<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> </head> <body> Ok I checked a bit more and it seems everything could be set up correctly but `NDIlib_initialize` just returns false. Did you just change the machine where you run the docker? People on forums talk about CPU incompatibility <a class="moz-txt-link-freetext" href="https://forums.newtek.com/threads/linux-ndi-sdk-examples-broken-on-amd-machine.164762/">https://forums.newtek.com/threads/linux-ndi-sdk-examples-broken-on-amd-machine.164762/</a> You could google more about issues around that call and try to find some documentation around that call from newtek. What checks exactly do they do. If you really need to solve this and it seems that NDI is proprietary software you could try to reverse that function in library (Ghidra) and debug it to see where it fails. <div class="moz-cite-prefix">On 9/6/21 12:53 AM, Marc wrote: </div> <blockquote type="cite" cite="mid:39e90a4d99bf4e649c6e9537ba543739@f1-outsourcing.eu"> <pre class="moz-quote-pre" wrap=""> Yes but the same docker image works on centos7 host, and the binaries from the sdk seem to work.
