Saya sudah mencoba semuanya
apt-cache search webcam |sort -u
dan semuanya memiliki beberapa masalah. Memperbaiki kesalahan sintaks, menunjukkan bagaimana menggunakan "GUI saja" dari CLI atau ffmpeg / mencoder / vlc one-liner yang bagus akan menjawab pertanyaan saya. Atau karena saya tahu cara membuat ffmpeg mengambil MJPEG singkat, menunjukkan cara melepas jpeg pertama akan berhasil, saya kira. Tetap saja, ini seharusnya lebih mudah dari itu.
