio output as well as video. Let’s see why… when audio is played through the 3.5mm jack it works fine.

@Sean

what is your CPU usage when playing youtube videos and using the google assistent? I am using OpenGL for rendering… but videos and audio via HDMiIseems to stutter

[dvbit]

@yep_dd I am using rpi3b+ sound output via HDMI.no stutter.

@dvbit Frankly I use mainly Asus Tinker Board. I couldn’t satisfied with performance of RPI3,
anyway, usually, with BT speaker, RPI3 has good enough sound. For video, I think non-HD youtube video can be played enough.

[dvbit]

@sean yes I saw your posts and realized it. Also had a look and thought about getting an asus but finally went for raspb3 for gpio support (at least in my readings it was saying it was suboptimal…)
I might give an AEON with atom (that I have) a ride if more power is needed.

PS: I went through the google sdk to understand current capabilities (especially in my language) and saw the output limitations you mentionned.
I could not find a list of supported features compared to smartphone assitant. do you have any pointer? tx

@dvbit For screenOutput? At this moment, Nothing. It is experimental stage. Screenoutput is too tight binded with specific hw. By example, original search results of video is not playable. It is assumed to activate app on smartTv. I had to parse static html output to catch youtube Video Id.

[yep_DD]

I switched back to headphone jack output and it is the same. Video and sound stutters.

@Sean

Tinker Board looks promising… will take me a while to set up and I am working the next couple of days, let’s see :).

[yep_DD]

@Sean I’ve just tried the google voice hat with your module, it works fine and a lot smoothe for some reason. I disabled the BCM soundcard and no stuttering except of the first google assistent replies right after boot up. Still on RPI3, let’s see with tinker board.

[yep_DD]

one more thing, I noticed when using the newsfeed module it stutters when fading to the next headline, can anyone confirm that? Performance is 10000x better with TinkerBoard than with PI3

[yep_DD]

If anyone is interested, no matter what Board you use the performance is dramatically reduced as soon as you rotate the screen. This is a measurement of PI3:

• I executed glxgears without vsync.
• measurements are average of fps

So without rotation the performance on the pi3 is a lot better. On the Tinkerboard it is even worse as it only supports Open GL ES and I have not found a solution to get that running with Electron.
