I know how to trigger a video intelligence request for object tracking / object detection with Google Cloud as following :
video_client = videointelligence.VideoIntelligenceServiceClient()
features = [videointelligence.enums.Feature.OBJECT_TRACKING]
operation = video_client.annotate_video(gs_video_path, features=features)
How can I trigger the same function for brand detection, scene detection, OCR, speech recognition and celebrity recognition ?
