eXtra-fast Essential Video Encoder (XEVE)

The eXtra-fast Essential Video Encoder (XEVE) is an opensource and fast MPEG-5 EVC encoder.

MPEG-5 Essential Video Coding (EVC) is a future video compression standard of ISO/IEC Moving Picture Experts Grop (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.

Quality comparison

MPEG-5 Baseline Profile vs. MPEG-4 AVC/H.264

MPEG-5 EVC Baseline Profile can show 2-times better coding gain over MPEG-4 AVC/H.264 codec and superior quality on the same bitrate

MPEG-5 Main Profile vs. HEVC/H.265

MPEG-5 EVC Main Profile can show 2-times better coding gain over HEVC/H.265 codec and superior quality on the same bitrate

How to build

Linux (64-bit)

• Build Requirements

  • CMake 3.5 or later (download from https://cmake.org/)
  • GCC 5.4.0 or later

• Build Instructions for Baseline Profile

  $mkdir build
  $cd build
  $cmake .. -DSET_PROF=BASE
  $make
  

  • Output Location
    • Executable application (xeveb_app) can be found under build/bin/.
    • Library files (libxeveb.so and libxexeb.a) can be found under build/lib/.

• Build Instructions for Main Profile

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

  • Output Location
    • Executable application (xeve_app) can be found under build/bin/.
    • Library files (libxeve.so and libxexe.a) can be found under build/lib/.
  • Application and libraries built with Main Profile can also support Baseline Profile operation.

Windows (64-bit)

• Build Requirements

  • CMake 3.5 or later (download from https://cmake.org/)
  • MinGW-64 or Microsoft Visual Studio

• Build Instructions for Baseline Profile

  • MinGW-64

    $mkdir build
    $cd build
    $cmake .. -G "MinGW Makefiles" -DSET_PROF=BASE
    $make
    

  • Microsoft Visual Studio

    $mkdir build
    $cd build
    $cmake .. -G "Visual Studio 15 2017 Win64" -DSET_PROF=BASE
    $make
    

    You can change '-G' option with proper version of Visual Studio.

• Build Instructions for Main Profile

  • MinGW-64

    $mkdir build
    $cd build
    $cmake .. -G "MinGW Makefiles"
    $make
    

  • Microsoft Visual Studio

    $mkdir build
    $cd build
    $cmake .. -G "Visual Studio 15 2017 Win64"
    $make
    

    You can change '-G' option with proper version of Visual Studio.
  • Application and libraries built with Main Profile can also support Baseline Profile operation.

How to use

XEVE supports all profiles of EVC. Examples of configure file of coding structures are provided in cfg folder.

OPTION	DEFAULT	DESCRIPTION
-i, --input	-	file name of input video
-o, --output	-	file name of output bitstream
-w, --width	-	pixel width of input video
-h, --height	-	pixel height of input video
-z, --hz	-	frame rate (Hz)
-f, --frames	-	maximum number of frames to be encoded
-q, --op_qp	32	QP value (0~51)
-d, --input_bit_depth	8	input bitdepth (8, 10)
-m, --parallel_task	0	mumber of threads to be created
--profile	0(base)	index of profile(0:baseline, 1:main)
--config	-	file name of configuration
--rc_type	-	0 (rc_off) / 1(rc_on)
--bps	-	bits per second
--vbv_msec	-	vbv size in msec
--preset	reference	preset of xeve (fast, medium, slow, reference)

More optins can be found when type xeve_app only.

Example

$xeve_app -i RaceHorses_416x240_30.yuv -w 416 -h 240 -z 30 --rc_type 0 -o xeve.bin
