Comic Library - Downloading .cbr/.cbz files often downloads as a .epub

[Nebarik 7]

As per title. I feel like Emby is doing some unnecessary file renaming when downloading comics. 

Emby Server Docker version 4.6.4.0
Accessing via Chrome for Mac, For Android, and the Android App. 

Depending on the browser/app it gives slightly different results. sometimes it works fine and downloads the .cbr/.cbz file with the correct file name. "filename.cbr"

But a lot of the time it downloads it as "filename.cbr.epub" or "filename.epub", or in 1 weird case in chrome it completely renamed it as "download.epub". I haven't worked out what causes each occurance yet, but it's so common its more likely to rename it than not.

Any chance this bug could be looked into so Emby just downloads the file with the existing file name. Thanks,

Hi there, can you please attach the emby server log from an example? Thanks .

Original file name is "Animosity (2016) - 01.cbr"
Android Chrome logs. Clicked download and it came out as "Animosity (2016) - 01.cbr.epub"
https://pastebin.pl/view/a7713d53

Android app logs. Set download location to External > Downloads folder. File came out as "Animosity__2016__-_01.cbr"
https://pastebin.pl/view/0c1c7813

Original file name is "約束のネバーランド (2016) - 01.cbr" 
(In hindsight I'm guessing the non-english characters are the problem here, also happens on Android chrome)
Mac Chrome logs. Clicked download and it came out as filename "Download.epub"
https://pastebin.pl/view/4cdc5fb8

While testing, I couldnt get it to replicate with CBZ file types on either Mac or Android Chromes. They seem immune to the renaming issue. 
The Android app still renames the spaces and symbols, but keeps it as a .cbz. 

Hopefully the logs help, they dont appear to immediately give the obvious answer to me. 

Thanks,

Hi, this part of it should be resolved in Emby for Android 3.2.24+.

The rest of it I think is caused by the browser, probably due to the Content-Type http response header we're sending. For cbr files, the content-type we're sending is application/epub+zip

[Luke 42077]

I guess we should probably change that to application/x-cbr

Thanks, I look forward to the new updates

Can confirm the new Android app (3.2.26) has resolved the renaming issues (screenshot attached)

Hi, there's nothing in the Android app for this. The change will actually be in the server.

For the Chrome based downloading yeah, awaiting a update for that fix. 

But like you said, the Android app update fixes the underscore renaming:

I was just posting to show that it is indeed fixed in the app now.

Strictly speaking, the MIME type for CBR files is application/vnd.comicbook-rar, and for CBZ files it's application/vnd.comicbook+zip.
