Answer 1

You are only passing the file path ( nativePath ) to Facebook, instead try passing the actual image blob like this:

var blob=f.read();
var data={
    message: 'Check this video!',    
    video: blob
}
// The rest....

Here is the answer #

            var url = "https://graph-video.facebook.com/me/videos";
            Titanium.Facebook.authorize();
            var xhr_video = Titanium.Network.createHTTPClient();

            xhr_video.open('POST', url);

            xhr_video.setRequestHeader('Content-Type', 'multipart/form-data');

            xhr_video.onload = function(e) {

                alert("Video Has Been Successfully Posted to Your Timeline");

            };
            xhr_video.onerror = function(e) {
                alert(e);
                xhr_video.abort();

            };
            var f=Titanium.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory+"/"+"audio"+"/"+"video.mp4");
              var blob=f.read();
            var data = {
                video : blob,
                //access_token : Titanium.Facebook.getAccessToken()
                access_token:Ti.Facebook.accessToken
            };
            alert(data);
            xhr_video.send(data);
