Hello Shlomi
Thanks for your job

I can't send a file as an attachment (13 Mo)

here is a link to download it
https://framadrop.org/r/3wH6phtDRa#46c5qxN3H0kq1yJBUV9JOHYY76r8CPOHi1asvPRnRQM=

PS I'm gonna try to use the live DVD and download the VLC program from their site to test it and verify if it's a package problem or a VLC 3.0.6 problem

Sorry

it's no more possible to download a universal linux version of VLC from their site (to be installed in a local directory as it was possible some years ago)
They only offer links to rpms repositories for fedora or opensuse or to deb repos for debian and ubuntu

No other way to test the 3.0.6 version in Mageia

Need to try the last fedora Live DVD to verify if VLC 3.0.6 can read webm or matroska files with VP9 codec

This file plays fine on mga7 x64 with both /usr/bin/vlc and one installed from git master. It isnt ok in vlc on my fedora30 x64 laptop. mpv plays it fine everywhere. Please try updating the mga7 system.

Thanks for your quick answer

Well...
I don't want to install Mageia7 yet and can only use the Live DVD so it's not possible for me to update everything (no memory enough for 700 packages...)

Nevertheless I installed mpv which indeed can read correctly the problematic webm and matroska files 

I updated VLC (and its plugins) from core update repo 
It's not better neither for VLC nor Dragon player
updating ffmeg gstreamer mplayer doesn't change anything

and then I used the tainted update repo to update the whole stuff
it's always so bad

I tried also to change from OpenGL 2.0 to OpenGL 3.0 or Xrender but nothing better !


If it is OK on your installed mga7 the problem doesn't come from vlc itself 
(that woukd be surprising because it's a true Swiss Army Knife)

Perhaps something is missing on the Live DVD, but I can't imagine what

Perhaps something wrong about interaction between Plasma and VLC
(I'm gonna download and try the Gnome Live DVD to see if the same problem occurs)

(The mageia6.1 plasma Live DVD was OK out of the box !)

What is surprising too is that the problem appears with Fedora 30 !

Hi again Shlomi

So
I used the Gnome Beta2 Live DVD 64 bits

I updated VLC and installed mpv

The problematic webm and matroska files are always badly displayed by VLC

But it is OK with Totem and mpv ...

Is there an unknown missing dependancy for VLC in both of these Live DVDs since you can use VLC for them on your installed MGA7 system, but I can't with the Live DVDs

Same problem with With Mageia 7 Plasma RC Live DVD 

VLC (3.0.6-11) can't fluently read .mkv or .webm files when the video codec is VP9 
(but it could with Mageia 6.1)

NB : I installed the version and all the plugins from the tainted repo...

NB bis : Now Dragon player can read the problematic files without any problem


I modified the priority to high
and severity to major 
because it's a real regression since last version provided by Mageia

(perhaps a build option... this seems to be related to the fact that vpx was disabled and BuildRequire libvpx suppressed on 15th october 2018 for VLC 3.0.4 non building with vpx 1.7)

Perhaps version 3.0.6 of VLC may now build with last libvpx 1.8.0 ?
or at least with libvpx 1.7.0

Severity: normal => major
Priority: Normal => High

With this file - https://www.shlomifish.org/Files/files/video/KPatience%20Solving%20a%20FreeCell%20Deal%20Automatically-K-AU6yiV0FM.webm - downloaded using youtube-dl from https://www.youtube.com/watch?v=K-AU6yiV0FM&feature=youtu.be , then vlc-3.0.6-11.mga7.tainted plays it without a problem on mga7 x64.

