VLC doesn't play some videos from samba share using version 3.0.8. Downgrading to 3.0.7 works.
On Fedora KDE 30 system with kernel 5.2.17-200.fc30.x86_64, VLC stopped playing some videos from network shares (samba), after a package upgrade to vlc package 3.0.8-1.fc30. Most videos were bluray rips 5GB+, but I was able to confirm that it was able to play smaller videos. Earlier versions worked fine before the update. Seems like something related to the "seek" function vlc does when first opening a video. I downgraded to to 3.0.7-0.1.fc30 and the same videos were played successfully.
Only the following was written to the log:
-- logger module started --
main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
smb error: read failed (Software caused connection abort)
mkv error: cannot find any cluster or chapter, damaged file ?
smb error: read failed (Software caused connection abort)
mjpeg error: cannot peek
-- logger module stopped --
KDE/Qt stuff: plasmashell 5.15.5 Qt: 5.12.4 KDE Frameworks: 5.59.0 kf5-config: 1.0
This behavior parallels the one described in https://trac.videolan.org/vlc/ticket/22768 that was closed a couple of weeks ago. Seems like this is related to vlc since previous version works fine and I haven't changed anything pertaining my system.
