	- (AVDictionary*) createAVFormatContextOptions: (NSDictionary*)dict
	{
	AVDictionary *options = NULL;
	for (NSString* keyString in dict) {
	av_dict_set(&options, [keyString UTF8String], [[dict objectForKey:keyString] UTF8String], 0);
	}
	return options;
	}
	- (void) updateAVFormatContextWithOptions: (AVDictionary**)options {
	if (_formatCtx)
	return;
	AVDictionary *tmp = NULL;
	if (options) {
	av_dict_copy(&tmp, *options, 0);
	}
	if (av_opt_set_dict(_formatCtx, &tmp) < 0) {
	av_dict_free(&tmp);
	}
	}
	- (void) someWhereElse
	{
	NSMutableString* cookieString = [NSMutableString stringWithString:@"Cookie: "];
	for (NSHTTPCookie* cookie in [NSHTTPCookieStorage sharedHTTPCookieStorage].cookies) {
	[cookieString appendFormat:@"%@=%@;", cookie.name, cookie.value];

	[cookieString appendString:@"\n"];
	NSDictionary* dict = [NSDictionary dictionaryWithObject:cookieString forKey: @"headers"];
	AVDictionary* options = [self createAVFormatContextOptions:dict];
	avformat_open_input(&amp;formatCtx, [path cStringUsingEncoding: NSUTF8StringEncoding], NULL, &amp;options)
