[Issue]: Request to /Videos gives 200 OK but empty response on IPTV playback attempt #10168

Please describe your bug

I am working on the LiveTV implementation in the Swiftfin client. I am running into some issues with playback from my IPTV source. In my configuration, I have some local HLS channels created by ErsatzTV, and some remote IPTV channels from a service I am subscribed to. They are combined with Steve and exposed to jellyfin via m3u.

I've found a scenario where playback attempts in Swiftfin with the VLCKit based player and the Force Direct Play flag turned ON results in failure to play any video when I select one of my IPTV channels. ErsatzTV channels seem to work just fine, though.

When I dug into it, I found that when the Swiftfin client sends a request to /Video/{id}/stream..., in the ErsatzTV case where it works, I get a response with a content type of application/x-mpegurl, and the body looks like the start of an HLS stream.

But in the case where playback fails, with my IPTV channels, the request to /Video/{id}/stream...results in a 200 OK, yet the content type says text/html; charset=utf-8, but the body is totally empty. Content-Length is 0.

It seems like something went wrong, and playback can't start for that channel. Yet the response said 200 OK.

This same IPTV channel plays fine in the Jellyfin browser interface. Or I can take the direct URL and open it with VLC.
