ios - AVPlayer performance - videos are flickering when scrolling a list fast -

-

i have list of 60 videos i'd display on list , play while user scrolling. unfortunately when i'm scrolling list fast, view totally unusable - video players flicker , there serious delay in scrolling (e.g. app freezes half second before rendering players , shows empty cells).

i tried using threads, didn't much. code snippet last tries looked way:

    cell.videosnippetplayerview!.hidden = true     dispatch_async(dispatch_get_global_queue(int(qos_class_user_interactive.value), 0)) {         cell.setvideo(urlstring, rowno: indexpath.row)         dispatch_async(dispatch_get_main_queue()) {             cell.videosnippetplayerview!.hidden = false         }     }

i used local video files (resources), there no delay caused network.

thanks!

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
