Player and chat issues

[rapyyy]

Hello everyone :),

I recently installed the Ganymede stack and it's working perfectly. However, I have a small issue with the player. Indeed, the video (VOD) takes several minutes to start and afterwards it is impossible to advance or rewind. If I try to fast forward or rewind, the video always goes back to the beginning. Similarly, the chat never appears.

However, the VOD and the chat are properly recorded and I can watch them through the files for example.

The problem is widespread but if you have any ideas, I'm open to them :)

Thank you !

Couple of questions:

• Is this a remote instance (being hosted on a remote server) or local?
• What browser are you using?
• Can you paste the "Video FFProbe" output here?
  • Can be retrieved by opening the video menu and clicking "Info"
  •

Hey Zibbp,

Thanks for your answer.

• Ganymede is hosted on my remote server.
• I use Chrome and tried with Firefox and in incognito session.
• Video FFProbe output :

Loading large mp4 files over a remote connection (non lan network) can be slow. MP4 doesn't have any chunking and often requires downloading a large portion of it to start playing. There's a setting in Admin > Settings called "Convert to HLS". This will convert downloaded videos to HLS which basically is a fragmented MP4 that loads a lot quicker over slow remote connections. Can you enable that and try archiving another VOD? It will not retroactively apply, you need to archive something new. Once it's archived check if it loads any faster.

Hello ! Sorry for the delay.

In fact, with HLS activated, all is alright now. The VODs and chat are loaded and so much faster !

Sorry for bothering you with this and thank you very much for the details.

Excellent work again :)
