Portsdown 4 Update with Touchscreen RX Volume Control

Post by G8GKQ » Mon Sep 06, 2021 7:47 pm

I have just released a Portsdown 4 update (Version 202109051) which introduces a touchscreen-driven volume control for the DATV receiver. Simply touch the far right of the screen, above centre for volume up, and below centre for volume down. Details here: https://wiki.batc.org.uk/DVB-S/S2_Recep ... me_Control

The idea is those who have built Langstone designs with the soft or rotary volume control can use their equipment for DATV reception without needing a hardware volume control. Volume settings are persistent between reboots.

Note this control only currently works for VLC (not OMXPlayer) when receiving DVB-S/S2 or DVB-T. The other media players will gain the facility as I migrate them away from OMXPlayer (which is no longer supported by its original author) to VLC in future updates.

Please report any bugs here.

Handy for my bare-bones PD4/LS, I don't need to take a mouse with me now.
Tested on DVBS2 and DVB-T.
Could the 'Volume %' text be moved down to perhaps screen central and persist for twice as long as present? No rush ;-)

Thanks

Gareth
