  1. HEVC Reference softwareHM 4.0 광운대학교 영상처리 시스템 연구실 조현호 (idjhh@kw.ac.kr)

  2. TortoiseSVN • A Subversion client • http://tortoisesvn.tigris.org/ • Latest version • TortoiseSVN 1.71 • System requirements • WinXPwith SP3, Vista or later • Windows installer version 3.1 or later • 서브 버전 설치

  3. HM 4.0 download • 1. HM-4.0 코드를 저장할 디렉토리 생성 • 2. 디렉토리 안으로 이동한 후 마우스 오른쪽 버튼을 클릭하여 TortoiseSVN->Export • Repository에 다음을 입력 https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/HM-4.0 • 3. OK 버튼을 클릭하여 다운로드

  4. HM-4.0 소스 파일 디렉토리 구성 • build • HM_vc9.sln • Microsoft Visual Studio Solution • cfg • per_sequence • encoder_lowdelay_loco.cfg • encoder_lowdelay.cfg • source • App • TAppDecoder • TAppEncoder • utils • Lib • TAppCommon • TLibCommon • … lowdelay => I and P slice

  5. Encoder (with VS 9.0) • 1. File -> Open -> Project/solution • ./build/HM_vc9.sln 파일 열기 • 2. TAppEncoder를 “Set as StartUP Project” • 3. HM-4.0 폴더와 동일 경로 origCfP폴더 생성 • Test 영상은 origCfP폴더에 저장 • orgCfP/BasketballPass_416x240_50.yuv • 4. HM-4.0 폴더 내에 working 폴더 생성 • 이 폴더에 결과를 저장할 예정 (result.yuv)

  6. Encoder (with VS 9.0) • 5. TAppEncoder의 Property Pages에서 Debugging 속성에서 CommandArguments와 Working Directory를 다음과 같이 설정 • Working Directory • ../../working • HM-4.0-ref\build\vc9 기준으로 볼 때 working 디렉터리의 상대 경로임 • Command Arguments • -c ../cfg/encoder_lowdelay_loco.cfg -c ../cfg/per-sequence/BasketballPass.cfg • working 디렉터리를 기준으로 cfg파일의 상대 경로를 입력하면 됨.

  7. Encoder (with VS 9.0) • 6. Encoder 설정 변경 • HM-4.0-ref/cfg내에 있는 여러 cfg파일을 사용함 • lowdelay/lowdelay_P/randomaccess • loco/high efficiency (loco가 안 붙은 cfg) • HM-4.0-ref/cfg/per-sequence 에서도 일부 설정 변경 가능함

  8. Encoder output

  9. Decoder • 1. TAppDecoder를 Set as StartUP project로 설정 • 2. TAppdecoder의 Property Pages에서 Debugging 속성에서 CommandArguments와 Working Directory를 다음과 같이 설정 • Working Directory • ../../working • HM-4.0-ref\build\vc9 기준으로 볼 때 working 디렉터리의 상대 경로임 • Command Arguments • -b str.bin –o result.yuv • working 디렉터리를 기준으로 상대 경로를 입력하면 됨.

  10. Decoder output • working directory에 result.yuv가 생성됨 • mismatch checking • Beyond compare or Ultra edit

  11. YUV player • PYUV • Resolution • YUV, 4:2:0 • Extra settings : 10bit

  12. DF, SAO and ALF (Decoder) • TLibCommon\TComLoopFilter.cpp • loopFilterPic() • TLibCommon\TComAdaptiveLoopFilter.cpp • SAOProcess() • ALFProcess()

  13. Q and A • Useful links • A new version (d5) of the HEVC working draft 4 (JCTVC-F803) was uploaded to the document management site and is now available (http://phenix.int-evry.fr/jct/doc_end_user/current_document.php?id=3286). • JCT-VC mailing list • http://mailman.rwth-aachen.de/mailman/listinfo/jct-vc • https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/ (web browser)
