Скрипт RecordRTC позволяет осуществлять запись с веб-камеры через веб-страницу.
Один из их скриптов предназначен только для ручной записи, другой — для автоматической записи и загрузки.
Оба скрипта успешно работают по отдельности.

Я надеюсь, что кто-нибудь сможет просмотреть это и предложить, как достичь моей цели: запустить, остановить и затем загрузить.
Большое спасибо за любую помощь.
