Hi DaneLLL,
Thank you for your reply.

I have read your talks, so I want to know except ximagesrc, how can I use your example to achived screenshot, have some API can I called.

Hi linwen,
The sample is to capture content with EGL APIs.

For screenshot, we don’t have specific API for it. Please other users can share experience.

Hi DaneLLL,

I am following the procedure given in GitHub - DaneLLL/simpleEGLStreams_producer in Tegra X2.

Internal data flow error occurs when I run the command nvgstcapture-1.0 --camsrc=3 --prev-res=3.

Error :

nvgstcapture-1.0 --camsrc=3 --prev-res=3
