Bug 19299 – QTMovieWin should not hard code supported MIME types

• Component: Plug-ins
• Status: RESOLVED FIXED

[Eric Carlson]

QTMovieWin currently has a hard coded list of MIME types. The list doesn't include many common types supported by a default QuickTime install (eg. "audio/mp3" or the many other MP3 synonyms), but it also means that WebKit won't list types added by third party movie importers (eg. the ogg importers).

Looks good. Some style comments, I guess this was adapted from existing code. 

+    ComponentDescription    findCD;
+    QTAtom                  mimeTag;
+    Component               comp;
+    char                    *atomData;
+    int                     index;
+    long                    componentCount;
+    OSErr                   err = noErr;

+                QTAtomContainer         mimeList = NULL;
+                ComponentDescription    infoCD;
+                int                     typeIndex, typeCount;
+                long                    typeLength;

WebKit code doesn't usually align variable names like this.

+                // grab every type from the container
+                QTLockContainer(mimeList);
+                typeCount = QTCountChildrenOfType(mimeList, kParentAtomIsContainer, kMimeInfoMimeTypeTag);
+                for (typeIndex = 1; typeIndex <= typeCount; typeIndex++) {
+                    if ( 0 != (mimeTag = QTFindChildByIndex(mimeList, 0, kMimeInfoMimeTypeTag, typeIndex, NULL))) {

Extra space after (
It would be better to do assignment separately from comparison.
This and the next if could use continue instead, reducing code nesting.

+                            if (0 != strncmp(typeBuffer, "audio/", 6) && 0 != strncmp(typeBuffer, "video/", 6))

0 != is unnecessary

+                            for ( int addedIndex = 0; addedIndex < gSupportedTypes->size(); addedIndex++ ) {

extra space after ( and before  )
