I’m on a Surface Pro 3 running Windows 10. Trying to record an mp4 from a native H.264 stream.
The H.264 video sources are on the second “pin” and I suspect that’s the problem. But the first and second pins have the same name, so I don’t know how to specify them. I was able to record from the first “pin” by removing the “-vcodech264”. Here are commands: >>>>>ffmpeg -list_options true -f dshow -i video="Microsoft LifeCam Front" ffmpeg version N-86848-g03a9e6f Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.1.0 (GCC)
