openHEVC

openHEVC is a fork of Libav with only the files needed to decode HEVC content, it was created for research purposes. Most people will not need to use this and should use the libav HEVC decoder available at https://github.com/OpenHEVC/ffmpeg instead (see https://ffmpeg.org/documentation.html for documentation).

openHEVC in combination with GPAC is used in 3 research projects:

What does openHEVC support?

  • Main Profile (all conformance bitstreams except BUMPING)
  • Main 10 Profile (except different combination of luma/chroma bitwidth)
  • Range extension (4:2:2/4:4:4)
    • Bitstream aligned with April 2014 HEVC standard
  • support of SHM4.1 bitstreams

What is the compiling infrastructure?

  • MSVC2013
  • gcc
  • clang

Where is the source code of openHEVC?

Where is the source code of GPAC?

How to compile openHEVC on linux from source code

  • execute these commands
git clone git://github.com/OpenHEVC/openHEVC.git
git checkout hevc_rext
  • install yasm
  • go into OpenHEVC source folder
  • execute these commands
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RELEASE ..
make
sudo make install

How to test openHEVC on linux from source code

  • Prerequisites: SDL or SDL2
  • go into source folder of openHEVC
  • with SDL: cd build; ./hevc -i name_of_annexB_bitstream.(bit,bin,265)
  • with SDL2: cd build; ./hevc_sdl2 -i name_of_annexB_bitstream.(bit,bin,265)
    • add -n to remove the display
    • add -l layer with layer a number to select the layer in a SHVC bitstream
    • add -f xx with xx to select frame-based (0), wpp/tiles (1) or combination of frame-based and wpp (4)
    • add -p to select the number of threads when -f is activated

How to compile gpac with openHEVC on linux

./configure 
make
sudo make install

How to embed HEVC into MP4 file format

  • use i_main, lp_main, ld_main or ra_main bitstreams from http://ftp.kw.bbc.co.uk/hevc/hm-10.0-anchors/bitstreams/
  • MP4Box -add name_of_annexB_bitstream.(bit,bin,265) -fps 50 -new output.mp4
    • where fps specifies the framerate (in the case of BQMall_832x480_60_qp22.bin the framerate is 60)
  • MP4Client output.mp4 # to play HEVC mp4 content

How to embed HEVC into TS

cd bin/gcc
./mp42ts -prog=hevc.mp4 -dst-file=test.ts
MP4Client test.ts # to play HEVC transport streams
