Я разработал сервер RTSP на основе ffserver, который транслирует живое видео, я могу транслировать и отображать видео на mpv и ffplayer.но на VLC-плеере я вижу только первое изображение, затем оно не показывает другие кадры.
Вот журналы вывода VLC -vvv:

Здесь вы видите, VLC всегда ждетпри буферизации, в то время как другие игроки могут получать буферы от моего сервера RTSP, также я вижу пакеты RTP на Wireshark, которые сервер постоянно отправляет данные в VLC.
Может ли кто-нибудь помочь мне в этом вопросе?
Большое спасибо заранее.
