Replay from DVR

[DamianIngremio]

Hi, is it possible to watch replay from Hikvision DVR with rtsp-relay?
Watching live works well, but when im trying to send replay i got no response.

        loadPlayer({
            url: 'ws://localhost:port/api/stream?url=rtsp://usr:pswd@ip/Streaming/tracks/201?&starttime=...&endtime=...',
            canvas: document.getElementById('canvas'),
            verbose: true,
            additionalFlags: ['-q', '1'],
        });

From hikvision doc.
Live View URL
rtsp://

:/Streaming/Channels/

Playback URL
rtsp://

:/Streaming/tracks/

When copy-paste to VLC everything is working with live and replay, same url of replay on page doesnt.
