Variable sound drift when playing MP4 in VOD application
I have a .mp4 file which reads perfectly with chrome's builtin player through http (including instant seeking).
When I play it with vlc through rtmp, the sound is about 1 sec early. When I use wowza's builtin player, the sound is about 3 sec late (rtmp or hds).
The file has been processed with MP4Box, and I also tested with qt-faststart.
Is there a way to have the sound in sync when using wowza?
TIA

Hello Greg.
Try adding the following property to the Streams/Properties in [install-dir]/conf/[application]/Application.xml (be sure to get the correct properties container - there are several in Application.xml):
You can increase/decrease 250 as needed to get the audio synced up.
I hope this helps.
Kind regards,
