I want to play my video from 2022-03-04 11:11:11 via open network bridge

​So, I tried Range: ntp 20000- and Range: clock=20220304T111111.000Z-

​

The First is working well and the second is not working.

​

This is second request . (I have to use that..)

​

Request :

​

I expected a video from 11:11:11, but the live video was played.

​

So, I found the latest rtsp log.

Hi Kim,

What I see on “prima-vista” is that (according to the RTSP spec) you need to change

Range: clock:20220304T111111.000Z-

to

Range: clock=20220304T111111.000Z-

Also please bear in mind that the provided timestamp is in UTC time (not a local one).

Thank you for your answer.

Then, How can I ​synchronize with the local time?

Hi Kim,

You need to convert your local time to the UTC (GMT).

For example if are in time zone UTC- 7, and you need to navigate to 11:11:11 (local time), you should send seek time as 18:11:11.

Opposite, if you are in UTC+7, you need to send 04:11:11.

Thank you!
