Re:Link to MPEG-4 Standard (which is based on QT) (Score 2)

If only it were so easy to find that standard in detail on the web. That is merely an overview of MPEG-4. The actual in depth standard specification you have to buy from International Standards Organization. In the last two months I have been SCOURING the internet for MPEG specs. The closest I have come to attaining the information I was looking for was in berkeley's mpeg code. and other sources like Cornell's DALI Multimedia Virtual Machine. But you simply cannot find a page that tells you BIT-by-BIT MPEG-1 formatting. Try it. You might find a page of source code that you could cryptically intepret it. But ISO or someone has gone through great trouble to make online referrences dissapear I would imagine. The closest nitty gritty you can get to on MPEGs are a block-by-block diagram of how the stream is composed. But not header sizes or anything to that effect. Another good example which somewhat relates to MPEG is VideoCD. Sony and Philips hold the licenese to just about all of these specs (White Book being the one at handle). You can find information on what data/sector mode a VCD is written in. What time tracks the special first track ISO is written in. But someone find me a like to how the 'ENTRIES.VCD' file is laid out byte-by-byte. or INFO.VCD.. of Overlay graphic text.. or how to implement any of these features of VCD 2.0. Its not there.. your options: buy White Book for 200$ and sign an NDA -- which kills the prospect of opensource. vect0rx
