AVPlayers は HLS を再生しますが、MP4 ビデオでクラッシュします。次の URL を使用しています。また、iOS 用の IMA SDK を使用して広告を再生しています。これは 1 番目の URL で完全に機能しますが、広告を再生せずに 2 番目の URL でアプリがクラッシュします。

iOSバージョンを使用：10.1

URLにスペースがあったので、誰かからの次の方法を使用してURLをエンコードしました。

- (NSString *) URLEncodedString_ch:(NSString*) str {
NSMutableString * output = [NSMutableString string];
const unsigned char * source = (const unsigned char *)[str UTF8String];
int sourceLen = strlen((const char *)source);
for (int i = 0; i < sourceLen; ++i) {
    const unsigned char thisChar = source[i];
    if (thisChar == ' '){
        [output appendString:@"+"];
    } else if (thisChar == '.' || thisChar == '-' || thisChar == '_' || thisChar == '~' ||
               (thisChar >= 'a' && thisChar <= 'z') ||
               (thisChar >= 'A' && thisChar <= 'Z') ||
               (thisChar >= '0' && thisChar <= '9')) {
        [output appendFormat:@"%c", thisChar];
    } else {
        [output appendFormat:@"%%%02X", thisChar];
    }
}
return output;

}
