x86 Systeme (PC) / [MLD-5.5 testing] Bluetooth Audio + Sony LDAC, aptX, aptX HD, AAC codecs

« on: August 01, 2022, 20:09:03 »

Hi,

I was interested to use my MLD system as a bluetooth speaker for my phone or transmit audio from my MLD system to bluetooth devices.
I have succeeded in doing that by installing Blueman, it also has other features like using your phone as a bluetooth modem for your pc, creating bluetooth networks, sending/receiving files ... etc

Then while searching on Github i found the following repo

https://github.com/EHfive/pulseaudio-modules-bt

It allows you to add  LDAC, aptX, aptX HD, AAC codecs support to pulseaudio bluetooth modules.
I compiled/installed it and it works great 

I have added screenshots to show the difference before/after installing it.

Best Regards.

Hi,
I always wanted to have a way to display date/time, CPU temp, volume control when using MLD.

I found that nice application called Polybar, i compiled, installed it and it works great.
The only drawback it will displayed on top of other applications if you click on the maximize button of that application however it will be hidden in fullscreen mode.

Hi,
I found that application on Github however my question is not related to the application itself 
I just want to know how i make it look as the above screenshot because it look like this under MLD




Is that possible?
Which theme should i install?
I have read on google that you can install Linux Mint themes on Debian, right?

x86 Systeme (PC) / (MLD-5.5 testing) OpenWrt

« on: May 22, 2022, 21:54:24 »

Hello,

I was successfully able to run OpenWrt under MLD-5.5 Testing using Virtualbox 
However they don't provide dvb packages.
You have to build it yourself in OpenWrt SDK.
Is there anyone here uses OpenWrt who build dvb packages?

Best Regards.

Allgemein [ General ] / [MLD-5.5 testing] vidtv

« on: March 01, 2022, 16:35:46 »

Hi,

I build vidtv (Virtual Digital TV driver) while building new kernel for MLD,
However, i don't know if it can be used as vtuner or it has other purposes.

It consists of:
- A fake tuner driver
- A fake demod driver
- A fake bridge driver

vb_vidtv_tuner.ko
dvb_vidtv_demod.ko
dvb_vidtv_bridge.ko

You can load the driver by running

Code: [Select]

modprobe vidtv
A new adapter will be registered as follow

Code: [Select]

dvbdev: DVB: registering new adapter (dvb_vidtv_bridge)
i2c i2c-22: DVB: registering adapter 0 frontend 0 (Dummy demod for DVB-T/T2/C/S/S2)...
dvbdev: dvb_create_media_entity: media entity 'Dummy demod for DVB-T/T2/C/S/S2' registered.
dvbdev: dvb_create_media_entity: media entity 'dvb-demux' registered.
vidtv vidtv.0: Successfully initialized vidtv!
I couldn't use satip-client because it works with vtuner module only.

You guys can test it and see how it works.

Best Regards.

Raspberry PI / [RPI4] Debian 11

« on: January 03, 2022, 19:45:38 »

Hi,

- Is there a plan to upgrade to MLD based on Debian 11 soon?

- I build kernel 5.15.11 which works fine on Raspbian Bullseye as in screenshot however i get kernel panic on MLD system.

I just want to know what are the changes which i should make to convert a config file from git branch to MLD config in order to avoid the kernel panic problem

Best Regards.

Raspberry PI / [MLD-5.5 testing] RPI4 softhddevice-drm HEVC hardware accelerated video decoding

« on: December 05, 2021, 06:51:33 »

Hi,

softhddevice-drm HEVC hardware accelerated video decoding on RPI4 can be easily enabled by using rpivid-hevc driver as you can see in screenshot.

I dunno why there isn't much info about that driver but it works 

If you want to test it, you can either build it yourself or wait for Claus to build/add it in rpi package 

Code: [Select]

MLD> modinfo rpivid_hevc

Hi,

There's a problem in Rpi4 docker package,
in order to fix it i replaced the following files from cgroupfs-mount debian package
cgroupfs-mount
cgroupfs-umount

The following files are missing as well
containerd-shim-runc-v1
containerd-shim-runc-v2

I got them from containerd debian package

Raspberry PI / [MLD-5.5 testing] Raspberry Pi 4 CPU temperature script

« on: November 11, 2021, 23:34:54 »

Hi,

Here is a script that monitors Rpi CPU temperature.
The script isn't mine
I made a google search and found it yesterday.
You can change time.sleep to whatever value you want.
(python 3 is required)

Code: [Select]

#!/usr/bin/python3
import os
import time

def temperature_of_raspberry_pi():
    cpu_temp = os.popen("vcgencmd measure_temp").readline()
    return cpu_temp.replace("temp=", "")

while True:
    print(temperature_of_raspberry_pi())
    time.sleep(1)
Best Regards.
