Python (plus C) reimplementation of the captioncompiler utility, used to create caption files for source-engine games.
It is intended to be a standalone tool, usable without needing to download and compile the whole source-engine codebase.
The crc32 utility is copied straight from the source engine 2013 implementation, and must be compiled before use:
cd crc32/
gcc valve_crc32.c -o valve_crc32
Print the header of a closedcaption.dat file:
python valve_captioncompiler.py closedcaption.dat
Print the header and the directory of a closedcaption.dat file:
python valve_captioncompiler.py -d closedcaption.dat
Create a new .dat file from a source file with the proper formatting (see the official documentation):
python valve_captioncompiler.py -c closecaption_source.txt newcaption.dat
