My fault, obviously some people of you, who wanted to make the test couldn' even play my video. I forgot that a standard Windows machine doesn't have a codec for h.264 videos on board. So you would have had to install a codec (like the LAV filters). I now modified my test program, so that you can choose any of your own video files on your computer. So, if you would like to do another test, read below, my previous posting Thanks Tiemo

Up to now, I only have two customers with this issue and so it is hard to search for "exotic" similarities. If you would like to help me and make a test for me, please download my little test program from 1. Open the LC 8.1.4 program and klick the left button, it should play a video, which was unpacked in the same dir as the livecode file in the left window and make a screenshot in the right window 2. if the right window only is black (screenshot was not successful), try to make a screenshot with "Alt Gr" + "Print" of the left video window and paste it into word or other program to see, if windows can take a screenshot. 3. Do the same with the right button (without videobuffer) If any of these test cases didn't produced a screenshot of the video, I would like to get your system informations (I will delete them right after evaluation) and the notice, which case didn't produced a screenshot. If both test cases produced a screenshot, you don't have to send me any notice. You can retrieve the system informations here: - press Windows-Key + R. - type "msinfo32" - Choose menu File - Export, enter a filename Systeminformationen_xy.txt - send me this file as PM If you have concerns about your privacy, please delete all personal information from the log file, like your IP number, you name of the machine or whatever you want. Thank you for your help.

One essential feature of my program is, that the user can take screenshots from the video, edit and save them. Today I got the second customer call with a Win 10 machine, who can't take screenshots from my LC videos. The video screen is just black on the taken screenshot. This issue does not only happen with the build in LiveCode screenshot feature, but also, if they take a screenshot with the windows print key or other screenshot tools. Up to now, this issue happens only at 2 customers, on all other Win 10 machines, taking a video screenshot works fine. The alwaysBuffer of the videoPlayer is set to false (setting it to true, I don't see any video playing) I also checked to disable the Kaspersky AV on the client computer (Kaspersky has a feature to prevent screenshots), but without success. Btw. the old version of my program with the quicktime player works fine on these machines. I googled a lot, but didn't found any related issues in the net, so I assume, it must be related to the LiveCode implementation of the directShow videoPlayer. But in combination with any special hardware or software setting on these two computers. Has anybody already experienced similar issues or has any shot in the dark, what system options, drivers, other tools in combination with LiveCode could have an influence on taking a screenshot? Any idea, what I could check for is welcome Tiemo _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
