I am using compiled version of rtmp-dump from github in my iOS project. Following is the code to connect to the server.
rtmp = RTMP_Alloc();
RTMP_Init(rtmp);
NSString *url = #"rtmp://192.168.0.119:1935/red5/sw231/";
char *strUrl = (char *)[url cStringUsingEncoding:NSASCIIStringEncoding];
RTMP_SetupURL(rtmp, strUrl);
RTMP_Connect(rtmp, NULL);
Since the proper documentation of rtmp-dump OR lib-rtmp is not available I want to know the methods that I can use for the following functionalities.
I want to send an array of values while connecting. My query is by what method of rtmp-dump can I send values to the server when connecting?
How can I call certain methods of the server and pass parameters to the server?
How can I receive response from the server? As well as how can I implement client-side method invocation through rtmp-dump?
How can I explicitly provide the name of the stream which I want to play or listen to after connecting?
By using RTMP_Close(), will I be able to disconnect the connection?
I know this post was asked 12 months ago but this may be usefull.
Download this and see the examples of usage of librtmp. I don't know why this library has no documentation but following that examples can help you a bit.

To start, here is my code:
var buffer = malloc(interop.sizeof(interop.types.UTF8CString));
var fillBuffer = mac.getBytes(buffer);
var bytes = new interop.Reference(interop.types.UTF8CString, buffer);
var hexMac = bytes[0];
The variable 'Mac' is an NSData objected retrieved from CoreBluetooth. It is the scan response from a BLE device, which contains the peripheral's MAC address (00:0b:57:a2:fb:a0).
This problem is linked to THIS question I had posted earlier.
The solution provided is great; however, I cannot seem to implement this in nativescript :
(instancetype)stringWithFormat:(NSString *)format, ...;
Intellisense tells me the method doesnt exist on type NSString.
Due to that issue, I decided to go another route (as you can tell). I am filling a buffer with the bytes of the MAC address. In the code above, bytes[0] equates to 0xb57a2fba0.
I am now trying to convert that (which is an interop.Reference) into a string that I can store on the back-end (preferably in the xx:xx:xx:xx:xx format).
I have been at this all weekend, and cannot seem to find a solution. I even broke down objc!foundation.d.ts to figure out if stringWithFormat was supported, to no avail.
The nativescript community slack was unable to provide a resolution as well.
Please help if you can!
I don't know anything about NativeScript at all, but given the other code you wrote, I assume you're calling +alloc first, and so mean to use -initWithFormat: (an instance method that initializes) rather than +stringWithFormat: (a class method which handles allocation and initialization).
How can I get notifications count of another app into my app by using SpringboardServices and SBSPushStore?
I'm trying to show notification count taken from whatsapp into my app so I was searching around and one thing is for sure that it is possible but I didn't find any approbate way on how to do it.Here is the question which answers it but I didn't get it. How to do it? Can someone please share the step by step procedure.
Based on the question I was able to find the code which can actually lock you iphone using SpringboardServices but I don't know how to use it for SBSPushStore?
void *SpringBoardServices = dlopen("/System/Library/PrivateFrameworks/SpringBoardServices.framework/SpringBoardServices", RTLD_LAZY);
NSParameterAssert(SpringBoardServices);
mach_port_t (*SBSSpringBoardServerPort)() = dlsym(SpringBoardServices, "SBSSpringBoardServerPort");
NSParameterAssert(SBSSpringBoardServerPort);
SpringBoardServicesReturn (*SBSLockDevice)(mach_port_t port) = dlsym(SpringBoardServices, "SBSLockDevice");
NSParameterAssert(SBSLockDevice);
mach_port_t sbsMachPort = SBSSpringBoardServerPort();
SBSLockDevice(sbsMachPort);
dlclose(SpringBoardServices);
The answer to that linked question you commented on implies that you don't need any framework, as long as your device is jailbroken.
You simply load the plist file located at /var/mobile/Library/SpringBoard/applicationState.plist. The format of that answer is a bit broken, but I assume the > are meant as indicators to explain the inner structure of the file (i.e. key values).
So from that I assume it's a dictionary, you can load it by
NSDictionary *plistFile = [NSDictionary dictionaryWithContentsOfFile:#"/var/mobile/Library/SpringBoard/applicationState.plist"];
NSDictionary *entryForYourApp = plistFile[#"com.app.identifier"]; // obviously you have to use the identifier of whatever app you wanna check
NSInteger badgeCount = entryForYourApp[#"SBApplicationBadgeKey"];
You probably want to inspect the file yourself first (so set a debug point) and make sure its structure is like I assumed, the types are correct and so forth (not to mention it exists, Apple sometimes changes stuff like that and the other question is already several years old).
