VNCtalk Resources & Requirements

VNCtalk System Requirements for Clients

VNCtalk Webclient (Linux/MachOSX/ Win64)

The Hardware of your installed operating system must be capable to execute the Google Chrome/Chromium web-browser properly. If you can use YouTube, then your are ready for the VNCtalk Webclient as well. Current versions of Google-Chrome/Chromium, Firefox-ESR and Firefox Quantum are supported.

Mobile App

  • iOS:
    You can find an overview on VNCtalk compatibility in regards to iOS devices here.

  • Android 9 and newer

For both mobile operating systems, you need to at least fulfil these hardware requirements:

  • CPU: 2 Cores (1,8 GHz per Core)
  • Memory: 2GB RAM
  • Internal Storage: 1GB min free internal space.

Required Network-Bandwidth for video calls/conferencing

While for your upstream bandwidth 1MBit/s is the minimal requirement in order to use VNCtalk video conferencing properly, depending on the number of participants, you need to provide at least this amount of free downstream bandwidth in order to run VNCtalk properly on your Client:

Number of participants Required minimal bandwidth in Mbit/s (down)
2 1.8
3 2.6
5 3.4
n 0.8(n-q)+1

This means, per AV-Stream at least 800kbit/s are required for proper functionality, if more is available, the quality of the stream is increased in resolution and bitrate depending on the participant's bandwidth abilities.

Required Network-Bandwidth for audio only calls/conferencing

While for your upstream bandwidth 256kBit/s is the minimal requirement in order to use VNCtalk audio conferencing properly, depending on the number of participants, you need to provide at least this amount of free downstream bandwidth in order to run VNCtalk properly on your Client:

Number of participants Required minimal bandwidth in kbit/s (down)
2 256
3 320
5 448
n 64(n-1)+192

This means, per Audio-Stream at least 64kbit/s are required for proper functionality, if more is available, the quality of the stream is increased in resolution and bitrate depending on the participant's bandwidth abilities.

Required minimum Network-Bandwidth without A/V conferencing

To use the VNCtalk web client and mobile app features, except A/V-conferencing (Chat, etc.) you need at least GPRS/EDGE/ISDN connectivity in order to have fun with it.
