QuietPixel created ticket #30
Memory leak in private_types.h membuf class

I needed the ability to change the brightness and contrast on the fly, but setting the parameters without releasing the camera gave different results than when I would restart my program and use the same settings with a fresh instance of RaspiCam_Still. So, today I looked into implementing the release() function. I have a version which works, and would like to propose adding it to the next version of raspicam. Proposed changes: raspicam_still.h -- remove comment "//not working" raspicam_still.cpp...

Another solution would be detecting the opencv version being used and decide to use the older CV_CAP_PROP_FRAME_WIDTH or the newer cv.CAP_PROP_FRAME_WIDTH from videoio.h

OldETC posted a comment on ticket #21
further research: refer to "libelf by Example", a pdf file talking about the format of ELF binary files. It appears that the ELF header has a string table i.e. strtab built in. So when the files are built by the make command, the string table is created (there are three tables in the file with strtab being the last.) Something is messing up the g++ compiler. When the loader access the file, it attempts to read the string tables to identify each library file''s content and locate the procedures. With...

I begain experiencing these errors just recently.

More information: if I follow the steps listed on this page: http://www.uco.es/investiga/grupos/ava/node/40 (identical to the sourceforge readme file I think). This is built using cmake (I have very little experience with cmake). The library builds along with executables for raspicam_cv_still_test, raspicam_cv_test, raspicam_still_test and raspicam_test. All of the executables created with the cmake scripts run correctly. However, if I follow the directions for "Using it in your projects", I am unable...

I have this problem too. Raspberry pi 3 model B. I'm guessing this is something simple? It seems to be preventing me from a successful build in the later steps.

This Picture ist overexposed. You should set the exposure mode to auto.

I have this problem as well. Raspberry pi 3 model B libraries built with version 0.1.6 and 0.1.4 fail to link when included in my project. The problem doesn't seem to happen in version 0.1.3

Hey i am having the same problem, in the attachement you can see it hangs at capture. I ran the default test app with no changes. right after a fresh start. Also a side note: make install does not copy the raspicam_still.h file (i manually copied it and everything builds fine)
