It applies to version of the software. 1 General Information Reference software is being made available to provide a reference implementation of the draft HEVC standard being developed by the Joint Collaborative Team on Video Coding (JCTVC) regrouping experts from ITUT SG 16 and ISO/IEC SC29 WG11. One of the main goals of the reference software is to provide a basis upon which to conduct experiments in order to determine which coding tools provide desired coding performance. It is not meant to be a particularly efficient implementation of anything, and one may notice its apparent unsuitability for a particular use. It should not be construed to be a reflection of how plex a productionquality implementation of a future HEVC standard would be. This document aims to provide guidance on the usage of the reference software. It is widely suspected to be inplete and suggestions for improvements are wele. Such suggestions and general inquiries may be sent to the general JCTVC reflector on (registration required). Bug reporting Bugs should be reported on the issue tracker set up at 2 Installation and pilation The software may be retrieved from one of the following SVN servers (mirrored): ? ? Project files are provided for development environments. Environment Location of project file Page: 2 Date Saved: 20210124 MS Visual Studio 8 build/ MS Visual Studio 9 build/ Xcode Linux build/linux/makefile 3 Using the encoder Encoder syntax TAppEncoder [h] [c ] [parameter=value] Option Description h Prints parameter usage c Defines configuration file to use. Multiple configuration files may be used with repeated –c options. parameter=value Assigns value to a given parameter, as further described below. Some parameters are also supported by shorthand –* value. Sample configuration files are provided in the cfg/ folder. 4 Encoder parameters File, I/O and source parameters InputFile Defines source YUV file. Default is “”. Shorthand form is –i. Note: Raw image data is stored in YUV files in planar format. When the bit depth of samples is larger than 8, each sample is encoded in 2 bytes (little endian, LSBjustified). BistreamFile Defines coded bit stream file. Default is “”. Shorthand form is –b. ReconFile Defines reconstructed YUV file. Default is “”. Shorthand form is –o. SourceWidth Defines width of source in luma samples. Default is 0. Shorthand form is –wdt. SourceHeight Defines height of source in luma samples. Default is 0. Shorthand form is –hgt. Page: 3 Date Saved: 20210124 InputBitDepth Defines the bit depth of the source YUV file. Default is 8. InternalBitDepth Defines the internal bit depth used for coding. Default is 0 (meaning same as InputBitDepth). OutputBitDepth Defines the bit depth of the reconstructed YUV file. Default is 0 (meaning same as InternalBitDepth). HorizontalPadding Defines horizontal padding of source in luma samples. Default is 0. Shorthand form is –pdx. VerticalPadding Defines vertical padding of source in luma samples. Default is 0. Shorthand form is –pdy. PAD Enables automatic padding of the source to multiples of MAX_PAD_SIZE luma samples. Default is 0 (false). FrameRate Defines frame rate of source. Default is 0. Shorthand form is –fr. FrameSkip Defines number of frames to skip at beginning of source. Default is 0. Shorthand form is –fs. Note: this feature is currently not functional. FramesToBeEncoded Defines number of frames to be encoded. Default is 0 (all). Shorthand form is –f. Unit definition parameters MaxCUWidth Defines maximum CU width. Default is 64. MaxCUHeight Defines maximum CU height. Default is 64. MaxCUSize Defines maximum
