10bit mkv - good sound, video all green ?

Hello,

Windows 7 64bit SP1
K-Lite Codec Pack 9.8.5 (Full) 32bit
Player: Media Player Classic v1.6.7.7036 (the same included in 9.8.5 package)

So I noticed that some mkv videos not playing - good sound, video all green. These files all were 10bit(all 8bit mkvs play fine).
MediaInfo output:

Any ideas ?

Which video decoder is listed under Play > Filters? You probably have a H.264 decoder installed that can't handle 10-bit properly. The pack uses LAV Video decoder by default, and that handles 10-bit perfectly. Sometimes other decoders have very high merit and can get used instead. I can give instructions on how to disable the broken decoder once I know that is the cause.

Hi,

It's LAV Video decoder - I also see red LAV icon in my notification area.

Vilius M.

Did you change any of the video renderer settings in MPC-HC?

Try resetting settings with the Codec Tweak Tool.

Hello,

I had some time to investigate - so I will revive this for now.

It happens only if components/conditions are:
Matrox_M9128_Card + K-Lite_MPC_Player + 10bit_mkv_Video
result is framed green picture

If one of components described is changed - problem disappears. For example another video card - it plays with no problem, another player like VLC - it plays with no problem, 8bit mkv video - plays with no problem.

Vilius M.

Can you post this information? It is useful to know the exact details of the graphics card and driver.
Codec Tweak Tool > Generate Log > System Information

MPC-HC menu > Play > Filters
Click on the video renderer in the list of active filters. It should be Enhanced Video Renderer (custom presenter), if not let me know.
In the properties window, click on the "Pin Info" tab.
Look at the details of the "EVR Input0" pin. Below "Connection media type" it should show "NV12". Is that correct?

Click on LAV Video decoder in the filter list. In its options window, under "Output Formats" uncheck NV12.
Close the player and test if playback works correctly now.

- Connection media type:
Video: P010 960x540 23.974fps

Checking NV12 on/off changes nothing.

Looks like I found a workaround - disabling 10bit and 16bit LAV video decoder output formats forces MPC to use 8bit - and now it plays 10bit files with no problem.

But some bug still exists in this configuration.

Seems like a bug in the Matrox driver. It should not be accepting P010 input if it doesn't support that. Your workaround will obviously avoid that problem.

Updating the driver might also fix it. I found a newer version on the Matrox website.
