AW: who has experience with mp4 videos on windows?

[Tiemo Hollmann TB]

Hello Nicolas,

thanks for your idea, but my app doesn't updates the codec.
But nevertheless, I just found a newer version of the LAV filters - worth a
try.

Tiemo,

My advice is probably of no use but...

Could it be the solution is updating the codecs?

What you described reminded me very much of "MX Player" updates (a popular
video player for Android). Every time after an update, some videos open up
with no sound and a "This Audio Format AC3 Is Not Supported" error  message.
Updating the codecs is always the
(irksome!) solution; licensing issues, I think?

Anyway, my 3 yen's worth... which is what's hanging around in my wallet
now... and getting rid of 1-yen coins is only a little less of a pain than
Googling for the latest codecs.
