Publishing RTMP stream

#import "RtmpWrapper.h"

RtmpWrapper *rtmp = [[RtmpWrapper alloc] init];
BOOL ret = [rtmp rtmpOpenWithURL:@"YOUR RTMP PUBLISHING POINT" enableWrite:YES];
if (ret) {    
  NSData *video =
    [NSData dataWithContentsOfURL:[NSURL URLWithString:@"FLV VIDEO URL ON THE NET"]];
  NSLog(@"original video length: %d", [video length]);
  NSUInteger length = [video length];  
  NSUInteger chunkSize = 10 * 5120;
  NSUInteger offset = 0;
  
  // Let's split video to small chunks to publish to media server
  do {
    NSUInteger thisChunkSize = length - offset > chunkSize ? chunkSize : length - offset;
    NSData* chunk = [NSData dataWithBytesNoCopy:(char *)[video bytes] + offset
                                         length:thisChunkSize
                                   freeWhenDone:NO];
    offset += thisChunkSize;
    
    // Write new chunk to rtmp server
    NSLog(@"%d", [rtmp rtmpWrite:chunk]);
    sleep(1);
  } while (offset < length);
}

// Close rtmp connection and release class object
