Description
Can I calculate the FPS for every second with the raw data I receive in OnVideoMediaReceived ?
In some seconds I receive 5 data arrays with varying length (e.g. 10486, 10817, 9185),
some seconds I receive 10 arrays, some 15...
Attaching a file from logs of a 43 seconds video
This way I can create a separate video file for each major FPS change, and in the end merge them together with FFMPEG.

Research direction
Start with OnVideoMediaReceived and the attached teams-recording-bot.log; compare the number and lengths of arrays received in each one-second interval. Done means establishing whether the raw data supports reliable per-second FPS detection for variable-FPS segmentation and the proposed FFmpeg merge.
