Replay

How to replay bug?

OSB pushes stream to 192.168.1.121, push stream address rtmp://192.168.1.121:1935/live/livestream/1
VLC pulls stream from 192.168.1.121, pull stream address rtmp://192.168.1.121:1935/live/livestream/1, can play normally
VLC pulls stream from 192.168.1.131, pull stream address rtmp://192.168.1.121:1935/live/livestream/1, can play normally
VLC pulls stream from 192.168.1.122, pull stream address rtmp://192.168.1.122:1935/live/livestream/1, cannot play

Just tested again, the player provided by ossrs.net can stream normally, but VLC cannot.

TRANS_BY_GPT3

mawenwu1983 · 2020-11-19T08:48:15Z

Continue testing, even using the SRS live official Android app, it is still unable to properly stream the 122 flow.

TRANS_BY_GPT3

mawenwu1983 · 2020-11-19T08:59:32Z

Use the Android version of EasyRTMP, which has the same effect as VLC.

TRANS_BY_GPT3

mawenwu1983 · 2020-11-19T09:02:09Z

To summarize, no matter what streaming tool is used, as long as the stream is pulled directly from two source servers, there will always be one source server's stream that cannot be pulled.
However, the official website's player does not have this issue, as it can successfully pull the stream from either source server.

winlinvip · 2020-12-01T12:25:29Z

Do not play the stream directly from the source server cluster. Won't fix.

TRANS_BY_GPT3

winlinvip · 2021-08-28T23:42:35Z

The origin server cluster must not be accessed from a specific origin server, but rather from the edge to pull the stream. Please refer to the document for details, buddy.
