Can you try to use the base64 encoded username and password in the following format?
http://192.168.178.30/Streaming/channels/102/httppreview?auth=XXXXXX
You can get the “XXXXXX” part by going to https://www.base64encode.org and encode your username and password like the example below, and use the encoded value to replace the “XXXXXX” from the url above.
