High Efficiency Video Coding ( HEVC ), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality ...
Contents. Help:Media (audio and video) All modern browsers will play video ( Theora and WebM) and audio ( Vorbis and MP3) files from Wikipedia, no modifications needed. On older iOS, iPadOS, and macOS devices, software decoding will be used. This might be a bit slow compared to what you are used to on such devices.
