Transmit Audio on H264

Post by G4APV » Fri Jun 26, 2020 10:35 am

Please forgive me if this has been answered elsewhere, if it has just point me in the right direction!

As Portsdown currently stands, can it standalone transmit H264 audio? I can make MPEG work, and using OBS can get H264 audio but I would like to build a standalone system. I've got an Easycap dongle, a sound dongle and a C920, none of them work as far as I can tell.

Apart from that I have a working system based on Minitiouner, Portsdown, Spectrian PA and a 1.3m offset fed dish and I am really pleased with how well it all works.

Thanks in advance

All Portsdown Buster 2020 versions can transmit audio with H264, either from a USB mic dongle, EasyCap or the C920. It's not the best audio in the world, but it works.

The older Stretch software should work OK with a USB Mic Dongle or an EasyCap, but did not work well with the C920.

Bob,
I have transmitted the active testcard with H264 across the bench with audio captured via EasyCap from an old Sony camcorder and it worked fine.

Thanks for your comments, it was operator error, something erratic but now seems to be behaving itself! Bob
