I downloaded the software recommended on the Jetson site. It's a customised version. I wonder if you did this?
Yes Mike the download comes from the link in your message.
I tryed with success another version of ffmpeg, but unfortunately works in a very bad way at lower speed.
Now I'm starting from a fresh installation and following exactly the description done in the BATC forum for the Jetson nano DVBSDR.
The result back to no TS in the tx. There's something of wrong in the ffmpeg, because I Checked the UDP stream on NANO, with tcpdump. Packets coming regularly, same test made from Robert.
I will need a Teamviewer session with Evariste, but my opinion is that this is a "abandoned project". He starts to develop new solution for Pluto, may be he haven't interest to continue on Nano project.
