eXtra-fast Essential Video Decoder (XEVD)

The eXtra-fast Essential Video Decoder (XEVD) is an opensource and fast MPEG-5 EVC decoder.

MPEG-5 Essential Video Coding (EVC) is a video compression standard of ISO/IEC Moving Picture Experts Group (MPEG). The main goal of the EVC is to provide a significantly improved compression capability over existing video coding standards with timely publication of terms. The EVC defines two profiles, including "Baseline Profile" and "Main Profile". The "Baseline profile" contains only technologies that are older than 20 years or otherwise freely available for use in the standard. In addition, the "Main profile" adds a small number of additional tools, each of which can be either cleanly disabled or switched to the corresponding baseline tool on an individual basis.

  • GCC 5.4.0 or later

• Build Instructions

  $mkdir build
  $cd build
  $cmake ..
  $make

  • Output Location
  • Executable application (xevd_app) can be found under build/bin/.

  $make

  • Output Location
  • Executable application (xevd_app) can be found under build-arm/bin/.
  • Library files (libxevd.so and libxevd.a) can be found under build-arm/lib/.

How to generate installer

Linux (64-bit)

• Generation of DEB packages instructions

  • Follow build instruction and build the project
  • Generate DEB packages

    $make package

    or

    cpack -G "DEB"

  • Output
  • Base DEB package for Baseline Profile:
    • package: xevd-base-dev_1.0.0_amd64.deb
    • checksum file: xevd-base-dev_1.0.0_amd64.deb.md5
  • Developer DEB package for Baseline Profile::
    • package: xevd-base_1.0.0_amd64.deb
    • checksum file: xevd-base_1.0.0_amd64.deb.md5 generated.
  • Base DEB package for Main Profile:
    • package: xevd-main-dev_1.0.0_amd64.deb
    • checksum file: xevd-main-dev_1.0.0_amd64.deb.md5
  • Developer DEB package for Main Profile:
    • package: xevd-main_1.0.0_amd64.deb
    • checksum file: xevd-base_1.0.0_amd64.deb.md5 generated.

• Generation of RPM packages

  • Follow build instruction and build the project
  • Generate RPM packages

    cpack -G "RPM" ..

• Generation of ZIP archives

  • Follow build instruction and build the project
  • Generate ZIP archive

    cpack -G "ZIP" ..

Windows (64-bit)

• Requirements

  • NSIS 3.08 or later (download from https://nsis.sourceforge.io/Download)

• Generation of NSIS windows installer instructions

  • Follow build instruction and build the project

  • Generate NSIS Windows installer

  • Command Prompt for Visual Studio

    • Go to the build directory and issue the following command

      msbuild /P:Configuration=Release PACKAGE.vcxproj

  • Visual Studio IDE

    • Open up the generated solution (XEVD.sln)
    • Change build type from Debug to Release
    • Go to the Solution Explorer, then select and mouse right click on the PACKAGE project located in CMakePredefinedTargets folder
    • Choose Build item, when a pop down menu appears

    As a result CPack processing message should appear and NSIS installer as well as as checksum file are generated into build directory.

  • MinGW-64

    • Go to the build directory and issue the following command

      $make package

  • Output:

  • Baseline Profile:

    • xevd-base-1.0.0-win64.exe
    • xevd-base-1.0.0-win64.exe.md5

  • Main Profile:

    • xevd-main-1.0.0-win64.exe
    • xevd-main-1.0.0-win64.exe.md5

      How to use

      XEVD supports main and baseline profiles of EVC.

More options can be found when type xevd_app only.

Example

$xevd_app -i input_bitstream.evc -o output_video.yuv
