Running

This TMC13 codec implementation encodes frame sequences. A single binary contains the encoder and decoder implementation, with selection using the --mode option. Documentation of options is provided via the --help command line option.

Runtime configuration and configuration files

All command line parameters may be specified in a configuration file. A set of configuration file templates compliant with the current Common Test Conditions is provided in the cfg/ directory.

Example

To generate the configuration files, run the gen-cfg.sh script:

mpeg-pcc-tmc13/cfg$ ../scripts/gen-cfg.sh --all

An example script (scripts/Makefile.tmc13-step) demonstrates how to launch the encoder, decoder and metric software for a single input frame. The VERBOSE=1 make variable shows the detailed command execution sequence. Further documentation of the parameters are contained within the script.

The following example encodes and decodes frame 0100 of the sequence Ford_01_q_1mm, making use of the configuration file cfg/lossy-geom-no-attrs/ford_01_q1mm/r01/encoder.cfg and storing the intermediate results in the output directory experiment/lossy-geom-no-attrs/ford_01_q1mm/r01/.

mpeg-pcc-tmc13$ make -f $PWD/scripts/Makefile.tmc13-step \
    -C experiment/lossy-geom-no-attrs/ford_01_q1mm/r01/ \
