Description Vladimir Yerilov 2020-05-16 16:04:05 UTC

SUMMARY
Since KDE apps 20.04 streaming videos (mp3 music is fine though) from samba shares is impossible. Here's what VLC throws at me when I try to open a video file:
```
Your input can't be opened:
VLC is unable to open the MRL 'smb://10.0.0.1/Video (at ASMT)/YI000201.MP4'. Check the log for details.
```
Here is what's going on in terminal where Dolphin is launched from:
```
QFSFileEngine::open: No file name specified
QFSFileEngine::open: No file name specified
QFSFileEngine::open: No file name specified
QFSFileEngine::open: No file name specified
QFSFileEngine::open: No file name specified
VLC media player 3.0.10 Vetinari (revision 3.0.10-0-g7f145afa84)
[000055e82296a620] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
QFSFileEngine::open: No file name specified
[00007f4800001620] smb stream error: open failed for '10.0.0.1/Video (at ASMT)/YI000201.MP4' (Invalid argument)
QFileSystemWatcher::removePaths: list is empty
QFileSystemWatcher::removePaths: list is empty
QObject::~QObject: Timers cannot be stopped from another thread
```

STEPS TO REPRODUCE
1. Open SMB v1 or v2 only share
2. Click on video to open it in your media player
3. Observe the fail

OBSERVED RESULT
Described above.

EXPECTED RESULT
I wish it could be at least as it was before the update to 20.04 apps.

SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Manjaro Linux 20.0
(available in About System)
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 5.70.0
Qt Version: 15.4.2

ADDITIONAL INFORMATION
No changes in smb.conf were done, it's still the same as it was before updates for KDE apps and frameworks. Tried with Dolphin 20.07.70, the result is the same.

Comment 1 Vladimir Yerilov 2020-05-16 16:11:58 UTC

Sorry I'm not that into KDE development to recognize what to blame for this bug -- Dolphin or KIO. I just know I should report it (should have reported it as soon as I faced it almost a month ago).

Fun fact: streaming of the video in Dolphin's preview pane works!

Comment 2 Nate Graham 2020-05-16 17:42:42 UTC

What happens if you open VLC directly with that URL? e.g. `vlc 'smb://10.0.0.1/Video (at ASMT)/YI000201.MP4'`?

Do you have the kio-fuse package installed?

Comment 3 Patrick Silva 2020-05-16 23:20:11 UTC

I can confrm an error message with VLC installed via flatpak/flathub.
VLC from ubuntu bionic repos downloads the video and plays it.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.18.80
KDE Frameworks Version: 5.71.0
Qt Version: 5.14.2

Hi Nate. Here is the output:

Comment 5 Harald Sitter 2020-05-18 10:56:03 UTC

Seems like the VLC build itself is broken seeing as it cannot stream from smb at all.

Comment 6 Vladimir Yerilov 2020-05-18 11:43:16 UTC

At first I thought it might be a VLC issue, but SMPlayer cannot play too:
```

```

Comment 7 Harald Sitter 2020-05-18 11:56:13 UTC

My point is: it's not a dolphin issue if vlc fails to play the smb URL without dolphin involvement. It may however still be underneath VLC... e.g. if both players use libsmbclient then libsmbclient may well be broken. I don't know what they use under the hood though :)

Yeah, me too. I'm just puzzled by this happened only right after the update to Dolphin 20.04, I had read Nate's blog about Dolphin's samba-related improvements and decided to give it a try. First it made me laugh but soon it got forgotten since I use NFS as a main way to access my network stuff.

Comment 10 Harald Sitter 2020-06-02 08:25:40 UTC

Best take this to vlc and/or the samba bug tracker. Seeing as streaming isn't working when dolphin isn't involved either this isn't a problem in Dolphin (there still may be one but currently there is no evidence of that).

Comment 11 Vladimir Yerilov 2020-06-02 10:32:01 UTC

Oops, totally forgot about this issue.
Yes, it is upstream related, either vlc and/or smplayer or smb(client?).
I tested in Ubuntu Gnome, errors are the same, but no problem with Ububntu's default video player (Totem?).
