Crash on 4K UHD in 3.0.x

[hwo333]

Hi,

I downloaded some 4K videos from Youtube. The last VLC version that can play these videos is 2.2.8. When I open a 4K video in version 3.0.0 to 3.0.5 (64 bit), VLC crashes. The next time I start VLC, I get a message that a bug occurred last, with the question if I want to send a bug report to the VLC team.

Has anyone noticed the crash yet?
RealPlayer Cloud and Windows Media Player can play these files.

Windows 8.1 Home 64 bit, 8 GB RAM
AMD Radeon HD 7650 M, 2GB
1920 x 1080

There is no message about this in Event Viewer.
Are there any logs I could check?

Hi, you could try to grab the logs with the following procedure:

To help you, we need messages, to completely understand what your problems is.

From windows command line or linux or macos terminal, launch vlc with options -vv and --logfile=file

• Windows example: vlc.exe -vv --logfile=c:\vlclog.txt
• Linux example: vlc -vv --logfile=vlclog.txt, or vlc -vv 2>&1 > logfile.txt

Then paste the full resulting log here between [​code]and[​/code] (or use Pastebin.com if it's too long)

Also don't forget to name your Operating System and provide the VLC media player version.

It would help to know what happened and fix the issue.

After this, you can probably fix this issue by switching renderer and/or disabling hardware acceleration until it is fixed (but it might not be able to decode 4K video anymore).

If you're using VLC 3.0.x and have video issues.
Try:

1. Preferences -> Input/Codecs -> Disable hw decoding
2. If you are a Windows user, Preferences -> Video -> Change from direct3d11 to direct3d9

If any solution works, please tell us which one solved your case, Please also quote your video driver name and version.

Hi,

A log file wasn't created.

Command: vlc.exe -vv --logfile=d:\temp\vlc.txt

VLC Player opens, then I load the mp4 file via menu and VLC crashes without a message and no log file.

Then in Settings / Video I changed the ouput from automatic to Direct3D9 (Direct3D11 is also available) and in Settings / Input/Codecs I changed HW acc from automatic to DirectX Video (DXVA) 2.0. Both settings must be set to prevent VLC from crashing (anything other than Direct3D11). The videos will be played.

DxDiag tells me the following:

Thank you for your help. If you have another suggestion to get any log output let me know.

The 2 problems still exists in Version 3.0.6.
With command "vlc.exe -vv --logfile=d:\temp\vlc.txt" won't be created a file and VLC Player crashes when opening a 4K mp4 file if Input/ouput codecs are set to Direct3D11 or Automatic.
