How can I load Jpeg image from disk and create video file (.avi etc) without using opencv in c++
<p>I am trying to load JPEG images from disk and create video file from them but I am unable to do this. I was successful in creating video file of BITMAP Images by using HBITMAP handler but the size of Bitmap Images is mush greater so I want to make video with Jpeg Images.</p>

<p>here is my class for converting bmp images to avi file:</p>
