Hi,
I test 3d surround view use case in Processor-Vison 3.0. Please see the work flow for the use case at the last.
But eglCreateContext return fail. The following is the output.
[HOST] [HOST ] 62.464649 s: EGL: version 1.4
EGL: after eglCreateContext() eglError (0x3005)
[HOST] [HOST ] 62.815714 s: EGL: eglCreateContext() failed !!!
The following is the function which calls eglCreateContext. So is there a way to figure out the reason why eglCreateContext failed?
