High Efficiency Image File Format (HEIF and HEIC)
High Efficiency Image File Format (HEIF and HEIC) is a container format for bitstreams coded by the High Efficiency Video Coding (HEVC) standard. Note that there is a subtle difference between HEIF and HEIC. HEIF is a file format for storing individual HEVC bitstreams of still images while the HEIC format is tailored to store […]

Ogg Theora Video Coding Standard and Compilation for Windows
Introduction Theora video coding standard released in 2008 by Xiph.Org Foundation, and its specifications are here . Theora’s code sources are here . Notice that the ffmpeg tool by default supports Theora encoding ‘-c:v libtheora‘ (provided that in the configuration of ffmpeg set –enable-libtheora), but the output stream is not played, ffplay reports […]
Dirac Video Coding De-Facto Standard
Introduction Dirac is a hybrid motion-compensated video coding standard that can be used without the payment of license fees. Dirac was released at around 2008. Dirac specification Typical hybrid video coder: taken from the paper “AV1 and VVC Video Codecs: Overview on Complexity Reduction and Hardware Design”, by MARCEL CORRÊA et al. Some features of […]
Scalable Coding of SHVC with SHM Reference Codec
Download & Build Encode and Decode Base Layer Encode and Decode Dual SNR Performance Results Introduction Scalable video coding is coding of video in multiple layers, where each layer represents a different quality representation of the same video scene. The base layer (BL) is the lowest quality representation. One or more enhancement layers […]
LCEVC – New Scalable Video Standard
How Build and Run EVC Codec How Build and Run EVC Decoder In my opinion one of the reason why scalable video is non-popular in commercial applications – most of hw decoders in GPU cards don’t support scalable video because it’s complex and serial in virtue. Real-time decoding of scalable video by sw-encoders is […]
