> Steps to reproduce the bug:
obs streaming: rtmp://172.24.0.75:1935/live/livestream

vlc streaming:
http://172.24.0.75:9080/live/livestream.m3u8

Streaming can be successfully pulled and viewed normally.

Get streaming client information, then kick the stream using API
DELETE http://172.24.0.75:1985/api/v1/clients/o7zw2527

Returns "code": 400

However, for the same streaming,
if VLC pulls the stream using rmtp://172.24.0.75:1935/live/livestream, it can successfully kick the stream using the API.
If VLC pulls the stream using http://172.24.0.75:9080/live/livestream.flv, it can also successfully kick the stream using the API.

May I ask if SRS does not support HLS API stream kicking, or is there another reason?

Expected behavior (Expect)

Expected API behavior:

Expect the API to support HLS stream kicking.

Is it because HLS is connectionless, only downloading index files, so there is no concept of streaming, therefore unable to eliminate?

Has the original poster resolved it? I have also encountered the same issue. HLS is essentially file downloading. It seems that the /api/v1/clients and /api/v1/streams interfaces do not include HLS statistics. I want to know how to selectively kick out video streams in HLS.

If HLS is distributed through NGINX, it requires support for stream eviction on NGINX.

If using SRS distribution, SRS 5 already supports streaming HLS, so it is possible to achieve this capability.

This capability can be considered in SRS 6.
