So, the flow is following:
user registers pipeline-loaders via pipelineLoaderFactory storage, or via separate api for worker-based player (so it is opt-in operation)
user calls load with some payload includeing mimeType
player checks and finds match for loaded mimeType and pipeline-loader-factory
player creates pipeline-loader instace via found factory and injects core deps
player passes loadPlayload to the created loader instance
loader creates parser via registered factory and injects core deps
loader loads manifest/playlist
loader parses received data
loader creates pipeline via registered factories and passes core deps and parser instance and returns this instance back to the player.
so as you can see there is a layer of dependency injections
so, we should have a static members to register hls parser factory (not instance) in the hls-pipeline-loader (not pipeline itself)
anticipated follow-up question:
why do we need pipeline-loader? can’t we just create pipeline directly in the player?
because we want separate classes for live and vod pipelines and we don’t know ahead of time which one to create. We can understand it only once we load and parse playlist/manifest.

For clarification, do we want to expose the instance of the parser (this.parser_) from the hls-pipeline-loader via the service-locator or do we want to simply expose the factory? I refactored to expose registered factory, per the feedback above, however the rfc example indicates we would want to expose the current instance of the parser instead:
const hlsParser = serviceLocator.getHlsParser();
hlsParser.parse(playlist);
Description
getHlsParserfunctionality to the service locator.Specific Changes proposed
expose the full HLS parser through the a
getHlsParserfunction and add tests.Requirements Checklist
