Я пытаюсь сделать приложение для видеоконференций (написанное на C#), которое позволит 2 пользователям видеоконференции с использованием TCP. Кроме того, пользователи могут отправлять текстовый чат отдельно. Прямо сейчас у меня есть рабочий видеопоток, но пока нет звука. Я не знаю, как получить доступ к микрофону, передать его с помощью TCP, а затем воспроизвести его на динамиках других пользователей, поскольку я относительно новичок в C# и новичок в использовании носителей.Попытка потока 2-way аудио через TCP?
Если кто-нибудь может указать мне на образец кода, помочь мне узнать, как получить доступ к микрофону или что-то еще, что, по вашему мнению, мне поможет, это было бы здорово.
Я прикрепляю свой код как для справки.
