QO100 ports down Transport Stream file TS

Post by iz4ryb » Sun Nov 03, 2019 9:42 am

Hi,

I'm using Portsdown with QO100 and lime sdr mini it works perfectly.

No problem with pi cam at 1ms, no problem streaming with Vmix at 1ms.

I'm currently using 1.2m dish with dual patch and 120w pa.

I did some trial with portsdown TS file, I create the avi file with vmix, I than convert
the avi to ts using VLC convert.

Minitioune shows mer 4,8 and D2 as usual, it shows all green light but no audio and
video.

Has anyone done some experience with portsdown ts file?

Bye!

Hi

TS Input to the Portsdown/Lime combination was not tested before release (there is only so much testing that I can do), so I would not be surprised if there are some problems. I do know that it only works at some SR/FEC combinations.

Hi,

many thanks for your answer.

I'll expected it was an Sr/fec problem. I did a first trial generating an avi file from Vmix with 8Msymbol.
Then I've converted the avi to ts using VLC convert. Testing this ts file with portsdown it worked losing sync
every 10 second but I was able to see images and audio from minitioune. I then thought I had to generate
the avi file not with 8Msymbol but 1Msymbol as my ports down current setting. Converted again to ts, transferred
to portsdown no way to see and ear anything from Minitoune.

Is the ts SR and Fec hard coded in portsdown or is there any configuration file to change.

I'm willing to use portsdown with pi camera for video Qso and ts for video tests because it is faster
than running vmix from pc, running the streaming bat and connecting everything via specific router.

Thank you in advance.

Bye!