1. Can you play that file?

2. Can you share an offending sample video file? The original link is not working.

Hi Shlomi

Thanks for your quick answer

I launched the live plasma DVD RC (with proprietary drivers for Nvidia graphic card)

I installed vlc tainted and all its plugins
I installed too :
- mpv
- mplayer
- xplayer
- totem
- xine

I can read the video from your address directly inside Firefox : OK

Once downloaded...
I can read it fluently with
- mpv
- dragonplayer
- Totem
- mplayer
- xplayer

But 
with xine it crashes after 5 seconds
with VLC I get garbage pixellised not fluent (staying stuck on a frame for 1 second)


For my own files the less big one is quite heavy (74 MB) so Framasoft keeps it only for a week (reason why the link doesn't work anymore)
I upload it on this address :
https://framadrop.org/r/ja4KREle7E#K1wM4pPqdCIAUPQWNbe5YLQb5gPRdb81r3wIAIetJ8Y= 
(hope you'll enjoy it : this man is the best doublebass player I know !)

NB : Everything is OK on my up to date Mageia6 : VLC even offers a zoom slider
inside the display window

I'm gonna try the Live DVD without proprietary drivers

Well
I just tried the Live DVD with nouveau instead of nvidia drivers

The problem is still the same : 
OK with mpv, dragonplayer, totem, mplayer, xplayer

Garbage with VLC, crash with xine ... for my files or yours

If you can play it on your computer (I think you have Mageia7 installed) perhaps there's a rpm installed on yours that is not explicitely required by VLC and missing on the live DVD  (a missing Require in the spec ?)



PS I discovered that xine (that I never use normally) crashes too on Mageia6 for those files. Nevermind it's useless when we have VLC (a real Swiss army knife)

Guess what rpm may I try to add blindly (without knowing the required) when I use the Live DVD ?

(In reply to Philippe Didier from comment #14)

I've now tried the plasma5 mga7 rc livedvd in a vbox vm, and vlc there plays both files fine. :(.

(In reply to Shlomi Fish from comment #15)

> I've now tried the plasma5 mga7 rc livedvd in a vbox vm, and vlc there plays

I can't imagine where I may dig to understand this bug
for me : same computer for installed Magia6 or for the liveDVD

nvidia driver or nouveau driver lead both of them  to the same bug on the LiveDVD
but not on Mageia6

VLC, which usually can read anything, is the one that can't read VP9 videos besides mpv mplayer totem and dragonplayer which can on my computer with Mageia7

But you can use the LiveDVD without this bug


The problem is on my side certainly because of an incompatibility between VLC and my GPU

I will verify the default configuration of VLC on the LiveDVD and change it

The option for hardware decoding is "automatic" in Mageia6 
perhaps I'll have to unactive it and see if it's better

No : I installed ALL vlc plugins from the tainted repo (with their dependancies) and lib64matroska6 is on the LiveDVD

VLC can read every kind of multimedia I have tested : avi, flv, mp4, ts, mpg, TS.VOB, wmv, asf,  whatever the video codec is used

I have only this problem with webm or mkv files when the video codec is VP9
(but it's Ok for mkv files when the video codec is H264)

I wil try without installing vlc-plugin-openGL

Last try

Plasma Live DVD
without proprietary drivers
I didn't add tainted repo 
So VLC is out of the box with the plugins from the DVD

I didn't add vlc-plugin-opengl
 
I use the file provided by Shlomi :
https://www.shlomifish.org/Files/files/video/Dorantes%20&%20Garcia-Fons%20rondenas.webm
that I previously downloaded on an external HDD

Garbage with VLC 
but DragonPayer is OK

NB I can read fluently the webm file from this address with Firefox

I will attach messages files from Mageia7
and from Mageia6 about the same video file

I'm knocking my head on the desk : I can't understand where the bug comes from!!!

Is it a regression of VLC that cannot work anymore on the same computer ?
Is it a problem with mageia7 ?



Should I try to compile the last VLC 3.0.6-11 (provided on Mageia7) from its SRPM on my computer running Mageia6 to see if the bug appears ?

