Building

Bash scripts can be use to build mpeg-pcc-tmc2 project:

• build.sh: build solutions.
• clear.sh: clear solututions.

OSX

• mkdir build
• cd build
• cmake .. -G Xcode
• open the generated xcode project and build it

Linux

• mkdir build
• cd build
• cmake ..
• make

Windows

• md build
• cd build
• cmake .. -G "Visual Studio 15 2017 Win64"
• open the generated visual studio solution and build it

External dependencies

The external dependencies must be download and build:

• HM-16.20+SCM-8.8 (apply pcc_me-ext_for_HM-16.20+SCM-8.8.patch on it stored in \dependencies\hm-modification ).

  svn checkout https://hevc.hhi.fraunhofer.de/svn/svn_HEVCSoftware/tags/HM-16.20+SCM-8.8/ external/HM-16.20+SCM-8.8-3DMC;
  cd external/HM-16.20+SCM-8.8-3DMC svn patch ../../tmc2_r7.0/dependencies/hm-modification/pcc_me-ext_for_HM-16.20+SCM-8.8.patch

• HDRTools

• pcc_distortion

Running

Configuration files are provided in the cfg directory to aid configuring the encoder. The general pattern of usage is illustrated below, where multiple configuration files control different aspects of the test conditions.

NB: parameters set in one configuration file override the same parameter in earlier files. ie. order matters.

Further help text describing option usage is available using "./bin/PccAppEncoder --help" or "./bin/PccAppDecoder --help".

PccAppEncoder

./bin/PccAppEncoder \
	--configurationFolder=cfg/ \
	--config=cfg/common/ctc-common.cfg \
	--config=cfg/condition/ctc-all-intra.cfg \

PccAppDecoder

./bin/PccAppDecoder \
	--compressedStreamPath=S26C03R03.bin \
	--videoDecoderPath=../external/HM-16.16/bin/TAppDecoderStatic \
