GCKMediaInformation streamDuration = NSInterval.infinity throw NSInvalid Argument for JSON infinity value #475

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
// Trying to send MP4 stream with moof packets, my context but not related to 
issue.
var mediaInformation: GCKMediaInformation(
_,
streamType: GCKMediaStreamType.Live, // <- Valid parameter with streamDuration 
as infinity.
_,
streamDuration: NSTimeInterval.infinity, // <- This ultimately causes the issue.
_)

var mediaControlChannel:
mediaControlChannel.loadMedia(
mediaInformation,
_) // <- loadMedia tries to flatten streamDuration when set to infinity as JSON 
data. Causes exception.

What is the expected output? What do you see instead?
Expect success / No exception
Actual NSInvalidArgument Exception for JSON parse on infinity value.

What version of the product are you using? On what operating system?
Googlecast SDK 2.5.1
Yosemite OSX / Xcode simulator / iOS 8.1.2

Please provide any additional information below.
The document below (specifically states the above parameters) are correct:

The SDK docs indicate that you should use INFINITY (from math.h), which is a 
valid (but very large) double value. I suspect that Swift's 
NSTimeInterval.infinity is some other, special value that is not a valid value 
for a double.

Thank you for responding so soon. I have just tried to use the INFINITY from 
<math.h> and got the same error. (Below is the call stack). FYI NSTimeInterval 
is a alias for double. So NSTimeInterval.infinity is positive infinity. Unless 
I am mistaken it wouldn't make sense to me that there are multiple "values" for 
"infinity" for a double.

It would be probably helpful if I gave you the next three items in the stack as 
well...

I wanted to ensure it wasn't my code generating this error. So I modified the 
Obj-C iOS HelloVideoGoogleCast demo source provided by Google, with the 
following at Line 202 on HGCVViewController.m. It generated the same error. 
(Captured below) 

    GCKMediaInformation *mediaInformation =
    [[GCKMediaInformation alloc] initWithContentID:
     @"http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
                                        streamType:GCKMediaStreamTypeLive
                                       contentType:@"video/mp4"
                                          metadata:metadata
                                    streamDuration:INFINITY
                                        customData:nil];
