[FFmpeg-devel] [PATCH v7] - Added Turing codec interface for ffmpeg

Dear Mark,

We provide our custom Boost libraries. In our tests we are able to build and run using just "--enable-gpl --enable-libturing". We would prefer to keep the pkgconfig file. I am not sure I fully understand what is required to be changed there (if anything), could you please be a bit more specific?

Thanks a lot,

Also the pkgconfig file:
* It refers to the libturing build directory, which need not exist after installation.
* I think libstdc++ and the boost libraries are always required, not just when linking statically.  (Not sure how this interacts with other parts, though - it seems to not like the system boost libraries on Ubuntu 16.04 (1.58): do you need to install your custom boost libraries as well?)

It should be possible to build and run with just "--enable-gpl --enable-libturing" on a clean "make install"ed libturing.
