The compilation is completed smoothly but cannot run smoothly. I will copy the files under "examples slice" to a new project. And added "dependencies" (trusty_ffmpeg="0.13.1+ffmpeg. 6.0"), which encountered an error during the compilation process.

Is this situation already considered a successful compilation. The only remaining issue is video encoding!

Is this situation already considered a successful compilation. The only remaining issue is video encoding!

Yep, the complation succeed. You can change included codec by tweaking features in vcpkg FFmpeg, or build your own FFmpeg without vcpkg. That's a far more complex topic.

You can also check rsmpeg if you want safer method.

Feel free to open another issue if you encounter any other problem.
