Minitioune audio stops after 4 sec when RXing DatvExpress

Messagede gw8bvi » Dim 12 Nov 2017 12:13

Why does Minitioune audio stop after 4 seconds, when receiving from a DatvExpress? Video continues.
- v0.6 and v0.7b doing the same.
- Win 10 (2 machines) and Win 7 Pro doing the same.
- LAV Audio Decoder, Splitter 0.70.2
- I tried increasing the Queue memory size and Queue packets in LAVfilter splitter, but still doing the same.
Minitioune audio OK when receiving from local repeater (it uses DTX1 as modulator). Audio keeps running.

Thank you

the DATV express transmitter software doesn't work well and most of time is not able to send a good TS with the good timing, so as Minitioune use the Windows demultiplexer that needs a normal TS with good clock, the result is frozen pictures or audio stop.

only a basic set top box that doesn't take care of timing, audio and video synchronization, can show video and sound.
As Minitioune, all professional DVB receivers will refuse to work with the DATVexpress signal.

Thank you Jean-Pierre for your reply. I find V2 Minitiouner + Minitioune very useful; 333kS/s 146.5 MHz (N.o.V.) QSO have been made possible where wider bandwidth signals could not possibly make the journey. Perhaps a future version of Minitioune could include a mode to tolerate poor TS timing accuracy. What you have achieved so far is marvelous!

Hello Phil,

Evariste F5OEO is working on the DATV express software. We have spent the 4 last days with test. Now the UDP mode is added to the DATVexpress transmitter. that allows now to use this card for low SR and DVB-S2.
In the future I think that the making of TS will be good.
