I am running VST with an IP camera as input (rtsp).

Questions:

  1. Record the stream with1 hour clips. Till now i have seen it can record only 60 seconds clips. Is there a way to increase it or 60 seconds is the only option
  2. The files are save as “.mkv” . Is there an option to save it as “.mp4”, if yes how can it be done.

Yes, VST will record to 60 seconds clips with “.mkv” format. But you can request the stored video from VST with REST API. Can you share more background on your request?

Thanks for your reply. I want to record with the format “mp4” and duration of each clip to be 30 minutes. Is it possible?

You can’t change the format to “mp4” when VST store the camera video. But you can request to download “mp4” file from VST with REST API on x86 dGPU platform. Which platform are you working on? Jetson or x86 dGPU?

Thanks, I am running on x86 dGPU. Can i request the API to get longer (60 min) videos continuously.?

7

Yes, you can set the start time and end time when request the stored video.

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?

Add container=mp4 to your url to make it 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&container=mp4

I am seeing a weird behaviour with recording streams. For the same recording i am seeing different size of video recordings. All the videos are of 60 seconds and of ~30MBs.

But one video seems to be of very large size

What might be the cause of this behaviour
