The VideoLAN Forums

Hello,
I'm working on a project to view on iPhone/iPad videos that are stored on some local network disks using http interface (I'm using libVLC and MobileVLCKit from source code of VLC for iPad) !
Thanks to the help of Pierre, I managed to make some modifications to pass needed cookies from authentication (will post the patch to vlc-devel soon) and now all is working well using http, but when I switch to https, it's not working anymore

I think that it may be related to the fact that my server is using an untrusted server certificate, but I'm not an expert and I have no idea of where to start ...
Here is the verbose log in case someone could confirm the origin of the problem :

Of course everything is working well when using my safari browser to get the file (but it tell me that the certificate is untrusted)
Once everything will be sorted out and cleaned, I'll post the source code of my application
Thanks,
Sylver

You need to provision the appropriate certificate as trusted on the device. I have no clue how that's done on iPad.

Thanks Rémi for your answer ! I've seen in code headers that you are the one who coded the TLS part

You can provision the iPhone and the iPad with the same tool (iPhone configuration utility), but it's quite a complicated thing for most people !

Using standard iPhone NSURLRequest class, I found the way to accept untrusted certificates, and I'd like to be able to do the same with libVLC ! But I guess that it would require some parts of the protocol that is not implemented ? I know nothing about TLS protocol, but if someone could point a document explaining in a simple way what is needed in this case, I could try to hack the code ...

look at the gnutls.c code then.
