DSC Development Container

This is a development container for Digital Signature of Content (DSC) implementation and testing. It includes VVC VTM (VVCSoftware Video Test Model) encoder/decoder and GStreamer plugins for signing and verifying video streams with digital signatures.

The container provides a complete environment for:

• Encoding and signing video streams using VVC VTM
• Decoding and verifying digitally signed streams
• Testing GStreamer DSC plugins (dscverifier and dscsigner)
• Working with both H.266/VVC and H.264 codecs

This README contains sequential test cases to verify the DSC functionality across different encoding and verification scenarios.

Building the container

docker build -t dsc .

Running the container

docker run \
    --privileged \
    -e DISPLAY \
    --rm \
    -v $(pwd):/app \
    -it \
    dsc bash

Testing functionality

Please, follow it sequentially to ensure you have the data needed in the previous step.

Make VVC VTM to encode and sign a stream

cd /root/VVCSoftware_VTM/bin
./EncoderAppStaticd \
    -i \
    /app/AUD_MW_E.raw \
    -wdt \
    176 \
    -hgt \
    144 \
    -fr \
    30 \
    -f \
    5 \
    -c \
    ../cfg/encoder_randomaccess_vtm.cfg \
    -c \
    ../cfg/sei_vui/digitally_signed_content.cfg  

Make VVC VTM to decode and verify a stream

cd /root/VVCSoftware_VTM/bin
./DecoderAppStaticd \
    -b \
    ./str.bin \
    -o \
    ./decoded_str.yuv \
    --KeyStoreDir=../cfg/keystore/public \
    --TrustStoreDir=../cfg/keystore/ca \
    --TraceFile=/tmp/sei_dsc_trace_decode.txt \

Make GStreamer to verify a stream

Make VVC VTM to encode without signing a stream

cd /root/VVCSoftware_VTM/bin
./EncoderAppStaticd \

    5 \
    -c \
    ../cfg/encoder_randomaccess_vtm.cfg \
    -b \
    str-no-dsc.bin

Make GStreamer to sign a VVC VTM stream

cd /root/VVCSoftware_VTM/bin

Make VVC VTM to decode and verify GStreamer signed stream

cd /root/VVCSoftware_VTM/bin
