Trouble playing videos with MS DirectShow LC 8

Hello,

 

With LC 8.1.2 I changed the video standard in my programs from Quicktime to
the new standard interface DirectShow on Windows. 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
