Avi codec windows 8
The most prominent feature of this application is that it is compatible with a wide range of audio and video file formats. Moreover, it is a lightweight tool that consumes very little system memory space. It works in the background so you can continue with your important tasks. This is the reason why it won’t slow down your PC. K-Lite Codec Pack doesn’t require plenty of system resources to operate. However, this codec pack is the right solution for you due to its efficient nature.
AVI CODEC WINDOWS 8 INSTALL
When you install a new application, particularly a codec pack, it’s natural to worry whether or not the application is resource-friendly. While installing it, you can modify its settings to best fit your needs. Developers frequently release its updates to ensure it’s compatible with the latest file formats.

You can quickly download and install it on your PC and get free to play videos, music, and movies of any and every format. Obviously in a real application, you'd need to write a real RLE8 encoder, but this proves the point.K-Lite Codec Pack is a comprehensive set of audio and video codecs. If (AVIStreamWrite(pStream, frame, 1, bits, i, 0, NULL, NULL) != 0) unsigned char *bits = new unsigned char įor (int frame = 0 frame bmiHeader.biHeight y++) Instead we write RLE8 encoded data to the raw stream. We do still need to create the compressed stream, but we no longer write to it.
AVI CODEC WINDOWS 8 CODE
Starting from the code in the question, we need to keep it all, and replace the innards of the for loop that writes the frames. I can confirm that performing the RLE encoding manually is easy to do, and works well.
Thanks to Roman for suggesting some ideas to work around the problem. It seems likely that this is indeed a bug in Windows 8. Is it possible to use Video for Windows on Win8 to create MRLE encoded. So there are good reasons why I am reluctant to try to use one of the more modern multimedia APIs until I can be sure that Video for Windows on Win8 with MRLE is a lost cause. And the MRLE codec is available by default on all versions of Windows that I support. However, the frames that I am encoding are very amenable to run-length encoding. I know that Video for Windows is an ancient legacy API. If I generate the file on Win7 and view on Win8 then the video displays as desired. If I generate a file on Win8 and view on Win7 then the file does not play correctly. But on Win8 the video just contains the first white frame. This happens as expected on Win7 and earlier. So the desired video transitions from white to black. And each frame selects a different one of those gray shades. Std::cout << "AVIFileRelease failed" << std::endl Std::cout << "AVIStreamRelease failed" << std::endl If (AVIStreamRelease(pCompressedStream) != 0 || AVIStreamRelease(pStream) != 0) Std::cout << "AVIStreamWrite failed" << std::endl
If (AVIStreamWrite(pCompressedStream, frame, 1, bits, bmi->bmiHeader.biSizeImage, 0, NULL, NULL) != 0) If (AVIStreamSetFormat(pCompressedStream, 0, bmi, bmiSize) != 0)įor (int frame = 0 frame bmiHeader.biSizeImage) Std::cout bmiHeader.biSize = sizeof(BITMAPINFOHEADER) īmi->bmiHeader.biWidth = si.rcFrame.right īmi->bmiHeader.biHeight = si.rcFrame.bottom īmi->bmiHeader.biSizeImage = bmi->bmiHeader.biWidth*bmi->bmiHeader.biHeight If (AVIFileOpenA(&pFile, "out.avi", OF_CREATE | OF_WRITE, NULL) != 0) I've made an SSCCE to demonstrate the problem: #include avi file but when it is viewed in, for instance, Windows Media Player, the video plays for the correct duration but the first frame is shown the whole time. This has worked admirably for many years, but I've just discovered that my code does not behave correctly on Windows 8. I have an old application that provides videos inside.
