Hi Jabl,
I did it already last Saturday on your request.
(You can also copy the ffmpeg string from the first item of this thread.)

Hi all.
It looks my H265 hard or/and software problem is solved.
Now the base situation is correct i can play with other settings.
Thanks to all for helping me.
Thanks and 73,

I Robert some success
Can finally produce a ffmpeg signal on QO-100.
But I have to remove all patches from Roberto otherwise it won't work.
Anyway there is progress.

Robert, is that not a option for the H 265/264 black boxes as stated between the brackets?

Hi Robert,
I probably missed something,
Where can i find this option/switch "force compliance"
Thanks,

The encoder on my GTX1650 works that's a sure.
When i use OBS in the `recording mode` H265 works perfect.
It's only OBS in combination with FFMPEG gives me problems.

Thanks for the answer to my question.
I'll test your Bat-file and see if it works.
If it's an IP address or a firewall problem, why is the audio working properly?
(Just the video part is missing)
Hi all,
My plan is to put a H265 signal on the WB of QO-100.
I know there are small black-boxes, HDMI in and UTP out who can do the job.
But i have already all the hardware in my computer, so why not use it.
H264 is not the problem, can put a good picture on the satellite.
My system:
Hardware Intel I7 cpu with a GTX1650 video card, Adalm-Pluto
Software Windows-10, OBS studio, OBS-VirualCamera, FFMpeg and VLC
All software and drivers are updated to theire latest versions.
This is my bat file:
ffmpeg -f dshow -rtbufsize 1M -i video="OBS-Camera" -thread_queue_size 512 -f dshow -i audio="OBS-Audio"
-vcodec hevc_nvenc -r 10 -s 1280x720 -pix_fmt yuv420p -preset slow -rc cbr -rc-lookahead 5 -b:v 90k -acodec aac
-aac_coder twoloop -ar 48000 -ac 1 -b:a 24k -f mpegts -muxrate 160k -streamid 0:256 -streamid 1:257
-max_delay 3000000 -pcr_period 40 -pat_period 0.4 "udp://238.0.0.1:8282?pkt_size=1316"
With the GTX 1650 nvidia encoder it should be possible to make H265.
Can start a movie in OBS via VirtualCam so i can watch it in ffplay and VLC.
It is also possible to send it via my pluto to QO-100
Only in the following modes "-vcodec libx264, -vcodec libx265 and -vcodec H264_nvenc"
Audio en Video are all fine.
But now "-vcodec hevc_nvenc" can play it in ffplay, nice audio and video, but can't play it in VLC and send it to my pluto.
In VLC only the first 1 or 2 seconds there is video than the pictures freezes, but the audio continues (with good quality)
On my Pluto the same effect as with VLC.
Does someone a idea to solve this nasty problem.
After more than two weeks of testing and trying, now running out of options.
Thanks in advance,

No Raspi.
My TRX is the ICOM IC-9700
Modem is running on my PC
Hi all,
Installation of the High Speed Modem on my 64Bit Windows-10 computer, peace of cake.
The only problem till now is the USB-Audio connection
My IC-9700 is in USB-D mode (Rx and Tx)
I did a test with KG-STV that works fine, so the USB-Audio connection must be good.
( The IS0GRB wed-sdr did received a picture from me )
Playing around now a couple of hours with the audio part without success.
What do you guys have for info on the command screen (you can see my error).
Hallo,
Probably i missed something about this project.
Where can i find more info about the "high speed modem".
I presume it's a software solution or ........
A search on this forum did not help me.
I found the site from DJ0ABR. ( as you can see in the top of the images a call-sign).
But i would like to see if there are some users experience.

Hi all,
To expand the question from Trevor.
Is there maybe a list with (roughly) indications for the SNR what we can expect for a particular antenna size?

Bert
Thanks Roberto and Evariste for the fantasic job you guys are doing.
Maybe you can add also the Amsat-DL down-up transveter in the "Transverter OL" list, we are here on the Amsat forum.......

Is it not wise to ask PE1RKI, he makes those things.
