Abstract: Implementations of the disclosure provide for video stream encoding system with live crop editing and recording. In one implementation, the method comprises receiving, by a camera device, an input video stream depicting an image. A first video stream and a second video stream are generated based on the input video stream. A crop instruction associated with the image is received based on user input. A region of interest in the first stream is determined based on the crop instruction. The first stream depicts a full field of view of the image associated with the input video stream. A cropped view presentation of the full field of view is generated to associate with the second stream in accordance with the region of interest. Thereupon, a portion of the cropped view presentation of the second stream is provided for display at a network device.

Abstract: A camera device comprising a body housing an image-capturing component and a first and second encoder component and a second encoder component coupled to the image capturing component is provided. The body has a first and a second surface opposite the first surface that is arranged to pitch the body at a determined angle upward with respect to a substantially planar surface upon which the camera device is placed. The image-capturing component is to capture an input stream in a viewing direction of the camera device. The first encoder component to generate a first video stream based on the input stream and the second encoder component to generate a second video stream based on the input stream. The first video stream depicts a full field of view (FOV) of an image associated with the input stream and the second video stream depicts a cropped view presentation of the full FOV.
