Provides a web interface to generate ffmpeg commands (works on every platform).
Out of interest: What does VideoToolbox do in that context? I found nothing in the readme that would require anything else than just ffmpeg. Or is it just the compiling of a custom ffmpeg build that is VT specific?
VideoToolbox is the encoder that FFmpeg links to.
So when vt-enc only creates ffmpeg commands why is VT a dependency for the whole prpject?
vt-enc calls FFmpeg which calls the VideoToolbox encoding framework. Without VT, ffmpeg commands will fail
But ffmpeg works fine on other platforms without VideoToolbox. So why do I need VT for vt-enc? Wouldn't it work just fine on other platforms as long as ffmpeg is available?
You need VideoToolbox for this particular tool because it calls the VideoToolbox library from within FFmpeg in order to encode the video.
"Why do I need x264 to encode H.264 in FFmpeg?" is essentially what you're asking. FFmpeg needs VideoToolbox support to work with my tool.
If you're asking why I chose to use VideoToolbox in the first place, it was because I want this to be a macOS-specific tool with very fast encoding speeds at decent fidelity per bit. Hardware accelerated video encoding is one way to make this happen.
