OMX_UseBuffer error 0x80001018 ! (state : 1)

[fuzun]

I have been trying to use camera_process.cpp but I get OMX_UseBuffer error 0x80001018 error after executing AllocateOutputBuffer:

    // Allocate buffer that will be processed manually
    camera->AllocateOutputBuffer( 71 );

Verbose output:

Adding input port { 73, 1 }
Adding output port { 70, 8 }
Adding output port { 71, 8 }
Adding output port { 72, 4 }

Hello, it looks like I've made a mistake in this sample, AllocateOutputBuffer should be called after putting Camera in IdleState. This should be fixed in https://github.com/dridri/OpenMaxIL-cpp/commit/af954b0 Sorry about that

@dridri It worked! I will tell if anything else goes wrong. I'm closing it now.
