[FFmpeg-user] Question about audio video synchronization in containers

Dear Sirs and Madams,

I have a question about containers and synchronization of the contained
video and audio streams and hope someone can provide me some basic

How can I guarantee that the muxed/interleaved streams are synchronized in a
container so that there is no delay when played?
Video has timestamps like PTS and DTS. Do audio streams have that too?
Does a container have timestamps or does it work with timestamps provided by
the streams?
Is there a general way of synchronization for all containers (AVI, MPEG, MKV

Thank you for your time, help and any information or hint that could help me
to understand that matter.

Have a nice day
