Background: I am working on a Python project where, given a set of input files (text/image/audio), it generates an executable game. The text files are there to describe the rules of the game.

Currently, the program reads and parses the files upon each startup, and builds a Python class that contains these rules, as well as links to image/audio files. This is fine for now, but I don't want the end executable to have to bundle these files and re-parse them each time it gets run.

My question: Is there a way to persist the instance of my class to disk, as it exists in memory? Kind of like a snapshot of the object. Since this is a Python project, my question is specific to Python. But, I'd be curious if this concept exists anywhere else. I've never heard of it.

My aim is not to serialize/de-serialize the class to a text file, but instead load the 1's and 0's that existed before into an instance of a class.

Why doesn't this exist?

Take dried beans, roast 'em, grind 'em, and brew some bean juice?

I have no idea if it would taste good or not, but we don't know if we don't try.

Edit: I need to see what dried beans I have and maybe go shopping. I will give this a try with a couple different types of beans and report back if I fart or not.

Can anyone help me figure out Frigate/go2rtc

I have two cameras in Frigate.

One is a Raspberry Pi 3 running Monocle server, and this stopped working in Frigate some time back (driveway). The second is a Galayou G7 (nursery). The nursery camera is the one I am concerned about with this post.

Problem: Up until a month or two ago (I must have ran an update but I don't know) the audio from the Galayou camera worked in Home Assistant. I'd like to get that working again. Some searching led me to try setting up go2rtc in my config.

Here is my config before making any changes:

mqtt:
  host: 192.168.1.10
cameras:
  nursery:
    ffmpeg:
      inputs:
        - path: rtsp://redacted:[email protected]:554/live/ch1
          roles:
            - detect
    detect:
      width: 1280
      height: 720
  driveway:
    ffmpeg:
      inputs:
        - path: rtsp://192.168.1.240:554/recording/7824851880350319106/replay?trackid=8836591
          roles:
            - detect
    detect:
      width: 1920
      height: 1080

This currently provides only jsmpeg video in Frigate. If I add something like this to the end:

go2rtc:
  streams:
    nursery:
      - rtsp://redacted:[email protected]:554/live/ch1

this adds mse and webrtc as options in Frigate. But, mse plays only video, no audio. And webrtc loads neither audio nor video. I have tried adding lines like - "ffmpeg:nursery#video=h264#audio=aac" and also with opus but to no avail.

Finally, if I ffplay rtsp://redacted:[email protected]:554/live/ch1 it loads audio/video without a problem. I'm also able to connect via ONVIF at onvif://192.168.1.241:8899 from onvif-gui.

So, something is wrong in my Frigate config, and I don't know what. I'm hoping someone here is a little more familiar and can give me a pointer or two here?

Update: Here is the fix, in case anyone comes across this later:

go2rtc:
  streams:
    nursery:
      - "ffmpeg:rtsp://[email protected]:554/live/ch1#video=copy#audio=copy#audio=opus"
  webrtc:
    candidates:
      - <server-ip>:8555

The webrtc section got webrtc to work in the Frigate and video back in HASS. The #audio=copy#audio=opus got audio working in webrtc.

This is probably a stupid question, since 2 > 1, but here goes...

I have a home server. It's a ComputerLINK 1U rack server I bought off eBay some years back. It has 2 CPUs, Intel Xeon E5645 2.4Ghz(https://ark.intel.com/content/www/us/en/ark/products/48768/intel-xeon-processor-e5645-12m-cache-2-40-ghz-5-86-gt-s-intel-qpi.html). It also has two 750W power supplies, but I have one unplugged. It also has RAM and 5 HDDs.

I also have the guts of my old desktop PC. The CPU is an AMD FX8350 4Ghz(https://www.amd.com/en/products/cpu/fx-8350). The motherboard is some ASUS model, I forget and don't want to check right now. A potential PSU would be 500-600W range.

My question: I am considering moving to use my old PC parts as a new home server. One benefit is to cut down on the noise (rack mount PC fans are LOUD). But the real gain I would want is on power savings. So, if RAM and the multiple HDDs all stay the same, but I moved them to the AMD/ASUS CPU/motherboard, can anyone definitively say this will be more power-efficient?

I am not very knowledgeable when it comes to electrics or power consumption, and am just looking for someone to confirm for me. I am aware that the AMD CPU still isn't an excellent choice for an always-on machine, but it could be an improvement.

I have about this much left again still to pick too :)
