Your setup is easy, quick and worked at first, as I said I had to go until 275Ks for stability, at 768x576 ou even 480p the image quality from the conversion of h.264 (from OBS) to h.265 it's OK, but I expected better with my C920, still very stable setup !!!
BTW, what is your delay on QO-100? I have about 3 or 4 secs max ...
Now with dvbsdr I have better quality with the same hardware and as I described on my last post, a delay of 4 secs, I wasn't successful with the lime FGA firmware, which can give me better quality, because when in use the delay is too much +- 9 secs, so I may have to tweak with some parameters?
For the moment I can't say the dvbsdr is very stable as your method, I'm doing more local tests, I do want an easy system and stable and the ability to work also with OBS ...
If it fails, I will prefer to use your setup instead of the dvbsdr ...
Again the use of jetson nano is cheaper than a new computer and it can interact with porstdown for h.265 encode without the use of PC, I tried to use
the picam V2 and the quality is acceptable, I can compare to my C920 using your setup, I just have to figure out how to add my call on screen, as we
have on porstdown mpeg2 ...
I still have a lot to learn but I think to have now everything to go on air and try some contacts, maybe we can have a QSO by sat

My Lenovo Mini-PC is supposed to be the home of the video for streaming and OBS in this arrangement. It fails to display video from YouTube and crashes to the blue screen. VLC media player open video command is the same. I'm not too hopeful about it streaming a film with OBS on the local Portsdown LAN without crashing. Audio, regular programs and Minitouine are fine. It's a bit of an Achilles Heal!
Do you know if the Linux version of OBS would run on the Jetson Nano and would streaming to IPTSIN on Portsdown still be possible without a PC?
I've a perfectly good screen on my rack (as you know from mending it) which could use its HDMI input from the Nano. Another keyboard and mouse would be tolerable.
Now I've installed LAN cables to my workshop and streamed to my M0YDH channel on the BATC streamer, I can resume my Jetson Nano to Portsdown streaming experiments - if the PC plays ball.
All the best and stay safe John

I tried OBS in Jetson board and it works (H264), you must apply a patch to an old version, but it's limited, you can read more, the reason, in this links:

Yes I found independently that Jetson Nano and OBS Studio are incompatible.
However I have updated a Dell Latitude D630 laptop from Linux Mint 17.2 up to 19.3 Tricia XFCE via an overwrite with the Live DVD. This does permit OBS and FFMPEG and it was at zero cost to me . Now I have to follow the OBS for windows settings in CQ-TV 265 and any from this article. There are two experiments to try
1) CQ-TV 265 style - make some Bash scripts that do what the Windows batch file did for H264 transport stream straight to Portsdown.
2) carry out the OBS export to the Jetson Nano per this article in order to make H265 in a 3 computer chain.
Hopefully the 2008 vintage laptop will perform adequately
I am experimenting to see if the Portsdown, with or without Jetson Nano, can be successfully used with a DVB-S2X/DVB-GSE system.
The best answer I can think of to your question is that if I was trying to generate DVB-S2 I would start looking at the modifications required in the C and C++ code that generates the TS in the Jetson Nano. It can't be done simply by changing the encoder parameters.
However, that would not be the approach that I would take - I would start by getting one of the open source GNU Radio implementations of the protocol working first on a PC.
