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.
