copied!<p>As a beginning, this article on Movie exporters should pretty much get you started:</p> <p><a href="http://www.mactech.com/articles/mactech/Vol.16/16.05/May00QTToolkit/index.html" rel="nofollow noreferrer">http://www.mactech.com/articles/mactech/Vol.16/16.05/May00QTToolkit/index.html</a></p> <p>Even though MacTech is a Mac resource, all described API functions should be available in the QuickTime for Windows SDK as well.</p> <p>I will slap some sample code together myself as a reference here as soon as I find the time.</p> <p><strong>Edit</strong></p> <p>See this book excerpt for additional info:</p> <p><a href="http://books.google.com/books?id=Q_LCwa_8-asC&pg=PA121&lpg=PA121&dq=ConvertMovieToFile&source=bl&ots=4pQdHL-w8E&sig=A6OiGPRIV-xvdV7esJxTDUDG1Tk&hl=en&ei=R1wvS8-uC9eGsAbo7-DDBw&sa=X&oi=book_result&ct=result&resnum=9&ved=0CBwQ6AEwCA#v=onepage&q=ConvertMovieToFile&f=false" rel="nofollow noreferrer">QuickTime Toolkit - Basic Movie Playback and Media Types @ Google Books</a></p> <p><strong>Edit 2 - The High-Level Approach: Movie Exporters</strong></p> <p>If all you need to accomplish is to extract all video frames from a QuickTime Movie and convert them to another format supported by the QuickTime API you won't have to take any low-level actions whatsoever if using a <strong>Movie Exporter</strong>.</p> <p>The below sample code allows to extract and convert all video frames from a QuickTime Movie to, f.e., a bunch of JPEG files using a programmatically invoked Movie Export Dialog.</p> <p>Just select <em>Movie to Image Sequence</em> in the <strong>Export</strong> combo box of the dialog and select your desired image format by hitting <strong>Options</strong>.</p> <p>Note 1: If you need to do this non-interactively, just let me know.</p> <p>Note 2: error handling has been omitted for clarity</p> <pre><code>#include "Movies.h" #include "QTML.h" #pragma comment (lib, "QTMLClient.lib") </code></pre> <p>...</p> <pre><code>int flags = createMovieFileDeleteCurFile | showUserSettingsDialog | movieToFileOnlyExport; ItemCount movie_prop_count = 0; CFStringRef cfpath = 0; Boolean bool_true = true; QTNewMoviePropertyElement movie_props[ 2 ]; Movie movie; // initialize QuickTime API InitializeQTML( 0 ); EnterMovies(); // set up Core Foundation string for source path (argv[ 1 ]) contains the full path to the MOV file to convert cfpath = CFStringCreateWithCString( 0, argv[ 1 ], kCFStringEncodingASCII ); movie_props[movie_prop_count].propClass = kQTPropertyClass_DataLocation; movie_props[movie_prop_count].propID = kQTDataLocationPropertyID_CFStringNativePath; movie_props[movie_prop_count].propValueSize = sizeof(cfpath); movie_props[movie_prop_count].propValueAddress = (void*)&cfpath; movie_props[movie_prop_count].propStatus = 0; ++movie_prop_count; // make Movie active movie_props[movie_prop_count].propClass = kQTPropertyClass_NewMovieProperty; movie_props[movie_prop_count].propID = kQTNewMoviePropertyID_Active; movie_props[movie_prop_count].propValueSize = sizeof(bool_true); movie_props[movie_prop_count].propValueAddress = &bool_true; movie_props[movie_prop_count].propStatus = 0; ++movie_prop_count; // aquire Movie for our Movie file NewMovieFromProperties( movie_prop_count, movie_props, 0, 0, &movie ); // invoke conversion dialog ConvertMovieToFile( movie, 0, 0, 0, 'TVOD', 0, 0, flags, 0 ); // clean up DisposeMovie( movie ); CFRelease( cfpath ); ExitMovies(); TerminateQTML(); </code></pre> <p>...</p>
