Streams sometime get "stuck" on a segment

[miyakoj]

Description

We're using Video.js and Video.js HLS to create a video wall with a page usually containing 4 or more players. All of our streams come from DVRs external to the network and VLC is used on our server for transcoding. A Node.js script restarts the transcoding process for a stream when there's a problem (which restarts the segment numbering over at 1), but that sometimes causes the player to get stuck in a loop trying to download the last segment it was downloading when the process restarted, which keeps 404ing. Reload source on error doesn't trigger. I added a double click handler on the player to trigger an error to force it to reload, but that doesn't help.

Sorry, I can't include a reduced test case because the streams are private.

Sources

Can't provide.

Steps to reproduce

Explain in detail the exact steps necessary to reproduce the issue.

1. Load multiple players with working live streams.
2. Temporarily kill the web server process.

Results

Sometimes the stream doesn't resume, the current segment 404s repeatedly instead.

Expected

The stream will resume playing when the web server comes back up.

Error output

GET XHR http://[...]/video/3/fileSequence000085.ts [HTTP/1.1 404 Not Found 54ms]

We've recently made a fix for live stream disconnects, is this still an issue for you in the latest version of video.js? Video.js 7 now includes HLS playback by default and includes https://github.com/videojs/http-streaming which is the next version of this project.

We decided to create a native desktop solution (using C# and Vlc.DotNet) because both Chrome and Firefox continuously crashed when playing multiple videos simultaneously. Thank you for following up anyway.
