Note: GStreamer was installed from source and it's version is 1.10.4 . The installed path is /usr/local.

Please help me, thanks!

Hi @xuewenxu,

Do you have another version of GStreamer also located in "/usr/local"? It's possible that the SDK CMake command is picking up a different version of GStreamer located there that doesn't meet the minimum version requirements.

Thanks,
Sanjay

Hi @kylecombes,

Can you double check if your gstreamer installation is ok? If you are still having problems, please create a new issue.

Hi @celinval and @yoelrc88,

Thanks for responding to my message. I'll pass this info along to the other person I was working with on this, but I'm not sure if he's still trying to fix it. I'll create another issue if we're still having problems.
