How do I get them out of their files?          BorlandTalk.com Forum Index -> Delphi Multimedia View previous topic :: View next topic   Author Message MasterPeter Guest Posted: Fri Jan 26, 2007 7:33 am    Post subject: MPEG / AVI Frames. How do I get them out of their files? I have developped my own movie file structure and a player to go with it. Now I just need to try converting some of the existing video files I have into my format. What is the file structure, or how do I access the individual frames? I have not been too worried about the audio part of it, maybe later, but sofar I am glad to have the video-bit runnig quite nicely. Can anyone offer help, or maybe just a useful link?

Hi, If you want to extract frames from MPEG-2 file you have to demultiplex (ISO/IEC 13818-1) the file to elementary streams. Then you can read about the frames in the video elementary stream in (ISO/IEC 13818-2). (ISO/IEC 13818-1) describes the multiplexing rules also for MPEG-4, AVC/H.264 in Program Stream and Transport Stream. You can try my MPEG TS Utils, MPEG PS Utils and MPEG Video ES Utils, regarding MPEG-2 multiplexing and MPEG-2 video stream structure. About the frame structure of MPEG-4 you can refer to (ISO/IEC 14496). Information about the AVI container you can find in MSDN. There are also a lot of sources available on these issues - VLC(www.videolan.org), ffMPEG... You may also consider the QuickTime container. Look for the qtff.pdf freely available on the www.apple.com. You can also try my QuickTime Atom Viewer for the visual representation of this container.
