How to turn off the automatic video playback of oppo mobile phone?

The video is played by a non-default player. If multiple video players are downloaded, the video player will pop up when the video is opened, and one player will always be selected to play the video, and this player will play the video by default in the later period;

You can go to "Settings > (Application) > Application" to find the player that plays the video by default, clear the default settings, and re-select the player operation when opening the video.

This answer applies to all OPPO models.
