Using namespace is not allowed in header file

[GrbavaCigla]

Hi, I am currently writing CMake configurations for this project, I noticed few very big mistakes.
First one is that you should never use using namespace ... in header files. Here is explanation for that: https://stackoverflow.com/questions/5849457/using-namespace-in-c-headers
Second you should add header guards, here is explanation how and why: https://www.learncpp.com/cpp-tutorial/header-guards/

Also when I remove "std.h" which only for windows, I get errors, I fixed a lot of them, but one is still there

Hi,

@GrbavaCigla:

You can add: the way exceptions are implemented could be discussed too :-)

FYI, I completed the build on Linux writing a dumb CMakefile.txt, and I start some tests very soon.

TODO : I still have to fix all ffmpeg warnings, because the used API is obsolete+remains to implement something more modern.

Stay tuned :-)

In fact, just a question : on my side, I simply modified your makefile adding a new path for include dirs:

target_include_directories(${PROJECT_NAME} PUBLIC ${PROJECT_SOURCE_DIR}/source/ffmpeg-cpp )

I think it's more less boring than add #include "ffmpeg-cpp/(lot of .h files)" no ?

My current configuration is:

• linux x86_64 (LnuxMint)
• gcc-7.5 / g++-7.5
• ffmpeg 4.2.2 (releases, built from sources)

ffmpeg -buildconf returns :
