Hello,
Thank you for helping.
A compressed file (link) was created with all files involved in this test. As announced no sound was available in the video file. This problem is not alone : I tried to read the video first with MediaPlayerCenter and the reading was not accepted. Then I tried Ax-Lite-video Player : it was OK (excepted sound) but with a message and no indication of the time lenght. I made an EasyBrake conversion on the initial video and all was OK (excepted the sound). The initial video is named "test.mp4" and the name for the EasyBrake video is "test_3jjpg3.mp4".
I don't know if there is a link between the missing sound and some corrupted items/indexes in the initial video.
Thank you again for testing.
Best regards
