Stremio crashing when using Cloudflare proxy about stremio-gdrive HOT 14 CLOSED

Hmm, are you sure the credentials line is intact? You have to paste the code below it. Like:

var credentials = {blah blah};

addEventListener.... etc

from stremio-gdrive.

that was the issue, it's working now😂
I'll test a few movies and report back

from stremio-gdrive.

I should be the one thanking you for taking out the time to fix these issues, so thank you 😊

This will force stremio to use the stremio server running in the bg instead of directly playing the link.

I forgot to mention that when Stremio crashes and I quickly switch back to it I can see that its server is offline, so I'm confident in fix 2 as well !

Looking forward to test them both lol

from stremio-gdrive.

Well this is it, fix 2, if it doesn't work we have run out of options.... Hopefully it does work lol

from stremio-gdrive.

btw, should I revert back to the old cf_proxy.js script before testing fix 2?

Nah, stick to the new one.

Guess what, @ssnjr2002
The problem is finally fixed! No more crashes.
Finally lol
Thank you so much 🤩

So after some poking around I still haven't figured out what exactly is the problem. I have made some changes to cf_proxy.js and I want you to test it (code below). Go to cf workers -> your proxy worker -> quick edit -> select everything below the first line (var credentials line) -> paste the code below -> hit save and deploy.

I'll try asap and report back, thanks 👍🏼

Whenever I play anything, it says "Oops, Player Error. Stremio encountered an error with this media." The worker is alive (200 Online!)

Sadly, Stremio still crashes. ( I tried all HW modes again ).
Looks like this is an issue with Stremio then, not the addon... Thankfully, everything works fine without a proxy.

from stremio-gdrive.

Ah, thanks for confirming that doesn't solve the issue. This means the proxy code is fine. I have two more possible fixes. I will be pushing a commit later for the heroku side of things. You can test that out and report back whenever you have got the time.

Once again thank you for bringing these issues to light. This bug has been annoying me for a while and I always thought it was the app's issue.

Here is the possible problem and fixes if you are interested in reading it: 😉

Fix 1: In the stremio addon documentation here, in the notWebReady flag, it's said that non mp4 urls needs to have notWebReady set to true. For the non proxy version I did this but for the proxy version I did not. So this might be the problem.

Fix 2: If that doesn't work I will add proxyHeaders to make the behaviourHints exactly like how it is for the non proxy version. This will force stremio to use the stremio server running in the bg instead of directly playing the link. Non proxy version pipes the stream through the stremio server and that might be why the it works without crashing but the proxy version struggles since its directly streamed by the player instead of being piped through the stremio server. As to why the player might not be able to play the stream directly, without crashing, I am not sure. Maybe its a bug in the app.

I am more confident in fix 2 since this is how the non proxy version works but for the sake of pinpointing the issue we have to test fix 1 and then fix 2.

I tried fix 1, it worked well for ~30 minutes, but it crashed after that.

Hopefully lol
