Pavithra,

First of all I am curious to ask why do you want to do this. If you want to save your video data in a compressed format, you can use VideoWriter to select from the many compressed formats options that it supports.

If this is not your intention, you can use RLE to perform this encoding. I am not sure how you can save this data though.

Up to now no person have send the cose to compress a video losslessly ?

Use mmfileinfo() to get information about the size of the frames. Write that out to a binary file. Loop over the frames, calling the RLE routine that Dinesh Iyer linked to above. Write the run length compressed information to the binary file. Continue going until all frames have been processed. Close the binary file. You now have a losslessly compressed video.
