}- (refs.) SRT API Socket Options
- (refs.) SRT Access Control (Stream ID) Guidelines
- in case of ffmpeg, streamid is specified by -srt_streamid option
- r : resource name identifies the name of the resource
- m : mode expected for this connection
- request (default) : the caller wants to receive the stream
- publish : the caller wants to send the stream data
- at : specifies requested position of recorded data
- ISO string : specifies the date and time to be requested in ISO8601 syntax (ex.:"20230317T123000+0900")
- now-{{sec}} : specifies the time seconds before the current time
- now (default) : specifies live stream instead of recorded data
- gap : specifies the action to be taken when the stream reaches a gap in the recorded data.
- skip (default) : skip to the next recorded data without waiting
- wait : wait for a time corresponding to the gap before starting the next recorded data
- break : break the stream when a gap appears
- speed : specifies playback speed (synonym: x)
- 1 (default) : normal play speed
