Introducing PrismCast: Browser-based Live TV Capture for Channels DVR and Plex

It's currently a fork that is patched. I'm vibe coding it so someone who actually knows what they are doing can make it better.

I will try and get it working soon . I need to figure out how often it needs to occur.

ESPN is almost perfect. It loads right when it dies after an event but it does a weird load that makes it load again due to the strict url being resolved in a weird way. I have an idea to do a baton handoff from a guide data scrape that will make it very smooth. That's how peacock works

Got a question on FruitDeepLinks and Prismcast using ESPN.
I have got it setup, it looks good. The autoselect doesn't work, but I found one that works especially for ESPN which is Keyboard Dynamic.
The guide is working properly, but when I click on a game, it will play for a good 10 to 20 seconds, then it stops playing. I checked on Prismcast using VNC and it opens up the page perfectly and it is playing in the browser, but it just won't play on TV or even the channelsdvr web app. I have tried every single of the profile options and found only 2 that seem to work a little, but my issue is that it only plays for a few seconds, while within prismcasts browser it looks like it's playing just fine.

OK so I got a weird one here. Currently the PBS Feeds docker is down waiting for a cert update, so I switched back to Prism to get my local PBS. But for some reason now when the Chrome instance brings up www.pbs.org/livestream, I only get 480p and it won't switch to HD. However if I start a new Chrome instance on the same server, it starts and runs as 720p?!? This just happened recently.

Anyone else seeing this?

All of a sudden I am receiving closed captions from Prismcast. I cannot turn them off from within Channels. Any ideas?

When you authenticate that channel, turn the closed captions off in that tab. Hopefully, that should fix it.

That seems to have worked. Thank you.

Is there any fix for the constant tab replacements / Detected 10 consecutive undersized segments?
This is making Prismcast as a source unwatchable.
Using Prismcast in Docker on Windows. Chrome is Version 149.0.7827.201.

What are the specs on your Windows PC?

Its a Beelink Mini PC

  • Model: Beelink EQI12
  • CPU: Intel i3-1220P
  • Memory: 16GB DDR4

This problem has only just started for me. Sometimes play will be problem-free for hours; other times it will tab refresh every 3-4 minutes.

Would changing to a native installation help?