Or is there a possibility to use the BS which is used to build updates for Mageia6 so that you build it and provide it temporarly as an update on a specific testing repo

weird, i hope when the new version is ready bug#24940 also this issue gone for you

Hi Shlomi

I think that the better way to determine if it is a problem caused by the last version of VLC (and not a problem from Mageia7) would be to provide VLC 3.0.6-11  in the update-testing repos for Mageia6, core and tainted, (without  proposing it to the QA team..)  or in your own repo (same as the webm file you provided)

I would download it and test it on my computer with Mageia6 on which VLC version 3.0.2 is OK


If it goes wrong I would easily downgrade from version 3.0.6 to version 3.0.2

What do you think of this ?

we should update vlc in mageia 6 to 3.0.7 anyhow. The .webm file was on a plain https service - not really a mageia repo.

Thanks, I will try VLC 3.0.7 as soon as it is in tainted updates testing repo
for Mageia6

Beside that, to test VLC I used the media that you downloaded from the http address and that you provided on your personal site in comment 9 (knowing it's not a mageia repo) 

I tried to read it directly from the original address with Firefox and got no problem

comparing the log files from Mageia7 and Mageia6
I found a difference that may explain that it works on Mageia 6 :

main debug: looking for opengl module matching "any": 2 candidates
main debug: resized to 1280x769
main debug: VoutDisplayEvent 'resize' 1280x769
glx debug: using GLX extension version 1.4
main debug: using opengl module "glx"
main debug: looking for glconv module matching "any": 3 candidates
main debug: no glconv modules matched
gl debug: PBO support enabled
main debug: using vout display module "gl"
main debug: A filter to adapt decoder VAOP to display I420 is needed

   But not on Mageia7 :
main debug: looking for vout display module matching "any": 10 candidates
main debug: VoutDisplayEvent 'resize' 1280x720
main debug: resized to 1280x720
main debug: VoutDisplayEvent 'resize' 1280x720
xcb debug: connected to X11.0 server
xcb debug: vendor : Mageia
xcb debug: version: 12004000
xcb debug: using screen 0x59c
xcb_x11 debug: using X11 visual ID 0x21
xcb_x11 debug: 24 bits depth

xcb_x11 debug: using X11 graphic context 04600001
main debug: using vout display module "xcb_x11"
main debug: A filter to adapt decoder VAOP to display RV32 is needed


So with Mageia6 VLC uses opengl
with Mageia7 VLC uses xcb_x11

Shlomi, would you try a build on update testing repo for Mageia6, (without proposing it to QA) so that I install it and see if it works on Mageia 6
to determine if it's a problem of these versions of VLC (3.0.6 and 3.0.7)
whatever version of Mageia I use

Or if it is a problem specific of VLC and Mageia 7

Hi Shlomi
To be sure it is not something specific to the use of a LiveDVD I tried 
Mageia6.1 Plasma LiveDVD

I could read without any problem 
https://www.shlomifish.org/Files/files/video/KPatience%20Solving%20a%20FreeCell%20Deal%20Automatically-K-AU6yiV0FM.webm

with the Live DVD out of the box (without installing anything else)
its version of VLC is 3.0.2 

I saw you tried to build VLC 3.0.7 for mageia 6 update-testing but it was rejected

Sorry I cannot try it with Mageia 6 to determine if it is a bug from VLC 3.0.6 or VLC 3.0.7 itself or a bug from its integration inside Mageia 7

hi, it is here: http://mirror.isoc.org.il/pub/mageia/distrib/6.1/x86_64/media/core/updates_testing/ .

Hi Shlomi
and thanks again for your work and celerity to answer

I installed vlc 3.0.7.1-1 from this core update-testing repo
(NB it doesn't exists in the tainted update-testing repo)

it works perfectly on my Mageia 6 up to date
so it may be proposed to QA for Mageia 6 (after having been built for the tainted repos)


But the conclusion opens to a more difficult problem :
 it's definitely not a simple bug of VLC itself  :(

It appears to certainly be a problem of integration of VLC inside Mageia 7

Where to dig ?

