Initial replay functionality

[gabek]

This is the core internal functionality to support stream replays and clips with Owncast. There is no UI, and it is disabled by default. Use --enableReplayFeatures to enable the feature flag.

Also enables S3 path prefix, to support a custom path within an object storage bucket.

This is not yet useful to people, as it's just a bunch of APIs (that do function), but is the first step to have this functionality.

There is also no cleanup logic. When enabled all video is saved on disk forever.

Details

• /api/replays returns a list of all the streams that are replayable.

URLs are generated as so:

• /replay/streamId for master playlists.
• /replay/streamId/configurationId for media playlists.

Testing in progress stream

1. Start a live stream
2. Visit http://localhost:8080/api/replays
3. Note the "manifest " path.
4. Put the manifest url in your livestreaming video player of choice.
5. Play it. It will be treated as an updating (event) style stream.

Testing completed streams

1. Stop the live stream.
2. Visit http://localhost:8080/api/replays
3. Notice this stream is no longer in progress.
4. Put the manifest url in your livestreaming video player of choice.
5. Play it. It will be treated as a static (VOD) stream and will not update.

Clips

• Follow the instructions above to have a replay of a stream.
• Get the streamId you want to create a clip from.
• Determine the start and end points, in seconds, for this clip, relative to the beginning of the stream.
• Use the clip create API to create the clip as a JSON payload to /api/clip with streamId, clipTitle, relativeStartTimeSeconds and relativeEndTimeSeconds

http http://localhost:8080/api/clip streamId="oYk3sL6Vg" clipTitle="Test clip 5" relativeStartTimeSeconds:=10 relativeEndTimeSeconds:=17

• List all clips with the clips api /api/clips.
  

• Fetch a single clip with /clip/{clipId}.

• It will return back a HLS master playlist that is playable.
