AVI is a derivative of the Resource Interchange File Format (RIFF), which divides a file's data into blocks, or chunks. Each chunk is identified by a FourCC tag. An AVI file takes the form of a single chunk in a RIFF formatted file, which is then subdivided into two mandatory chunks and one optional chunk. The first sub-chunk is identified by the hdrl tag. This sub-chunk is the file header and contains metadata about the video, such as its width, height and frame rate. The second sub-chunk is identified by the movi tag. This chunk contains the actual audio/visual data that make up the AVI movie. The third optional sub-chunk is identified by the idx1 tag which indexes the offsets of the data chunks within the file.
AVI format uses the support of Resource Interchange File Format (RIFF) where the whole data is stored into chunks and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag and it can decode the chunk containing metadata for the video and the second chunk gets recognized by the movi tag and it contains the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.

WebM benefits from being designed for use on the modern web, rather than for local use. This means the format is specifically designed for the wide range of devices that are used to access the web, from Smart Phones to Powerful PCs. The video element of the file is encoded using VP8 video codec and the audio element of the file is encoded using the Vorbis audio codec.
Encoding and deciding in WEBM format is possible while using the ffvp8 software or libvpx from the Google support. When it comes to the Android support a version of 2.3 (Gingerbread) and above allowing playback of WEBM format can be used for encoding and decoding. Back in 2001 using Rockchip a full hardware implementation of 1080p VO8 encoding was made possible.
