Two ways for iOS to get a specified frame in a video

Method One: Avfoundation

1 #import<AVFoundation/AVFoundation.h>2 3-(UIImage *) Thumbnailimageforvideo: (Nsurl *) Videourl attime: (nstimeinterval) Time {4Avurlasset *asset =[[Avurlasset alloc] Initwithurl:videourl Options:nil];5 Nsparameterassert (asset);6Avassetimagegenerator *assetimagegenerator =[[Avassetimagegenerator alloc] initwithasset:asset];7Assetimagegenerator.appliespreferredtracktransform =YES;8Assetimagegenerator.aperturemode =Avassetimagegeneratoraperturemodeencodedpixels;9 TenCgimageref Thumbnailimageref =NULL; OneCftimeinterval Thumbnailimagetime =Time ; ANserror *thumbnailimagegenerationerror =Nil; -Thumbnailimageref = [Assetimagegenerator copycgimageattime:cmtimemake (Thumbnailimagetime, -) Actualtime:null error:&Thumbnailimagegenerationerror]; -  the     if(!thumbnailimageref) -Cximlog (@"Thumbnailimagegenerationerror%@", thumbnailimagegenerationerror); -  -UIImage *thumbnailimage = thumbnailimageref?[[UIImage alloc]initwithcgimage:thumbnailimageref]: nil; +     returnthumbnailimage; -}
