c++ - FFMPEG - Read video file and convert to Bitmap -

i can read video file using ffmpeg

now want show these video frames on mfc mdi.

for need bitmap feed cbitmap::fromhandle() function

memdc.createcompatibledc(dc);  cbitmap * bmp = cbitmap::fromhandle();  cbitmap * oldbmp = memdc.selectobject(bmp);  dc->bitblt(0,0,320,240,&memdc,0,0,srccopy); 

for ffmpeg using dranger tutorial 01

http://dranger.com/ffmpeg/tutorial01.html

please advise how convert frames bitmap

thanks

i have been working on last 3 days , gotten far

now frames bitblt dc upside down

please let me know if there wrong code
