AW: Trouble playing videos with MS DirectShow LC 8

[Tiemo Hollmann TB]

Hi Tim,

hmm, I didn't knew, that this codec is a hardware based codec. Do you think it definitely is tied to special intel hardware and won't run on every hardware and can't be added by a software codec? Btw. It runs also fine on my iMac.

That would be really bad for me, because it was the only codec my Sorenson squeeze offered me for H.264, where I can step frame by frame thru the video, what is a must for my app.

I’m certainly no expert on video encoding but since you used the Intel QSV H.264 encoder I’m wondering if the Livecode implementation of DirectShow does not support that hardware based encoder. You might have better luck and broader compatibilty using something like the default encoder in Handbrake.

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.
