Making some further tests, I discovered that there must be a relation to mp4 video files. I tested the same standalone with an old avi file and that worked, but not with some different mp4 files But it can't be something in general, because the mp4 file can be played fine with the same standalone on my W10 machine. So I am still searching for an idea, what could be different on my machine to "all" others.

I recoded all videos to mp4 with Intel QSV H.264. On my developing W10 machine everything works fine in the IDE and standalone. Now after release it looks like my developing machine is "the only one" which can play the new videos in my new LiveCode program. On a W7, W8 and other W10 machine I get the error "could not create movie reference" when setting the filename of the player object. Actually the DirectShow standard should be available from W7 to W10 and when just double clicking the video, it can be played on all those other machines with the standard video player, so it doesn't seem to be an codec issue. On the other hand something from the environment must be different on my developing machine. I also tried to build a new standalone with LC 9.0 dp3, but testing the standalone it show the same issue. Has anybody any idea, where to start searching? What could be different on my developing machine as on all other machines? Are there any known system requirements for using DirectShow? (which I have set unconsciously on my machine) Thanks for any ideas 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
