    Default Timestamp (or other info about time) in IP-cameras data?

    hello!
    I think you know ...

    Are there timestamp (or other info about time) in IP-cameras data?

    I want to have overlay ( time with hundredth of a second) on my live video, but i can't use the Wowza transcoder feature, because it is very important to me to show exactly the time which the camera shows ( to the accuracy of hundredth of a second) (NOT WOWZA SERVER TIME)

    And if this data contain timestamp, how i can use it in some java interfeses or modules?

    Thanks in advance
    Andrey.

    I think you should utilize ONVIF METADATA somehow to acquire what you want. But as i remember Wowza is not utilizing any metadata at all from rtsp stream. Note that not every camera support ONVIF Metadata.

    I am pretty sure that Wowza does not support this. It comes up occasionally as unsupported track that Wowza will filter out if present by setting Application.xml /MediaCaster Property rtspFilterUnknownTracks to "true"

    WARN server comment - Failed to find an appropriate depacketizer for this track (vnd.onvif.metadata)

    Hi,

    Did you find a way to get the camera timestamp and not the WASA Server timestamp ?

    Thank you
