ios - Unable to saving a video to photo library -

here's code:

alassetslibrary *library = [[alassetslibrary alloc] init]; nsurl *videourl =[info objectforkey:uiimagepickercontrollermediaurl]; if ([library videoatpathiscompatiblewithsavedphotosalbum:videourl]) { [library writevideoatpathtosavedphotosalbum:videourl completionblock:^(nsurl *asseturl, nserror *error) { if (error) { nslog(@"error"); } else { nslog(@"video asseturl %@", asseturl); } }]; } else nslog(@"videoatpath not compatible photos album.");

the videourl file:///private/var/mobile/containers/data/application/b1f512ea-6d13-4df1-86db-f6166f0d533f/tmp/capture-t0x17511a30.tmp.pg4pbh/capturedvideo.mov

i maintain getting error when saving video saved photo album. , homecoming message:

the error message says file doesn't exist, possibilities are:

file address not correct, can check sandbox of app see whether video file physically exists. if exist, check whether video valid , playable. invalid video rejected saved album.

or capture module didn't work, expecting file written in directory, didn't happen because capture failed.
