This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
NSSharingService *service = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail]; | |
NSDictionary *parameters = @{ | |
@"NSSharingServiceParametersDefaultSubjectKey": @"Lo, a subject!", | |
@"NSSharingServiceParametersDefaultRecipientsKey": @[@"[email protected]"] | |
}; | |
[service setValue:parameters forKey:@"parameters"]; | |
[service performWithItems:@[@"Woo, private API."]]; |
