Converting opencv image to ffmpeg

opencv-ffmpeg's Issues

Command to compile

Hi,

I appreciate your code and it's quite helpful for me to understand it.

Could you share the command to compile with g++?

I tried with g++ writevideo.cpp -lavcodec -lavformat -lavutil -lswscale -lm pkg-config --cflags --libs opencv -o writevideo

But I'm getting error as 'undefined reference to symbol 'pthread_join@@GLIBC_2.4''
So I added -lpthread after which I got the error as 'undefined reference to symbol 'avpriv_solve_lls@@LIBAVUTIL_55'' even through -lavutil library is included while compiling.

It would be great if you could assist me in this.

Thank you.

Adapt your code to ffmpeg 4

Hello,

First over all, thank you very much for sharing your code, much appreciated !!

FYI I tried to build it, and after some modifications, I was able to make it work using ffmpeg 4.x and OpenCV 3.4.0 (should be forward compatibile without too much of problems)

Everything is now at : https://framagit.org/ericb/direct_cv_encode (apologies, I no longer use github repo)

Last but not least, I'll attach the full code diff (.txt since github does not accept .diff ...). Everything is under MIT License, so feel free to use it ... or not :-)

Thanks again !
