问题 I was just wondering if there is any feature like RTMP in Kurento Media Server . I need it to stream my vod content . Any ideas ? anyhow RTP can be used for it ? Thanks Pawan 回答1: There isn't a rtmp endpoint in Kurento, at least yet. But we have streamed content to a Wowza mediaserver using an RTP Endpoint with the last kurento development version. Maybe this can also work for you. 来源： https://stackoverflow.com/questions/27203318/how-to-do-rtmp-streaming-in-kurento-media-server

问题 I'm trying to implement a video streaming solution based on user access.