In general be aware that you can only do that, as said, on a jailbroken device. Otherwise your application simply doesn't have reading access to the path /var/mobile/Library/SpringBoard/applicationState.plist. Or to anything outside its sandbox, for that matter.
What I want to implement is as follow:
A-app (calling app) : request the return value of a-string sent as parameter : request(a-string) -> b-string.
B-app (plug-in installed separately by me or others, it plays the role of dictionary or database ) : search a-string from database and return the result (b-string).
With successful experiences of plug-in on android and with Apple's confident rhetoric of plug-in, I thought plug-in, of course, run on iOS. After a lot of hard work, however, I finally found out:
* Note : The creation and use of loadable bundles is not supported in iOS.*
Nonetheless, not giving up, I finally made it with custom URl and pasteboard:
A-app : write a-string and false state to pasteboard & call B-app via custom URL.
B-app : viewDidLoad runs following func and thereafter exit program ; func { read pasteboard and search from database & write the result(b-string) and true state to pasteboard }
A-app : while-loop detects whether state is false or true. if true, catch b-string from pasteboard.
Anyway it works but it's too long thus almost useless. Do you have any idea for better solutions? Why doesn't Apple allow plug-in for iOS? Any responses are welcome. Thank you.
I can't answer why Apple doesn't allow plug-ins, but I can offer some advice on what you're trying to achieve.
The common pattern for sending data back to your application is to implement a callback url, so the A-app would also implement a custom URI and add that to the uri sent to B-app.
B-app would then process the uri as you have already implemented, but then instead of exiting, it simply sends the data you requested in the uri passed to it.
See http://x-callback-url.com for more details and example implementations.
Currently, in my AppDelegate, I have an instance variable declared for GNConfig that is set up with all properties I would like to receive.
This instance of GNconfig is used by any class that makes a gracenote request.
The requests I am using are recognition from an audio stream, recognition by local file and a text search which populates an array. The array is then used for track lookups by id for the corresponding array item.
I am able to get all the content I need, except for track and album link data (always returns null).
I have tried plenty of different suggestions and guides with no luck.
Could somebody please help me out? This data is essential to my app and my app is pretty much complete except for this big obstacle.
Thanks in advance.
** edit **
This is in my appDelegate:
_gnConfig = [GNConfig init:#"XXXXXXX-XXXXXXXXXXXXXXXXXXXXXXX"];
[_gnConfig setProperty:#"content.coverArt" value:#"1"];
[_gnConfig setProperty:#"content.coverArt.sizePreference" value:#"LARGE"];
[_gnConfig setProperty:#"content.allowFullResponse" value:#"1"];
I have this in one of my class methods:
NSURL *filePath = [item valueForProperty:MPMediaItemPropertyAssetURL];
[GNOperations recognizeMIDFileFromFile:self config:[[AppDelegate sharedDelegate] gnConfig] fileUrl:filePath];
In the delegate method I have:
gracenoteResponseItem = [result bestResponse];
NSLog("%#", [gracenoteResponseItem trackLinkData]);
Some tracks may not have link data available.
Also if you are doing a local lookup then you will have to set this config option:
[publicProperties setObject:#“1"forKey:#"content.allowfullresponse"];
Unless you have explicitly had your client ID entitled for Link IDs (aka 'external' or '3rd party' IDs), you won't get any in your responses.
By default, Gracenote Open Developer client IDs aren't entitled for any external IDs. You need to coordinate with Gracenote to entitle your client ID to start receiving the desired IDs.
How do I use the google translate API with iOS 6.0? I have tried googling the documentation and tried to research it, but I can't find anything that is updated since google made the api to be no longer free.
The only thing I have been able to find was this, but it didn't really help much because I need to use the api key that I have, but I have no idea how to.

This seems up to date: https://developers.google.com/translate/v2/getting_started
(completely meta: Oops! Your answer couldn't be submitted because:

Yes, it is. Once you get your Google key, just plug it into FGTranslator. Note, generate a "server" key, since the Google Translate API does not currently support iOS keys.
It's just a one-line call to the translate function after that.
FGTranslator *translator = [[FGTranslator alloc] initWithGoogleAPIKey:#"your_google_key"];
[translator translateText:#"Bonjour!"
completion:^(NSError *error, NSString *translated, NSString *sourceLanguage)
{
NSLog(#"translated from %#: %#", sourceLanguage, translated);
}];
