JWT access token. Paste the token only; the Bearer prefix is added automatically.

Path Parameters

device_id
string
required

Device ID

stream_path
string

Stream path

Query Parameters

session_id
string
required

Session ID (UUID)

Response

OK

init_bytes_b64
string

InitBytesB64 is the base64-encoded ftyp+moov prefix from segment 0. The client appends this to a SourceBuffer before queueing media segments.

mime_type
string

MimeType is the full codecs string (e.g. video/mp4; codecs="avc1.640029").

session_first_ntp_ns
integer

SessionFirstNtpNs / SessionLastNtpNs are the session's NTP wall-clock bounds in nanoseconds, used by the UI to set playback slider extents.

session_last_ntp_ns
integer
timescale
integer

Timescale is the video track's media timescale (units per second).
