I found this bug in too many versions, and the videos from No. 1 to No. 15 played normally.
If there is an ungrouped video after a group, the error will appear, similar to the 16th video.

Sorry, my description is not very good, but I have tried my best. Thx

This is very weird.

If you ungroup in the menu, can you play that file correctly?

Hi,

Just to confirm, you're grouping by name and not by folders right?
Ideally, could you dump your database and send it to us? Go to settings -> advanced -> Dump media database, you'll find a vlc_media.db file at the root of your main storage. If you can send send it to xxx@videolan.org that would be a great help

Thanks!

Yes, if I ungroup video, all is ok.

HI,

ⅰ ⅱ ⅲ ⅳ ⅴ…just for group number

I had do something:
1. Clean VLC app's storage, the error is also here
2. ungroup ⅶ Expanse S04E10 Cibola Burn NTG, but the two video are behind the Knives.Out.利刃出鞘.2019.中英字幕.WEBrip.1080p-CS.mp4, and the playback results is error

3. regroup the The.Expanse.S04E10.Cibola.Burn.1080p.AMZN.WEB-DL.DDP5.1.H.264-NTG.mkv and The.Expanse.S04E10.Cibola.Burn.1080p.AMZN.WEB-DL.DDP5.1.H.264-NTG.eng&chi.mkv, the two video is ok.

My thoughts on the cause of this bug:
After group video by name
a) Video with the same name in the group, search the sequential position of the video in the group during playback.
b) Videos that do not belong to the same name group, that is, there is only one video in a group, during playback, according to the grouping position, search for the sequential position of the video in all videos, for example, if the video is in the sixth group, then search for the sixth in all videos Videos, this is wrong.

My thoughts on solving the bug:
After group video by name, the Video with the same name in the group are behind Videos that are not group as the same name group (one video in one group).
Just like in Windows and Linux systems, the folders are in front of the files, and then sorted by name.
the result as:
ⅰ 1. [AJZero&Mabors Sub&MGRT]Kokoro ga sakebitagatterunda[GB&BIG5](BDrip_1080_HEVC_yuv420p10_FLAC).mkv

Thanks.

Another thoughts on solving the bug:
Make one video in one group as similar as more same name videos in one group, then sort group by name. User should choose the group before choose video.
make it like group a, group b, group c, group d, group e
not group a, video A, group b, video B, video C.

I can't reproduce with the same file names on my phone, I reached out privately with the OP to gather more info/logs

Maybe it has something to do with the brackets in filenames ?
