RTMP_ReadPacket, failed to read RTMP packet header, what's the problem?

Question

Nginx

Hello! In VLC, the stream works successfully, but the http output does not want to work. I rummaged through everything for this error, but did not find a solution, so I am writing here. Help me please.

Answer 1

HLS transmits the stream not via the rtmp protocol, but via http, which, in general, is implied in the name: HLS = Http Live Streaming.
Therefore, therefore, you need to look not at the address rtmp://..., but at the address, in your case, most likely this (it may be different due to server settings):http://***/hls/test.m3u8
