PJPEG, Photo JPEG, Progressive JPEG?

Hi,

I’m sorry for going a little of topic.

I’ve been reading about CPU friendly video playback and I read a lot about using PJPEG. But after heavy search on the web I still didn’t fin how to convert to this format (without downloading sketchy software).

It would be great if I could get some suggestions on how to convert into PJPEG.

Thanks for your time!
