Can you record again from your webcam and then play the file? Does the file you record is the same compression algorithm as the file that doesn't work?

Hi Kfir,

thank you for your reply! :)

sorry, English isn't my mothers tongue...

When playing other videos there is no problem with the sound.

What did you mean with

=C2=A0 =C2=A0"Can you record now a picture with the webcam and play i= t with sound after?"


mcc


You said that this file is a recording of the webcam wit= h sound.
Can you record again from your webcam and then play the file?<= br>Does the file you record is the same compression algorithm as the file t= hat doesn't work?
