html5-player | player provides a unified js interface supports html5 video | Video Utils library

I'm currently trying to implement a video player using Media Source Extensions. Currently just a very simple proof of concept, following a tutorial I found here.

I'm trying to stream audio file to Angular application where is html5 audio element and src set to my api end point (example. /audio/234). My backend is implemented with .NET Core 2.0. I have implemented already this kind of streaming: .NET Core| MVC pass audio file to html5 player. Enable seeking

Seek works if I don't seek to end of file immediately when audio starts playing. I use audio element's autoplay attribute to start playing immediately audio element has enough data. So in my situation audio element has not yet all the data when I seek so it make new GET to my API. In that situation in my backend log there is this Exception:

fail: Microsoft.AspNetCore.Server.Kestrel[13] [1] Connection id "0HL9V370HAF39", Request id "0HL9V370HAF39:00000001": An unhandled exception was thrown by the application. [1] System.InvalidOperationException: Response Content-Length mismatch: too few bytes written (0 of 6126919).

Here is my audio controller GET method.
