It is really the goatse.cx guy (See Wikipedia for more info). The JPG is NOT what is in the correctly encoded (I tested it) non-Alpine APN. The zip file attached contains an APN and JPG file. Using these facts, I think I know why the original poster of this message hasn't said a thing since posting. I also tested taking an Alpine file, splitting it and appending it to itself-it loaded fine. The file on this forum can be split exactly in half and the files compare identical. It may play on rear displays, I don't have one. * I think the second file is for a different aspect ratio and/or maybe PAL. * The duration of the files tends to make it hard to see but Windows Media player does play both frames * Windows Media Player will play the files if you have "Nero Video Decoder" installed by Nero 7 Ultra Edition (and maybe other versions) ![]() * The files get to be their full size via padding bytes at the end (FF values) * the file must be exactly 64k total (65,536 bytes). * the file is really 2 - 32k files appended together * the data is MPEG2 encoded-likely by a Linux based encoding method Best I can tell it’s not totally correct, but it’s close. I found this page talking about i-Personalize and the specifications of the encoding. After viewing APN files in a hex editor, its fairly obvious that the data is MPEG2 encoded (has the string "MPEG-2 Verification Sequence"). The actual methodology used to encode and decode video with AVC involves three distinct phases labeled "predict", "transform" and "encode." The mechanics of AVC break video down into a kind of machine language that can be easily stored and accessed by a range of technologies. However, experts also point out that the storage efficiency of AVC is greater than those of some previous MPEG formats. ![]() When comparing AVC to MP4, it's important to consider that AVC has a bigger compression ratio and longer encoding than MP4, and that more central processing power is needed. mpg.Įxperts point out that AVC is a prominent alternative to an MP4 format. In terms of its origin, AVC was developed jointly by the International Telecommunications Union (ITU-T) and the Moving Picture Experts Group ( MPEG), which is a project of the ISO/IEC and familiar to many users because of popular and accessible MPEG file formats, like. ![]() AVC helps to set the standard syntax for video formats such as Blu-Ray, mobile TV and teleconferencing. Advanced Video Coding: a type of standard for the compression of digital video.
