Сервер GStreamer RTSP с ошибкой TLS

Question

Я пытаюсь использовать GStreamer 1.7.1 для запуска RTSP-сервера с поддержкой аутентификации и TLS. Код, который я использую, почти идентичен file from source, за исключением #define WITH_AUTH и #define WITH_TLS.

Я запускаю сервер, используя ./test-video после компиляции, находясь внутри каталога примеров.

Чтобы получить доступ к течению, я соединяюсь с той же машины, используя следующую строку в терминале: gst-launch-1.0 rtspsrc location=rtsps://127.0.0.1:8554/test user-id=user user-pw=password tls-validation-flags=generic-error ! rtph264depay ! avdec_h264 ! videoconvert ! osxvideosink

После того, как я пытаюсь запустить клиент, сервер выдает эти сообщения:

Я в настоящее время пытаюсь использовать машину OS X El Capitan, но у меня также есть попробовал в ящике Linux Mint 17.3 и получил одинаковые сообщения.

Есть ли у кого-нибудь идеи о том, как я могу решить эту проблему? Спасибо за любую помощь заранее.

Answer 1

Эти ошибки, вероятно, связаны с тем, что gstreamer или glib не могут динамически загружать модули.

Первая регистрация:

С любым из функциональности TLS, Glib динамически загружает в модуль TLS. По defualt это модуль gnutls. На Ubuntu это можно найти в /usr/lib/x86_64-linux-gnu/gio/modules/libgiognutls.so. Эта зависимость обеспечивается glib-networking (https://github.com/GNOME/glib-networking), если вы хотите скомпилировать ее самостоятельно.

Второй Проверил:

После рукопожатия TLS завершена, сервер RTSP затем переходит к настройке канала SRTP. Если плагины SRTP не существуют в системе, программа выведет CRITICAL ошибки. Запустите gst-inspect-1.0 srtpenc и gst-inspect-1.0 srtpdec, чтобы убедиться, что эти плагины существуют и что их зависимости выполнены.
