Even after installing K-lite codec I am not able to play the video only the black screen is seen with some errors

Please paste the error message, and upload the video file here that you try to play.

There is one more thing to add. In my olden project that is working fine in other laptops but even videos in older exe which works in other device is not working in my device so I feel that it might be due to codec so i installed k lite codec but even that is not working can you suggest what should be done and where's the issue?

[jakky1]

@moxil198, since you said the same video file can be played in other laptops, but cannot play in your device, I have no idea how to fix it.

If this problem bothers you, please use other packages instead ... orz

Bro let me explain it in more detail:

I built an exe and installed it on another PC it works perfectly fine but when I try to run the same exe even after installing the K lite codec it is not playing the video.

Getting below details might help me:

1. exactly ehich codec extension is required to run the video
2. What is the process in K lite codec I mean which option we need to turn on.
3. Are there any other softwares for that?

[jakky1]

So, with the same exe, and the same video file, it can be played in device A, but cannot be played with device B with K-lite codec installed, right ?

You should upload the video file here. I cannot know which codec this video file uses before I got the video file.

The video file contains AVC (H.264) video and AAC (audio). Both are supported by K-lite codec pack. It can be played in my PC with this package.

Maybe you can try the following steps:

• un-install K-lite codec pack
• then install again. Check all the options related to AVC / H.264 if present.
• In the K-lite codec pack download page, there are 4 versions : Basic / Standard / Full / Mega. Please try Mega version instead.
• Hmm... if it still not working, maybe considering re-install your Windows...

If it still not working, I have no idea how to fix it :(
