6. Frequently asked questions about VLLC on Windows

  • 6.1 Why does VLLC only give black, white or garbled (or other visual errors) video output?


    Usually the problem lies in display adapter drivers. If you are too scared to update your display adapter drivers, you can change VLLC settings to make video work. If you are using Windows XP or older, the easiest fix is usually to disable Accelerated video output/Overlay video output which can be found first opening Tools -> Preferences and then choosing Video. After you have unticked the Accelerated video output, press Save to save VLLC settings and restart VLLC after that to make sure changes are enabled.


    If disabling Overlay video output doesn't help, then the next step is to change video output module (aka VOUT). Open Tools -> Preferences (set Show Settings to All) and then choosing Video -> Output module. There are multiple output modules you can use. For Windows XP and younger you can try DirectX 3D, DirectX, OpenGL and Windows GDI video output modules. With Windows Vista and with Windows 7, both DirectX and Windows GDI output modules will disable Aero, so if you want to use Aero, please use DirectX 3D (should be default). Remember to press Save to save VLLC settings and restart VLLC after that to make sure changes are enabled.


    6.2 Video shows green, blue or red lines


    See above.


    6.3 How can I adjust brightness or contrast?


    You can adjust brightness, contrast and other settings via Extended settings. Open Tools -> Effects and Filters to adjust these settings (Video Effects -> Essential and tick Image adjust). Changes should show up realtime.


    6.4 How can I keep the brightness and contrast adjustments in memory forever?


    Open Tools -> Preferences (set Show Settings to All) and then choosing Video -> Filters -> Image Adjust and set values you want to use (trial and error).


    6.5 Can I set file specific brightness or contrast?


    Yes, but it isn't that easy. You have to create a VLLC shortcut or .bat file with the proper settings.


    6.6 How do I set the default deinterlace method?


    Tools -> Preferences (Show settings: All) Video -> Filters and tick Deinterlacing video filter from under Video output filter module (NOT FROM UNDER Video filter module!). Then Video -> Filters -> Deinterlace and choose the default mode. Remember to press Save to save VLLC settings and restart VLLC after that to make sure changes are enabled.

    6.7 VLLC crashes or gives garbled images when using VMWare or VirtualBox


    This is due to buggy direct3d/video emulation. Use the GDI video output in the preferences to work around this.


    6.8 Crackles, pops, hisses and other audio anomalies


    If you hear some unwanted audio problems you can try another audio output module to see if that solves the issue (Save and restart VLLC after changes). Open Tools -> Preferences (set Show Settings to All) and then choose Audio -> Output module. There are multiple output modules you can use for audio. DirectX and Win32 waveOut should work in most cases. Unfortunately VLLC doesn't support ASIO.


    6.9 Crackles, pops, hisses and other audio anomalies with SPDIF passthrough


    SPDIF passthrough of Dolby Digital (AC3) and DTS audiotracks don't work with all soundcards. The Win32 waveOut output module should work better with SPDIF.


    6.10 I don't hear dialog, conversations, etc. while playing 5.1 audio


    Make sure you have selected the proper speaker setup from Windows audio settings or from the soundcard control panel. If you have done so, make sure VLLC also has right settings. Audio -> Audio Device to select proper speaker settings during playback.

Then when playing the video go to Audio -> Audio Track -> Track 2 to select the second (or whichever it is) audio track (this so-called "Slave-mode" doesn't work correctly).


    6.13 How do I change my output device in case I have multiple audio devices connected to my PC?


    Open Tools -> Preferences (set Show Settings to All) and if you use DirectX, then Audio -> Output modules -> DirectX and Output device. If you use Waveout, then Audio -> Output modules -> WaveOut and Select Audio Device. Remember to press Save to save VLLC settings and restart VLLC after that to make sure changes are enabled.


    6.14 How can I override speaker setup? (e.g. I want to always default to stereo)


    You can force speaker setup if you use DirectX audio output from Tools -> Preferences (set Show settings to All) Audio -> Output modules -> DirectX and Speaker configuration dropdown menu. Remember to press Save to save VLLC settings and restart VLLC after that to make sure changes are enabled.
