replace https://172.16.2.240:8001 with MYURL
replace path?querystring with FILEPATH

Hello,
As title, I always fail when I use mobileVLCKit iOS2.8, master which is build from source code. I also try mobileVLCKit iOS2.7 and moblieVLCKit stable 2.2.2 which are get from cocoapods and that are fail, either.
Only mobileVLCKit stable 2.2.2 will pop an alertView to ask me if I want to accept self signed certificate or not, but it will pop another alertView to say that It can't be played.
the other three will say "cannot access MyUrl" without popping an alertView to ask me if I want to accept self signed certificate.
above of four mobileVLCKit can play mkv from http.

When I use VLC for iOS(ver2.7. first time, the alertView will pop out and ask me if I can accept self signed certificate or not. If I choose "Accept" , the video will be played. Strangely, it will fail when I want to play from same source twice, maybe it is another bug.
I also try VLC on mac , and it always play successfully after accept the self signed certificate.

//below is error message when I use mobileVLCKit iOS 2.8

Sorry about my poor English, and thanks for your reading!
I have been sucked by this problem for few month QQ~

Update libVLC.

The only version i get it working is 2.7 branch but the question (that don't appear in this 2.7 version) has a bug. The result is never used to trust the cetificate.
Answer var is not good. Just bypass this piece of code in securetransport.c around line 326. Remove the if line that check for answer to force it like a always YES.

Version 3.0pre2 force close with this hack because of some closing bug that is fixed by later commit.
Version 3.0pre3 display 1 picture and say buffering forever but is just stuck somewhere.
Version 2.7 is the only that works.
Version 2.8 not tested.

If you need some help about the last compilation step, here is a link:
