stream error: raspberry cam no work #8

Closed corsariovasco closed 2 years ago

corsariovasco commented 6 years ago

Hello,

I playing with python and opencv, in concrete with pipcamera, but i see yours work and as I love R...i will test it...the installation into raspberry works me...R...libraries: ROpenCVLite and Rvision... ROpenCVLite::opencvVersion() "### Version: 3.4.1" It is fine. In the case of my first test... an image capture: my_stream <- Rvision::stream(0) "### Error in new_CppObject_xp(fields$.module, fields$.pointer, ...) : Could not open the stream." This is not worked me.

I have used a raspberry cam and this working on pipcam and raspistill. In your library, have you any limited on cams?.

Kind regards,

@corsariovasco I do not have the possibility to test the package on Raspberry Pi (I can only test it on Windows 10, Ubuntu-family Linux, and Mac OS X). Therefore I can't really help with this problem at the moment.

@sjmgarnier :-( Thanks... what is your technological stack (IDE: atom, vs, R studio?. Might you tell me how to debug? ... Maybe I could collaborate. I could install R studio into raspberry and execute your source. That's enough!, i do not know it.

A question... what is the origin the list of all supported APIs based on StreamClass?...the opencv has more but i do not found the definitions. Maybe the raspberry has its API own.

Kind regards,

@corsariovasco I develop using RStudio.

Supported APIs should be detected by cmake when compiling OpenCV. It's possible some option must be activated when compiling on Raspberry. I won't have the time to investigate this myself before a while. Let me know if you find anything.

Thanks for your reply.
