Movies thumbnails not working on SMB shares

Postby Cuisto » 28 Nov 2020 00:14

Hello,

I noticed a problem with thumbnail when accessing movies
I access smb share and play movies without problems, but mp4 thumbnails aren't shown.
However, we can generate these thumbnail but it's very convenient :
1. access mp4 file on smb share : no thumbnail
2. copy mp4 file on android device
3. access mp4 file on android device ( with browse or video menu) => thumbnail automatically created in Android/data/org.videolan.vlc/files/medialib/filename.jpg
4. delete mp4 file on android device (thumbnail in medialib directory is still present)
5. access mp4 file on smb share : thumbnail present

The process in VLC to create thumbnail works great, but not on smb share.
The results fot thumbnails are the same if i upload a picture in mp4 file with mp3tag application on Windows. But VLC correctly reads picture in mp4 file if present.

Is it possible to correct thumbnailing behaviour ?

I tested every VLC releases since 2019, actually 3.3.3 Beta 3 : it never worked on smb shares
Tested on Android 6, 9 and 10 Xiamoi smartphones and nvidia shield k1 devices

Thanks for this great application

This is an intended behavior.

The thumbnail generation is a quite heavy process that is done, for local file, when scanning your folders. It's not activated for files that are not scanned (and network files cannot be scanned).

In a future update (3.3.3), you will get more info on unscanned files if you have already played it though.
