IP camera video stream in Linux

[ilyas_ahmed]

Hi Experts,

I just want to know what options WinCC OA 3.15 can provide to stream a video from an IP camera in Linux. (over RTSP)
I know there is a Video EWO , but can it be used in Linux as well ?

Secondly, As per my understanding Video EWO only stream video from the vimacc video server (this.showLive(Camera_00001@server1:9375, 1).
Is there any EWO which can stream video directly from the IP camera in Linux. (In Windows I guess we can use VLC ActiveX)

Appreciate your support and help as my knowledge is limited on this topic.

Thanks.

Ilyas.

Hi,
attached you can find all supported platforms:

According to your second question, there is no other EWO in Linux for a video stream.

Hi Martin,

I have gone through that post and some other posts as well. Can you please confirm my understanding as mentioned below:

- For Windows I can use VLC ActiveX to stream an IP camera over RTSP.
- For Linux I might need to make my own Video EWO using QT Libraries to stream an IP camera, as it is not provided by standard WinCC OA installation.

If above understanding is correct then, how complicated is to make your own video EWO using QT Libraries for Linux. Are there any help files/manuals/templates from ETM to provide a guide line.

BR,

Ilyas.

In this post there is an example of a video player ewo. This should give you an idea how complicated it is.
In the help file there is some documentation (qthelp://wincc_oa/doc/Native_GEDI/EWO.htm) under: Graphics editor (GEDI) -> Complex graphics objects -> EWO (External Widget Object)
