Description
Hello!
We are writing a bot application using MS Teams SDK.
Basically we want to record audio and video that comes in H264 Variable Frame Rate format, but when receiving video frames (H264), the resulting file is out of sync with the related audio stream.
The timestamps are checked, but the video file is always with less frames than expected.
Our bot performs streams management by application side (local self-host server).
It's based on .NET FW and Microsft.Skype.Bots.Media library. The video streams are in H264 format.
However we get unsync audio/video due to the fact that Teams sends this video in variable frame rate. Is there a way to get a syncronized audio/video?

Research direction
The report names no repository file, test, or entry point, so first determine whether the sample contains the bot's media-stream handling and whether the issue is reproducible there. Trace how H264 video timestamps and audio timestamps are consumed; done would require a reproducible fix or clear guidance for keeping the streams synchronized.