Hi Shlomi

I have dug a little
And I found little differences between the two spec files of VLC  3.0.7.1-1 :
The one of VLC for Mageia 6 update is not exactly the same as 
the one for Mageia 7

Besides the use of pkgconfig(*) instead of lib*-devel in the BR that has no impact indeed
and the addition of some new BR (such as fdkaac) that may do nothing for VP9 video
or the suppression of the kde build
or some patches suppressed or added that may have no impact



I saw that BR vpx was suppressed and build with vpx disabled in Mageia7
and BR aom added and build with aom enabled in Mageia

Could it be the reason why I can read a VP9 video with Mageia 6 and not With Mageia 7  using the same version of VLC in both of them

Sorry for the omission of the version number in this second line

I saw that BR vpx was suppressed and build with vpx disabled in Mageia7
and BR aom added and build with aom enabled in Mageia7

Hi Shlomi

I saw that VLC 3.0.7.1-1 is now avalailable for Mageia 6:
 in core-update-testing repo 
and in tainted-update-testing repo

But it hasn't been proposed for QA

Should it be proposed as an update request in an other bug report ?

Thanks

PS Beside this I'm waiting for the official Mageia7 Live DVD to test VLC with it
And then install Mageia 7 with the classical DVD and try to verify if there's a difference

Hi
I tried the last Live DVD 
It's always the same problem for the webm examples

NB the last and same version of VLC (3.0.7.1) in mageia6 update-testing repos works perfectly for these video files

It seems to be specific to the compilation of vlc for mageia 7

It's an other computer than the desktop I use for everyday work and on which I tested the LiveDVD  but on which I did not yet install Mageia 7 ... (always careful for a production computer ;-)  )

https://www.shlomifish.org/Files/files/video/KPatience%20Solving%20a%20FreeCell%20Deal%20Automatically-K-AU6yiV0FM.webm

It's exactly the same garbage display as with the LiveDVD (comment 46):
no need for a new attachment

its graphical card is nVidia too
I use the nouveau driver

Hi
Last news
I tried openSuse Live DVD (Leap 15.1)
I used VLC 3.0.6 (out of box) to read the webm file provided by shlomi 
https://www.shlomifish.org/Files/files/video/KPatience%20Solving%20a%20FreeCell%20Deal%20Automatically-K-AU6yiV0FM.webm
No problem

I updated VLC to 3.0.7 with its dependancies
There's no problem to read it

NB the openSuse Live DVD uses nouveau


To sum up this bug report 


A)   For Mageia7
1) with the beta release of Mageia 7 (see initial bug report)
VLC 3.0.6 couldn't read the webm file

2) with the final release
VLC 3.0.7 in Mageia7  can't correctly read the webm files on my computers
whatever LiveDVD I use (Plasma or Gnome) whatever graphical driver I use (nouveau or nvidia)
even after having updated them

Once installed and updated the problem is the same (with nouveau or nvidia)
VLC 3.0.7 can't read correctly these files

B)  For Magiea 6
On the same computers using Mageia 6 installed 
VLC 3.06 can read the webm file
Updated to VLC 3.0.7 it can read it fluently too

C) For openSuse (Leap 15.1)
VLC 3.0.6 can read the webm file
VLC updated to 3.0.7 can read it too


D) on these computers whatever Distro I use (installed or from LiveDVD)
Every player I try (mplayer, parole, mpv, Totem, Dragonplayer, xplayer)
can read normally the webm file


Conclusion it seems to be specific to Mageia 7 :
it began with VLC 3.0.6 in Mageia 7 beta 
Is there something wrong in the spec file or in the BR (deleting libvpx and adding aom since Mageia 7 Beta)

NB openSuse uses BR aom AND libvpx 1.8.0 
(without any patch since VLC 3.0.7 : a patch was needed for VLC 3.0.6 to build with libvpx > 1.5.0 ... see https://gitlab.alpinelinux.org/alpine/aports/commit/4ecf0bf5a8c21bb6890de94d9285aa51aaa00f67)  
This patch is no more needed now ... see https://git.busybox.net/buildroot/commit/?id=04efb17c863606cdbc2405d01c3d48d6868c5245

Maybe try to rebuild VLC 3.0.7.1 with libvpx enabled in cauldron/core/testing repo and tainted/repo and mageia7/core/update/testing repo (I will try it for Mageia 7)

