SichboPVR per Linux

SichboPVR è disponibile su alcune varianti Debian x64. Se la domanda è sufficiente, è possibile aggiungere ulteriori distribuzioni e architetture.

Queste sono build pre-rilascio, ma sei il benvenuto a calciare le gomme su di esse. I repository stabili sono impostati ma non esistono ancora build stabili: tieni d'occhio le versioni stabili in futuro. I binari di Linux sono costruiti con lo stesso codice di Windows, ma il mio livello di astrazione della piattaforma non è ancora alla parità delle funzionalità.

Limiti attuali:

• I telecomandi non sono ancora stati aggiunti.
• Non c'è il controllo dei supporti del sistema operativo o l'integrazione della barra delle applicazioni.
• Il bit streaming Dolby Digital non è ancora implementato.
• "Esegui ridotto a icona nella barra delle applicazioni all'avvio del sistema operativo" non ancora implementato.

Requisiti minimi di sistema:

Il cliente (sichbopvr4)
Una GPU che supporta OpenGL 3.3 e decodifica hardware VAAPI, 1 GB di memoria video, 1 GB di RAM.

Il server (servizio sichbopvr4)
Praticamente qualsiasi PC o istanza VPS/VM: utilizza pochissime risorse.

Mi scuso per il fatto che questa pagina è disponibile solo in inglese.

How to install.

1. Add the Sichbo Interactive public key.

   wget -qO- https://sichbopvr.com/releases/sichbointeractive.asc | gpg --dearmor > sichbointeractive.gpg
   sudo install -D -o root -g root -m 644 sichbointeractive.gpg /etc/apt/keyrings/sichbointeractive.gpg
   rm -f sichbointeractive.gpg
               

2. Add the SichboPVR apt repository.
    
    

   Ubuntu

   Mint, Elementary, et al — Mint is reportedly the most stable variant for running SichboPVR.

   Ubuntu 24.04 (Noble)

   sudo sh -c 'echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/sichbointeractive.gpg] https://sichbopvr.com/releases/ubuntu-24.04/test noble main" > /etc/apt/sources.list.d/sichbopvr-test.list'

   Ubuntu 22.04 (Jammy)

   sudo sh -c 'echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/sichbointeractive.gpg] https://sichbopvr.com/releases/ubuntu-22.04/test jammy main" > /etc/apt/sources.list.d/sichbopvr-test.list'

   Ubuntu 20.04 (Focal)

   sudo sh -c 'echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/sichbointeractive.gpg] https://sichbopvr.com/releases/ubuntu-20.04/test focal main" > /etc/apt/sources.list.d/sichbopvr-test.list'

   Debian

   (MX 23, et al)

   Debian 12 (Bookworm)

   sudo sh -c 'echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/sichbointeractive.gpg] https://sichbopvr.com/releases/debian-12/test bookworm main" > /etc/apt/sources.list.d/sichbopvr-test.list'

3. Do the usual...

   sudo apt update && sudo apt install sichbopvr

Graphical setup.

The experience is identical to Windows. SichboPVR will be added to your programs menu. Just run it and it'll start the background service and scan in channels. You can also configure it to install as a daemon under Setup > Local TV Server.

Command line setup.

For a server setup over SSH, run:

sichbopvr4-service -configure

By default SichboPVR is locked down to localhost and only works with a SichboPVR GUI running on the same machine. The interactive server "-configure" mode will let you easily change the network settings so that it accepts connections from the internet and also set an initial admin password (a user/password is always required for remote connections.) Once set, use a SichboPVR client on Windows or an X11 Linux machine to finish configuring the server.

General Linux nonsense...

Display drivers. They're generally horrible.

The SichboPVR UI can't function at all or will function unreliably in the following configurations:

• Nvidia Nouveau: Is hopelessly broken and will freeze when multiple OpenGL contexts are created (required by some features) and it will not VAAPI decode. You need to disable/blacklist the Nouveau nvidia driver.
• Nvidia Proprietary: Needs vdpau-va-driver installed, it won't actually work because of a missing vaQuerySurfaceAttributes implementation. Somebody has made fixed builds here. H265/HEVC is not generally supported.
• i965 MESA: Everything appears to work okay for some time and then the driver will inexplicably crash on i965_gpe_utils.c#L1730.
• Older graphics cards: Might render garbage because fragment shaders need recent OpenGL shader features.

Disable/blacklist the Nouveau nvidia driver.

$ sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo update-initramfs -u
$ sudo reboot

Tuner drivers.

Avermedia TD-310

$ sudo modprobe dvb-usb-af9035
$ cd /lib/firmware/
$ sudo wget https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-demod-si2168-02.fw https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-usb-it9303-01.fw https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-demod-si2168-b40-01.fw

Insert the tuner
$ dmesg

Should say "'AVerMedia TD310 DVB-T2' successfully initialized and connected"

More notes to come, probably...
