mpegtscrypt

Simple Gstreamer element for MPEG TS cryptography by BISS and AES.

Usage:

For satellite channels that scrambled by BISS:

$ gst-launch-1.0 udpsrc uri="udp://229.1.1.1:3200" ! queue \
               ! mpegtscrypt method="biss" op="dec"  key="111111222222" \
               ! fakesink

For secure trasfering:

In Server:

$ gst-launch-1.0 udpsrc uri="udp://229.1.1.1:3200" ! queue \
               ! mpegtscrypt method="aes256_ecb" op="enc"  key="111111222222" \
               ! udpsink host=229.1.1.2 port=3200

In Client:

$ gst-launch-1.0 udpsrc uri="udp://229.1.1.2:3200" ! queue \
               ! mpegtscrypt method="aes256_ecb" op="enc"  key="111111222222" \
               ! fakesink

TODO:

- Add CCCAM methods to unscrambling of Satellite channels.     
- Operate on the last remaind of TS packet (% 16) in AES algorithm.
- Add other crypto algorithms.
- Add Test Case
