Playing video within WinCCOA - Linux

[nedzad]

Hello,

Do you have any suggestions how to play video within WinCC OA 3.15 on OpenSuse? For Windows, I used ewo from this link, but it's not working on Linux.

Best regards,
Nedžad

Hello,

The source is included, you should be able to compile the EWO in Linux.

Hello,

Of course, a windows ewo won't work on linux. You have to compile the EWO with our API yourself.

To save you the trouble, i've compiled the ewo for you. (see attachment).

Best regards,

Thanks a lot.

Now I am able to run this ewo, but when I click on any button in panel I get the "Unable to pause" message in log, etc.:

I only have here virtual machines which do not even seem to be able to play video files, but maybe this gstreamer error only occurs on networked files. Try to download the file or use another local mp4 file for testing.

This EWO is just a simple wrapper for underlying QT functionality which seems to rely on gstreamer. Maybe it is a restriction of that.

I got the same error and when I try to play local file:
