To set up the GS DRM (of Cifra) for a stream or for files in a VOD location, add the drm parameter as follows:

stream example_stream {
  input fake://fake;
  meta drm_id 03a...022;
  drm gsdrm keyserver=;
file drm {
  path /storage/vod;
  protocols dash hls;
  drm gsdrm keyserver=;


  • keyserver (required) — the URL of the key server GS DRM.. he

Additionally, for streams you can specify the meta drm_id option — it will be used instead of the stream name in requests for playback.

When a VOD file at /storage/vod/content.mp4 is accessed, Flussonic will read the ContentId from the /storage/vod/content.mp4.gsdrm_id file.
