You can, however the precompiled version of ffmpeg is missing a lot of dependencies that are necessary (or you may need them somewhere in future). Therefore I would suggest compiling everything from source. Last but not least, the precompiled versions distributed with Debian are a bit outdated.

Hi, first I want to say thank you for creating such an easy guide for compiling OpenCV with FFmpeg on the Raspberry Pi. I began following your instructions but I had an error when I got to the step
make -j $(nproc)
The error code that I received was this:
/home/pi/source/opencv-3.1.0/modules/videoio/src/cap_ffmpeg_impl.hpp: In member function ‘bool OutputMediaStream_FFMPEG::open(const char*, int, int, double)’: /home/pi/source/opencv-3.1.0/modules/videoio/src/cap_ffmpeg_impl.hpp:2207:41: warning: ignoring return value of ‘int avformat_write_header(AVFormatContext*, AVDictionary**)’, declared with attribute warn_unused_result [-Wunused-result] avformat_write_header(oc_, NULL); ^ modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:206: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o' failed make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1 CMakeFiles/Makefile2:2557: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/all' failed make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 Makefile:160: recipe for target 'all' failed make: *** [all] Error 2

I have a Raspberry Pi 3B+ running the latest version of Raspbian and everything is up to date. I am very confused about how to solve this issue and I would appreciate your help!
Thanks
