• HTTPS: https://test.flashphoner.com:88888444/rest-api/rtsp/startup

Where:

• test.flashphoner.com - is the address of the WCS server
• 9091 8081 - is the standard REST / HTTP port of the WCS server

Known issues

1. A stream containing B-frames does not play or plays with artifacts (latencies, lags)

Symptoms:

• a stream sent by the IP camera via RTSP does not play or plays with latencies or lags
• warnings in the client log:

Stream capture authentication

WCS supports RTSP stream capture authentication by user name and password, user data should be set in stream URL, for example

rtsp://user:password@hostname/stream

If name or password contains any special characters, they should be escaped such as

09rtsp:32:31,238 WARN 4BitstreamNormalizer - RTMP-pool-10-thread-5 It is B-frame!

Solution: request lower resolution video from the camera to avoid using B-frames or transcode that stream.

Where

• user is user name
• p@ssword is password with character '@', it is escaped in URL.
