No Video in Playback Only Audio

by BradleyFreakin Sun Aug 16, 2015 9:39 pm

So I am on Windows 10 and just installed the Codec Lite Pack and thought it would solve my problem but it didn't. Ever since I got Windows 10 I have had no video during any video on any player. Online videos work fine. The solution to this in the FAQ is:

"First open the file with the MediaInfo Lite tool to verify that it contains video. Then open the file with the GraphStudioNext tool to verify that the source filter detects a video track and that a video decoder is being loaded."

Where can I find these tools? I cannot find them in the Codec Tweak Tool. Here is my log for further analysis of the problem.

MediaInfo and GraphStudioNext are not included with the Basic version of the pack, only with the larger versions. But you don't need them. Your problem is not because of a missing codec, but because of your graphics driver. There are a lot of issues with AMD driver, specially on APU systems like yours.

I suggest you try with Media Player Classic that is included in the Standard version of the codec pack. If playback also fails with that, then try a different video renderer. Media Player Classic options > Playback > Output.

If nothing works, then you could temporarily switch to the "Microsoft Basic Display Adapter" driver until AMD fixes their crappy drivers.

Right-click on Start > Device manager > Display adapters > Right-click on your AMD Graphics > Update driver software > Browse my computer ... > Let me pick from a list ... > Microsoft Basic Display Adapter

So this entire problem is based on the fact that AMD hasn't updated their drivers for Windows 10? Wow. Tried using the optimized MPC and it worked. Thanks man.

They did update their drivers for Windows 10, but the current drivers are simply not working correctly yet in all cases. Windows 10 should automatically update your drivers when new versions are available. So hopefully AMD improves things soon.

Last thing. I am also trying to find a video editor that can do very simple things. (Ex: Windows Movie Maker)
When I load any video in pretty much any editor I get the same problem. Audio but no video. Is there a way I can install the Codecs to like Movie Maker somehow?

Once the playback is fixed, things should start working in Movie maker as well.

Have you tried using "Microsoft Basic Display Adapter"? You can always switch back to the AMD driver later.

Playback only works correctly now in MPC. Tried Microsoft Basic Display Adapter. It works but pretty much puts my videos at 5 frames per sec

Try this registry tweak. It will disable hardware acceleration for the Microsoft video decoder:

Code:: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Scrunch\CodecPack\MSDVD] "DXVA2"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Scrunch\CodecPack\MSDVD] "DXVA2"=dword:00000000

Do I type that in to regedit or cmd or something? Sorry, no too familiar with registry stuff

by **Admin** Thu Aug 20, 2015 11:28 pm

Yes, you can do it with Regedit.

Okay, I must be dumb because I cannot figure how to import that to Regedit. I tried saving that code in Notepad as a .reg file and importing it to Regedit but that didn't work. I'm not seeing the "Scrunch" folder

by **Admin** Sat Aug 22, 2015 10:04 am

This should work for a .reg file:

Code:: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Scrunch\CodecPack\MSDVD] "DXVA2"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Scrunch\CodecPack\MSDVD] "DXVA2"=dword:00000000

I dont think you understand.
MACHINE\SOFTWARE\Microsoft\Scrunch\CodecPack\.....
Scrunch folder does not exist on my computer, therefore you cannot edit a file that doesn't exist

by **Admin** Sun Aug 23, 2015 1:06 am

That folder will be created automatically.

The reason your .reg file failed to import previously was because the first line was missing.

I just created a new thread for this without noticing this thread, i have deleted it but i also have this issue, here is a description of my problem. I'm using an Nvidia GPU too.

Hi everyone,

Was going through my videos last night to make sure all played correctly using the standard version of K-Lite codec pack and noticed that sometimes when I click to play an MKV file it just shows a blank window in WMP and no video (the default blue colour of the interface) but I can hear the audio. If I click to play an MKV file initially it plays fine but if I go back into the library and select a different video it will show no video, if I hop in and out of ‘now playing’ whilst the video in error is playing the video re-appears, It also seems to have no problem playing MKVs if I ‘skip’ to the next video. I tried to mess with the codec tweak tool because MKV support is now native in Windows 10 so I was trying to make LAV play the MKV and not Windows to see if it was a Windows problem, but no setting I changed made any difference, even if I uninstall the codec pack it does it.

Does anyone have any ideas? Thanks.

This is the only change needed to use LAV
Codec Tweak Tool > Media Foundation > disable for .mkv

Unfortunately this doesn't work, it seemed to work then just went back to normal behaviour.

If you can make the video appear by just switching the view in WMP, without restarting playback, then it must be some kind of display bug in WMP, not something related to the codecs.

by **Admin** Fri Aug 28, 2015 8:36 pm

The WMP library is very buggy, even on older versions of Windows. For example seeking is broken for non-native file types when opening from the library, while playback is perfect when opened from Explorer. Solution in that case is to create a playlist for the files. Then seeking works.