Hi 
I tried the last security update (to VLC 3.0.8)
The problem persists for Mageia 7 (but doesn't exist in Mageia6)

Hi Shlomi

Last news about this mystery :

I built my own VLC packages using the 3.0.8-1 srpm (modifying a little the spec file)

1) firstly I built it enabling vpx in the spec file (adding vpx in the BR)
keeping aom
the problem remains for the video test file you proposed :
https://www.shlomifish.org/Files/files/video/KPatience%20Solving%20a%20FreeCell%20Deal%20Automatically-K-AU6yiV0FM.webm

2) for a second try I built it with vpx but without aom
The problem persists

For the two tests I suppressed the config files before using VLC letting VLC writing its default config files

I don't understand what causes this bug specific to Mageia 7 whatever version of VLC I try since Mageia 7 beta2  (VLC 3.06, VLC 3.0.7, VLC 3.0.8 ):
When for these version :
It's OK for Mageia 6
Il's OK for OpenSuse

Try disabling hardware acceleration on Codecs section, maybe a issue with mageia version and your hardware

Hi katnarek

I already tried quite everything for Mageia 7 (Live DVD since beta2, rc and final release or installed)
with vlc 3.0.6, 3.0.7, 3.0.8
in the codec section :
disabling hardware acceleration
or using VDPAU
or using VA-API

in the video output :
output OpenGL
or output X11
or output Xvideo
or output VDPAU

Using nVidia proprietary drivers
or using nouveau drivers

rebuilding vlc with BR vpx and aom
rebuilding vlc with BR vpx without aom

No way !

It's the same hardware on the two computers on which Mageia 6 and VLC (3.0.6, 3.0.7, and 3.0.8) work well 
and on which OpenSuse tumbleweed Live DVD and VLC 3.0.6 and 3.0.7 work well too


It's a real aporia

I can confirm that the video URL'd in c50 does *not* play correctly with VLC (tried under Mate) on my M7 system, which has AMD/ATI/Radeon video.

it shows correctly with: Videos/Totem, Xplayer, Parole, but crashes xine after starting - as per comment 10.

@Philippe : is the matroska issue still outstanding, or fixed ?

Hi Lewis

The issue with matroska or webm videos remains with Mageia 7 fully updated

(vlc 3.0.8-1 tainted with all its plugins)

Thanks for the clarification, if sad news.

Hi
Would it be possible to get the vlc stuff (vlc and its plugins) updated to version 3.0.10 for Mageia 7 
(it was imported for cauldron 6 days ago)

So we could test it with the problematic Webm or matroska videos

Thanks

Source RPM: vlc-3.0.7 => vlc-3.0.8
Summary: last VLC can't display some webm or matroska video files (with mageia 6.1plasma liveDVD it could) => VLC can't display some webm or matroska video files (inside mageia 6 it could)

vlc 3.0.10 pushed to MGA7 updates_testing. In cauldron, experience is much better : hardware acceleration can be left to auto, it plays nicely 1080p and 4K movies with much less CPU usage. I hope this does not depend on more recent libraries than those in MGA7...

Hi Jose
And many thanks to have so quickly answered and pushed VLC to testing

And You know what ?

It's OK now  ;-)

VLC 3.0.10 in Mageia 7 can read everything without any problem particularly the problematic webm or matroska files that couldn't be read whatever I tried to do 
(modifying config , changing video driver from nvidia to nouveau or even rebuilding from source after having modified the BR)


And I still can't understand why every previous versions didn't work in Mageia 7 , when these versions were OK for Mageia 6 or OpenSuse (built with the same source)!
and why it can now without any change in the spec file...

Whatever, it works and let's be happy

This one year old bug may be closed as RESOLVED (at least for me : Mageia 7 x86_64, nVidia graphic card with nvidia non-free driver)

Fixing as bug 26467 will allow to push this update.

Status: NEW => RESOLVED
Resolution: (none) => FIXED
