Setting User Agent for AVPlayer in DELPHI

Question

I am trying to set a User Agent for AvPlayer in Delphi based on the short code below:

NSMutableDictionary* * *headers = [NSMutableDictionary dictionary];
[headers setObject:@"YourHeader"forKey:@"User-Agent"];
self.urlAsset = [AVURLAsset URLAssetWithURL:self.videoURL options:@{@"AVURLAssetHTTPHeaderFieldsKey" : headers}];
self.playerItem = [AVPlayerItem playerItemWithAsset:self.urlAsset];
self.player = [AVPlayer playerWithPlayerItem:self.playerItem];

I am having trouble with this part:

options:@{@"AVURLAssetHTTPHeaderFieldsKey" : headers}

I have declared headers as NSMutableDictionary and setobject with the necessary fields, but how should I assign that to the key AVURLAssetHTTPHeaderFieldsKey?

I am using ALVideoPlayer from Alcinoe library and I need to set user agent there.

Answer 1

It appears to be doing the equivalent of this:

uses
  Macapi.Foundation, Macapi.Helpers, Macapi.AVFoundation;

var
  LDictionary: Pointer;
  LOptions: NSDictionary;
  LURLAsset: AVURLAsset;
  LVideoURL: NSURL;
begin
  // Make sure you initialize LVideoURL with whatever value it is expecting
  LDictionary := TNSDictionary.OCClass.dictionaryWithObject(StringToID('YourHeader'), StringToID('User-Agent'));
  LOptions := TNSDictionary.Wrap(TNSDictionary.OCClass.dictionaryWithObject(LDictionary, StringToID('AVURLAssetHTTPHeaderFieldsKey')));
  LURLAsset := TAVURLAsset.OCClass.URLAssetWithURL(LVideoURL, LOptions);
  // etc
end;
