i'd like to note that my camera lib version is 2.20,
i searched a lot but i did not find the error of( Sub astreams_newdata was not found.) in the forum,
i hope to solve that ,
thank you in advance.

There are several CCTV example. Which one are you testing? Have you made any changes?

The latest example is based on MJPEG: https://www.b4x.com/android/forum/threads/mjpeg-cctv-server.73792/#content
