Gstreamer, используя ReSpeaker 4 микрофонный массив в macOS?

0 голосов
/ 06 июля 2019

У меня есть микрофонный массив ReSpeaker 4, который я пытаюсь использовать для своих пользовательских приложений. Однако, похоже, что gstreamer не обнаруживает устройство как Src. Хотя он обнаруживает выходной динамик устройства. Кто-нибудь может знать, как использовать usb mic на gstreamer в macOS Mojave?
