LUNA PASS VIDEO#
LUNA PASS VIDEO allows you to create a video file based on the received set of frames and process it on the client side for further work with the file (saving, transfer, etc.).
LUNA PASS VIDEO performs splicing together a video file from a webcam or mobile app camera in a single session using the codec set in the settings.
The video file is assembled from the last N frames from the end of the session.
The number of frames from which the gluing should be performed is regulated in LUNA PASS settings.
- In case if less than N frames are received during the session, LUNA PASS performs gluing from the available number of frames.
- In case if more than N frames are received during the session, LUNA PASS performs gluing from the last N frames from the end of the session.
Video file gluing from frames is performed for all sessions independently of the result of estimations performed in LUNA PASS API or expiration of the number of attempts to pass certain checks.
To process the received video files it is necessary to create a file task.py (for example, by analogy with example_redis_task.py) and realize in it the logic of processing the received videos.
The name of the file directly depends on the parameter args.workerTask, which is set in the configuration of LUNA PASS API.
In case of reconnection at WebSocket session break, LUNA PASS VIDEO forms one common video file for one session ID and saves it to the storage.
