AW: AW: Trouble playing videos with MS DirectShow LC 8

[Tiemo Hollmann TB]

... and as I mentioned, the videos play fine on all machines outside of LiveCode in the standard platform videoPlayer, what says to me that it can't be a codec issue - as far as I see

Hi Jacque,

that's what I also already thought of. But I haven't found yet, how/where I could check for it. I have an old nice tool, called gspot, which usually tells me everything about any video, but it doesn't work with theses H.264 mp4's.  I was on the intel site and downloaded a media sdk, installed it on one of those not working machines, but without success. But actually I don't even know, if that codec is part of that media sdk, they don't describe the detailed content. So it was a shot into the dark and I didn't found yet a dedicated download for that codec.

Tiemo

Do the other machines have the mp4 codec installed? Most versions of Windows didn't ship with it, you had to install it separately.
