AVPlayer spielt HLS ab, stürzt aber mit MP4-Video ab

Question

AVPlayers spielt HLS ab, stürzt aber mit MP4-Video ab. Ich verwende die folgenden URLs; Ich benutze auch IMA SDK für iOS, um Anzeigen zu spielen, was perfekt mit der ersten URL funktioniert, aber die App stürzt mit der zweiten ab, ohne die Anzeige zu spielen.

mit iOS-Version: 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

Es gibt einen Raum in der URL ist, so habe ich die folgende Methode von jemandem die URL zu kodieren.

- (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; 

}
