Error preparing player items about findroid

[Derkades]

Yes, it has been fixed. Thanks!

[jarnedemeulemeester]

Hmm interesting...

Is there any way you could give me access to your Jellyfin instance? That way I can test it and figure out what the problem is.
If you can, just email me the url and login credentials. ([email protected])
Or Reddit dm whatever you prefer. (JDTechn0)

If not then no problem, but I really have no idea what the issue could be.
Maybe there is a episode with no mediasource or something.
Either way, it's an issue with the app and I would love to fix it :)

I have the same issue with a particular video, would it help if I sent the video file?

I sent you the url and login credentials to you. Thanks for helping me.

[lauw0129]

Thanks for updating the app. But I just tried and it's also showing the same error message. Do you think it's because of H. 265?

[jarnedemeulemeester]

@lauw0129 Hmm on two devices I tested the video player opened (didn't play because of codec issue but that's a separate issue).
I tested with the first episode of Your Lie in April with a Pixel 1 & 3.

@lauw0129 @Derkades In v0.1.1 there should be a new button next to the error message called "View details" (or "@string/view_details" because I made an oopsie). If you click on it a dialog should open with a detailed error message which you can share here :)

[lauw0129]

But there's no any details at that button

[jarnedemeulemeester]

Looks like an IndexOutOfBoundsException. I will do some more testing and keep you updated.

[lauw0129]

Ok thank you

[jarnedemeulemeester]

@lauw0129 I am really struggling to find the cause of the problem.
I tested on many different devices, including an emulator with Android 7.0 (minimum supported by the app) and all worked.

What device are you using?

• Device name:
• Android version:

Can you also try using the user you provided me? To do this you have to remove your current server and add it again.
Settings -> Manage servers -> Long press the server -> Remove
Then add your server again but with the user 'jarne' you gave me. Maybe some configuration is different between the user you were using and the one you gave me.

I really want to solve this issue and I know on which line of code the error happens but I don't know why.

Let me know if my user works or not and what device you are using.
I appreciate the effort and sorry for the trouble!

[lauw0129]

I just tried to login your account (jarne) in my server and it's "can be played". It means I can click in it and see the player screen. But it's didn't show up anything. Just black screen and the it won't load. By the way thanks for your app. It's cool.

https://youtu.be/CQy5lLt5-Uk
This is what's happening

PS: Because of the screen recorder problem it's vertical at the player screen. But it's horizontal in my view.

[lauw0129]

Could you see the video when you tried?
The following is mine
Device name: Xiaomi Mi 10T Pro 5G
Android version: 11 RKQ1.200826.002

[lauw0129]

Screenrecorder-2021-08-23-23-15-12-194.mp4

It's from my friend's

[jarnedemeulemeester]

Yes I see. When I try on my devices I also just see a black screen.
It's probably because the media uses H.264 High 10 profile which can't be played on some devices.
This is something I can't fix immediately, I would have to implement a different player like libVLC or libMPV.
This is also a separate issue.

Now back to the "Error preparing player items" error.
Could you please tell me what is different between the two accounts? Maybe some setting?
It's strange that my account doesn't show this error but yours does.

[lauw0129]

There don't have any error in the new account. It just showed black screen. It could be the the media problem. But can it be solved by transcoding? I think transcode in the Findroid app may help to solve this problem

[Derkades]

Do you know where the indexoutofboundsexception occurs specifically (which array lookup)? Does it print the stacktrace to a log somewhere? I've never tried accessing android logs but if it's useful to you I'll look into it.

[lauw0129]

I am not good at programming or something like those. So I also can't find where is the log.

[jarnedemeulemeester]

@Derkades This line:

findroid/app/src/main/java/dev/jdtech/jellyfin/viewmodels/EpisodeBottomSheetViewModel.kt

Line 84 in e694f63

playerItems.add(PlayerItem(episode.id, mediaSources[0].id!!))

It gets the first mediaSource from the mediaItem and it does this for all next episodes in the season. This to make a playlist for ExoPlayer to play all episodes after each other. This code could be much improved, and it will be!

Now I think I know why the problem occurs, @Derkades do you have missing episodes enabled?
Episodes like this in the web ui:

If this is the case then I will be fixing this tomorrow :)

[Derkades]

I do have missing episodes enabled but this specific episode only has one entry and it is not missing. Some other episodes in the same season do have duplicates (one of which is missing)

[jarnedemeulemeester]

@Derkades could you send me some screenshots of the season with the episodes in the web interface? I don't completely understand what you mean sorry

[Derkades]

Sure thing:

[jarnedemeulemeester]

Hmm okay I see. Any missing episodes after 14?

[Derkades]

No, episodes 15-18 all present

[jarnedemeulemeester]

I have added a fix for missing episodes. If there is a missing episode, it will just skip that one.
This should be in the next update.

But I'm not sure if that will have fixed your issue @Derkades
Any way you can give me temporary access to your Jellyfin server to test it out? But I would understand if you wouldn't want to do that.

[Derkades]

I've sent an email with login credentials

[jarnedemeulemeester]

Thanks a lot, this issue should now be fixed!

The fix will be included in v0.1.2.
If you update to that version and still encounter problems, feel free to open a new issue :)
