Hello,

in this case it could be more likely that the driver of the video card is not compatible with a specific DirectShow filter named InfinitePinTee (from Microsoft) that we use to allow rendering the video clip on multiple windows at the same time. This filter is inserted between the LAV codec and the video renderer but, unfortunately, many times the output format of this filter is not managed correctly by the video driver. The strange thing is that we have a Windows 10 laptop with same driver and it works just fine.

Could you be so kind to send us a log generated through the DxDiag.exe utility on the troublesome machine? This utility is usually installed inside the \Windows\System32 folder.

Kind Regards

Hello Severino,

I agree with your explanation.

But the fact is This Laptop only support Microsoft decoder only. It gives proper video scaling with this decoder.
With other decoders video is not played. It is not even displayed or do not move. (Remains standstill)
Obviously i am facing problem with Brightness and contrast functions which do not work with Microsoft decoder.

I updated drivers (Intel Graphics HD 5500) and it shows they are up to date.

Is that means K-lite decoders like LAV, ffdshow are incompatible with Intel Graphics HD 5500?
Should i address this issue to K-lite codec ?

Please advise me.

Regards,

Ravindra.

Hello Ravindra,

Microsoft's codecs are not the best choice because they are specifically designed for DVD playback and come with a lot of limitations: as far as I can remember they don't come with support for the YUY2 color space.
Usually LAV codecs are quite good, stable and well maintained by their developers but it must be kept in mind the fact that DirectShow must deal with video drivers also which, especially on laptops, may not have the best quality ever. You may check with your laptop's manufacturer the availability of an updated driver.
As an alternative to LAV codecs, you may try with the ffdshow set of decoders which are installed by K-Lite as well and which come with support for the H264 format: this set is usually disabled by default and require to be enabled manually through the "Codec Tweak Tool" item accessible through the K-Lite's Windows menu.

Hope this helps

Kind Regards

Hello Severino,

I added brightness, contrast control in my program.
These functions work on development machine.
(Windows 7-64 bit, i3 processor, 8 GB ram and Intel(R) Graphics)

I am trying to deploy it on laptop with following configuration,
OS: Windows 10 - 64 bit.
CPU: i7-5500
Graphics: Intel HD 5500
               Nvidia GEForce 940M (3D)
Ram: 8 GB

I installed K-lite codec pack with default settings.

I am facing a problem that my video becomes small in size (occupies only 3/4 of lablevideoposition)
But my brightness contrast functions work.

On the other hand if i change codec settings and change H.264 setting to Microsoft from LAV.
my video occupies full window but brightness and contrast functions doesn't work.

My video is made with H.264 video codec. I also tried with MPEG4 but it doesn't solve the the problem.

The brightness and contrast functions supported only by H.264 with LAV ?

This problem persists only with this laptop.
Elsewhere everything works fine but PC's / Laptops are with i3 processors and Intel Graphics without nvidia.

Any suggestions ?

Regards,

Ravindra.

Hello Severino,

Thanks a lot for your perfect guidance.

I installed K-lite codec pack on my development machine.
Everything was working irrespective of this codec initially except for image adjustment.

Now i can adjust image.

Regards,

Ravindra.

Hello,

it's likely that the video format in use, or the codec used to manage the same, doesn't support the YUY2 color space.
Do you have a sample of video file, not working on your PC, we could download for testing?

Kind Regards

This is my development machine only.
Please guide me what i am supposed to do ?

Hello,

yes, the VideoPlayer.ImageAdjustEnable method allows enabling image adjustments for video formats that support the YUY2 color space as seen inside the documentation of the same method.
The VideoPlayerAdvanced sample of the DJ Studio component demonstrates how to use it.

Hello Severino,

Thanks for guidance.

After doing some work around i changed settings of K-lite codec and problem was resolved.

I changed the video driver settings for H264 to Microsoft.

Regards,

Ravindra.
