Extract MISB 601 KLV data from MPEG-TS stream (STANAG 4609).
KLV Data is adapted from https://github.com/paretech/klvdata.
The code changes include the following:
- Ignore errors (write -1000 or -2000 as value).
- Output readable value when printing structure.
- Adding CRC validation to packet.
MPEG-TS extraction is partly implemented, many unneeded fields are not extracted.
Packet ID extraction doesn't seem to be correct when comparing to FFMPEG.
The code is exposed a CLI but can be used as a package to extract KLV data.
Clone the repository.
Use an IDE such as PyCharm.
Create a virtual environment fro the project using python 3.6+.
No additional dependencies are required.
The code can run on entire MPEG-TS file or extracted KLV binary file.
The extract KLV binary use the following:
- Using tool such as ffprobe get the mapping of KLV stream, e.g. 0:3
- Using tool such as ffmpeg copy the KLV stream to file, e.g.:
ffmpeg -i [video-name].ts -map 0:3 -c copy -f data [video-name].klv
run.py is a CLI for parsing klv/mpeg-ts files.
As output can be large, depending on input file, it is advised to pipe to log file.
python run.py -f [file.klv] -kpython run.py -f [file.ts]
