AVPlayer воспроизводит HLS, но падает с видео MP4

Question

AVPlayers воспроизводит HLS, но падает с видео MP4. Я использую следующие URL-адреса; Я также использую IMA SDK для iOS для воспроизведения рекламы, которая отлично работает с 1-м URL-адресом, но приложение выходит из строя со вторым, не воспроизводя объявление.

с использованием IOS версии: 10,1

//NSString *const kTestAppContentUrl_MP4 = @"http://50.7.149.90:1935/pitvlive/ptvsportsnew3.stream/playlist.m3u8"; 

NSString *const kTestAppContentUrl_MP4 = @"http://50.7.149.74/vods/trailers/OK Jaanu-Official Trailer.mp4";

Answer 1

Существовал пространство в URL, поэтому я использовал следующий метод от кого-то для кодирования URL.

- (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; 

}
