Problem with default video player

Hello,

The default video player in MyTVOnline does not work properly when it comes to video file .MKV with AAC in Main profile. (video and sound are fast forward)
It works well with AAC in LC profile.
I do not know if it is after the update. In my VOD services, there is a lot of film that works more correctly.
I tested with MX player or VLC since MyTVOnline it works properly.
Thanks for your help,

Hello,
I did tests with movies that worked well before the update and it does not work properly anymore.
Since the update, the file in MKV with AAC in main profile does not work anymore.
Is it possible to correct the problem?
Thank you

Hello,

No more feedback of Formuler support,

I decide to see if others have the same problem with the default player. (with VOD in IPTV services)
I said it worked well before the last update.
There must be a codec problem following this update.
Here are some details about the properties of the files.

Thanks for your help.
