Recording in VST(Video storage toolkit)

Thanks. I was able to download the video of variable length. However it was downloaded in “ts” format, how can i get the mp4 format.

API i used:
http://1.2.3.4:30000/api/v1/storage/file/sensorid?startTime=2024-07-22T09:43:00.000Z&endTime=2024-07-22T09:53:00.000Z

Anything else to be added here?
