Я добился успеха на macos и linux с:
Linux:
ffmpeg \
-f v4l2 \
-framerate 25 -video_size 640x480 -i /dev/video0 \
-f mpegts \
-codec:v mpeg1video -s 640x480 -b:v 1000k -bf 0 \
http://localhost:8081/supersecret
Тест MacOS:
ffmpeg -f avfoundation -framerate 30 -video_size 640x480 \
-i "0" -f mpegts -codec:v mpeg2video -s 640x480 -b:v 1000k \
-bf 0 http://localhost:8081/supersecret
Я уже установил ffmpeg на windows просто нужна правильная команда.
Мой журнал ошибок:
/dev/video0: No such file or directory
Обновление:
После ffmpeg -list_devices true -f dshow -i dummy я получил:
...
[dshow @ 000001985949ce80] DirectShow video devices (some may be both video and audio devices)
[dshow @ 000001985949ce80] "USB Camera"

...
Затем я пытаюсь запустить свой сервер с:
ffmpeg -f dshow -i video="USB Camera" -framerate 30 -video_size 640x480 -f mpegts -codec:v mpeg2video -s 640x480 -b:v 1000k -bf 0 http://localhost:8081/supersecret
И я ловлю этот журнал :
