TRVCamera.OnGetVideoStreamIndex

Allows to choose a video stream to play.

property OnGetVideoStreamIndex: TRVGetMediaStreamIndexEvent;

This event occurs before playing a video file, if it is played using FFmpeg.

This event may be useful if a video file contains more than one video stream. It is a very rare case.

If the event is not processed, the first video stream is played.

Warning: this event is called in a thread context.

You cannot change a video stream while the video is played: you need to restart video.
