> If avi video file contains pictures in jpg format then how extract frame and convert to BMP? > I want use video avi without DirectShow and MediaFoundation You need: * RIFF / AVI file format spec http://en.wikipedia.org/wiki/Audio_Video_Interleave * "FourCC" codec list (one of them should hold independent JPG's ...) * JPEG compression algorithm and file format (a bit messy) (you will have to 1. decode "markers", 2. Un-Huff, 3. Un-RLE, 4. IDCT, 5. Un-subsample, 6. YUV->RGB) * BMP file format Start with MediaInfo ... it will tell you what's inside your AVI (note that DiVX or WMV or XXX264 ... etc is more than just a bunch of JPG's). |

I think but not sure this can help you :
You need a .inc file with interfaces to DirectShow. You need also to call this basical interfaces , like : BasicVideo , VideoWindow and /xor MediaControl ,MediaEvents ... |
