A method includes: receiving, by a computer, a user input corresponding to selection of a link associated with an address; determining, by the computer, that the address would not fit in an address bar of a browser displayed on a screen of the computer; and based on the determination that the address would not fit in the address bar of the browser, displaying, by the computer, in the address bar of the browser, a first element of the address and at least part of a second element of the address, including displaying a first portion of the second element of the address and an ellipsis indication representing a second portion of the second element of the address. The display of the first element of the address is visually distinguished from the display of the first portion of the second element of the address.

An example device includes memory and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to receive a first slice header syntax element for a slice of the video data and determine a first value for the first slice header syntax element, the first value being indicative of whether dependent quantization is enabled.

A method and wearable camera for encoding video captured by a wearable camera determines a centre of rotation for an image frame to be encoded. The centre of rotation relates to a rotation of the wearable camera at the time of capturing the video and the image frame comprises multiple groups of pixels. Furthermore, compression levels are set for the multiple groups of pixels of the image frame. The compression levels for the multiple groups of pixels of the image frame are set such that a level of compression increases with a radial distance from the centre of rotation. The image frame is encoded using the compression levels.
