@matrog: tried with your libTVVLCkit.a file but get the same error:

"libTVVLCKit.a(VLCMedia.o)' was built without full bitcode."

Do you get the same result when you do an Archive?

Finally got it archived with bitcode enabled!
I post this info because it could be helpful for others.
I looked into the build scripts and found that the correct flag is indeed set, "-fembed-bitcode". No reason to patch or modify anything.
Then I found this post:
https://forum.videolan.org/viewtopic.php?f=36&t=128654

So I followed that advice and removed libTVVLCkit.a and instead imported the whole MobileVLCKit project into my app and linked that. BOOM!

---ISSUE SOLVED SEE END OF MESSAGE
Hi everyone.

I am working onto a Swift Project and I can't get TVVLCKit working. I ve done all the steps from Matrog and the MobileVLCKit compiled.

First I add to

Code: Select all

import UIKit/UIKit.h
into VLCMediaPlayer header file otherwise the compiler complains about Unknown class UIImage afterwards

I use the command:

Code: Select all

lipo -create Debug-appletvos/libTVVLCKit.a Debug-appletvsimulator/libTVVLCKit.a -o libTVVLCKit.a
Everything works fine the libTVVLCKit.a is created.

Here is where it gets tricky.
I import libTVVLCKit.a into my Swift project as well as the headers files created into one of the build folder say "Debug-appletvos/TVVLCKit/*.h"
In order to use this library in Swift I did a bridge file which basically links every header files from TVVLCKit so that it can be used in Swift.

Code: Select all

#import "VLCMedia.h" #import "VLCMediaDiscoverer.h" #import "VLCMediaList.h" #import "VLCMediaPlayer.h" #import "VLCMediaListPlayer.h" #import "VLCMediaThumbnailer.h" #import "VLCTime.h"
The imports are working since I can now use VLCMediaPlayer into my code with auto completion.

However when I try to build the project I have the following error:

Code: Select all

ld: library not found for -lTVVLCKit clang: error: linker command failed with exit code 1 (use -v to see invocation)
This error disappear when I copy and paste de TVVLCKit.a created with the previous command into my project folder

Then 130 new errors appears when compiling:
Image

Is anyone experiencing the same kind of issue ?

I also tried the Workspace thing but I m not sure I did the workspace properly. Would be great to have more detailed step by step procedure to make Workspace with your project and TVVLCKit.

Thanks in advance for your help !

Vincent.

--EDIT

I think I did manage to have the Workspace working. Linking with library is much easier now since I use the Workspace location. But I still have the errors.

I think the TVVLCKit.a it uses is the one for AppleTVOS not the simulator. Does TVVLCKit only works on real device ?

--EDIT Solved
Add libc++ and libiconv to my project. It s compiling successfully !

Hello, I followed these steps:
I did the following
1. downloaded zip file
2.

Code: Select all

./buildMobileVLCKit.sh -t
3.

Code: Select all

./buildMobileVLCKit.sh -t -s
4. Opened MobileVLCKit.xcodeproj in Xcode, switched to TVVLCKit and built successfully for device.
5. built successfully for device simulator
6. Open terminal, go to the folder where Xcode produced libTVVLCKit.a file (for me /Users/xxxxx/Library/Developer/Xcode/DerivedData/MobileVLCKit-cajvscpvucjubqcjljaxxzklzcas/Build/Products/)
7. Run the following to have a static lib for tv and simu

Code: Select all

lipo -create Debug-appletvos/libTVVLCKit.a Debug-appletvsimulator/libTVVLCKit.a -o libTVVLCKit.a
8. Add the new libTVVLCKit.a to your project
at 2nd and 3rd step have generated lots of warnings, but at the end it has been compiled.
Followed the next steps without any errors or warnings.
I got libTVVLCKit.a created by lipo and TVVLCKit's .h files from Build/Products/ and imported it into new tvOS project. I linked libTTVLCKit.a, libc++.tbd and libiconv.tbd.
I tried to this code:

Code: Select all

#import "ViewController.h" #import <TVVLCKit/TVVLCKit.h> @interface ViewController () <VLCMediaPlayerDelegate> { VLCMediaPlayer *_mediaplayer; } @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. _mediaplayer = [[VLCMediaPlayer alloc] init]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
It doesn't compile. I have 51 warnings and 13 errors, here is log:
http://pastebin.com/i7AE39P0

(during building ./buildMobileVLCKit.sh -t terminal shows popup with missing JDK, could it be my problem? without it, after building I can build it without any errors in Xcode..)
Please help me with fix this problem, I spent three days without any success...


Edit:
I compiled tvOS with TVVLCKit successfully. I didn't import AVFoundation/AVKit into my project... ;/ Right now is working correctly ;)

Hello,

I just got the lib working with the bridging header.
But when I try to build my project I get the following error:

Code: Select all

​Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_VLCMedia", referenced from: type metadata accessor for __ObjC.VLCMedia in ChannelViewController.o "_OBJC_CLASS_$_VLCMediaPlayer", referenced from: type metadata accessor for __ObjC.VLCMediaPlayer in ChannelViewController.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have all the lib files, I'm linking to libiconv and libc++.

Can anyone help me?
What am I doing wrong? :/

I'm trying to build libTVVLCKit but I'm seeing a different issue then everyone else. After I run './buildMobileVLCKit.sh -t' and open the Xcode project both "vlc-plugins-iPhone.h" and "vlc-plugins-AppleTV.h" are missing. This obviously leads to a compiler failure since VLCLibrary.m includes them. Am I missing a step somewhere? I was not able to find either of these files in the git project.

Just tried to compile again and I now have the same error :/
But in my case the iPhone and tvOS .h files are missing.

I have no idea what we are making wrong :/

Yes that is the exact same situation I have. Are those .h files suppose to come from somewhere else?

I ran the script "./buildMobileVLCKit.sh -t" and received the below output. This is the second time through so it didn't need to download all the remote files. I'm concerned with the error at the end. Could that be the issue?

Can someone post an sucessfully compiled version for the TV? Of course only if this is allowed.
Would be so awesome!

Unfortunately, when I try to compile TVVLCKit not find the file vlc - plugins- AppleTV.h ????
The only solution was to use TVVLCKit.a of matrog but I get the bitcode error.
Can you give me a compiled version with correct bitcode?

Thanks

I try build with -t then with -t -s then open xCode try to build but file.h were missing I try to build again with -v -t didnot work then try again with -t and it worked !

Another minor issues I experimented is the following one:
Je xcode project alone compile in xcode but when it is included into my workspace of my application and configured the building settings for tvOS i got an error in VLCMediaPlayer.h saying: unknown type name "UIImage". I just added import UIKit
like such:

Code: Select all

#import "UIKit/UIKit.h"
at the beginning of the .h file and it works. Just wanted to let you know about this issue.

In addition, I also had to add to my project the following things:
TVVLCKit.h
libTVVLCKit.a
libc++.tdb
libiconv.tdb

and this is it :) Hope this help people :D
