dashdrm-mp4ff

Custom Streamlink plugin for DRM-protected MPEG-DASH streams.

This project is based on titus-au/streamlink-plugin-dashdrm, which itself is based on Streamlink's dash.py.

Install mp4ff-decrypt

go install github.com/Eyevinn/mp4ff/cmd/mp4ff-decrypt@latest

Make sure the Go bin directory is in your PATH, then verify:

mp4ff-decrypt -h

If you do not want to use mp4ff-decrypt, you can still use the plugin without --dashdrm-mp4ff-use-mp4ff.

Usage

Run Streamlink with the local plugin directory:

streamlink --plugin-dirs "plugin" "dashdrm://https://example.com/live.mpd" best

With mp4ff-decrypt and kid:key pairs:

streamlink \
  --plugin-dirs "plugin" \
  --dashdrm-mp4ff-use-mp4ff \
  --dashdrm-mp4ff-decryption-key "kid1:key1,kid2:key2,kid3:key3" \
  "dashdrm://https://example.com/live.mpd" \
  best

Notes:

• Keys can be provided as raw keys or as kid:key.
• When kid:key pairs are provided, the plugin parses the manifest and matches each track with the correct key.
• The plugin file is plugin/dashdrm_mp4ff.py.

gen.py

gen.py is a small helper that reads channels from vault.json, lets you pick one interactively, and prints the full Streamlink command.

Install the helper dependency:

uv sync

Create your own vault.json from vault.json.example, then run:

python gen.py

The expected structure is:

{
  "channels": [
    {
      "id": "channel-id",
      "number": "1",
      "name": "Channel name",
      "mpd_url": "https://example.com/live.mpd",
      "keys": [
        "kid1:key1",
        "kid2:key2"
      ]
    }
  ]
}
