c++ - Export every frame as image from a Movie-File (QuickTime-API) -
I want to open an existing movie-file and export each frame of this file to an image like JPEG or TIFF . I've got so far away:
int main (int argc, char * argv []) {char filename [255]; // Osir e for filing pn; // error return FSSpec filespec; // QT file specification short file movie; // QT movie handle movie movie; // QT movie "Object" InitializeQTML (0); EnterMovies (); Because of the QT's Mac origin, C-string filename // must be converted to Pascal count string, then use it to create the filepeak. C2pstr (filename); FSMKSSSPC (0, 0L, (Constosters 255 PRAMM) file name, and filepeak); OpenMovieFile (& FilePC, and Phylum, FSRDpram); Pneumovief file (& amp; film, filemovie, zero, zero, newmovieactive, zero); ...
So far it works fine (I have tested with Time Value MovieMatam = GetMovieDuration (Movie);
and print it), But now let me export the frame of each film and file it (for the first time, I want the data to work with it in memory, but I have to know that it actually works, so export the image file now is better ). how can I do this? Do I Need a GWorld or PixMap?
Edit: My Platform is WinXP
In the beginning, this article on Movie exporters should start very much:
Even though MacTech is a Mac resource, all the described API functions are included in Windows Must be available for SDK in Quicktime
As soon as it takes me,
edit
look at this book excerpt for additional information:
Editing 2 - Highly Approach: Movie Exporters
If you need to complete all video frames with a QuickTime Movie Is to remove and convert them to another format supported by the Quicktime API, which you will not use using Movie Exporter Te time someone will take actions to lower levels.
Remove
/ P>
Export the combo box of the dialog and hit Options and choose your desired image format.
Note 1: If you do not have to do this, then just let me know.
Note 2: Error handing for clarity
