2. In the left navigation pane, click Domain Names.

3. Find the streaming domain that you want to manage and click Domain Settings in the Actions column.

SRT stream ingest and playback

SRT stream ingest

After you enable SRT, you can obtain an SRT ingest URL from the URL Generators in the console or by concatenating URL components.

SRT ingest URLs use the following formats:

• Format 1 (Recommended)

  srt://{domain}:1105?streamid=#!::h={domain},r=/{AppName}/{StreamName}?auth_key={access token},m=publish (Recommended)

• Format 2

  srt://{domain}:1105?streamid=push://{domain}/{AppName}/{StreamName}?auth_key={access token}

Custom parameter encoding rules

When the SRT ingest URL contains custom parameters, you must URL-encode the special characters to avoid parsing conflicts. Example:

srt://{domain}:1105?streamid=#!::h={domain},r=/{AppName}/{StreamName}?auth_key%3D1807696811-21613-0fa3597df7f228fbfae37020de3782b70%26sprio%3D6,m=publish

SRT playback

When the SRT protocol is used for stream ingest, the supported playback protocols include RTMP, FLV, HLS, and RTS. SRT playback is currently not publicly available. To use this feature, contact your account manager or submit a ticket.

SRT playback URLs support two formats:

• srt://{domain}:1105?streamid=#!::h={domain},r=/{AppName}/{StreamName}?auth_key={access token},m=request

• srt://{domain}:1105?streamid=pull://{domain}/{AppName}/{StreamName}?auth_key={access token}
