Error broadcasting

[johanndiedrick]

When trying to broadcast with the default KFSecrets.h Client ID and Client Secret, I get this error:

2014-03-28 11:44:14.765 KFDemo[23974:60b] codec not found: h264
Parsing...
Parsed protocol: 0
Parsed host : live31.us-va.zencoder.io
Parsed app : live

This is after I hit the "Broadcast" button, then the "Start" button. The video comes up fine on the device.

After letting the app run for a few minutes, I get this error:

RTMP_Connect0, failed to connect socket. 60 (Operation timed out)
2014-03-28 11:45:29:968 KFDemo[23974:60b] Error preparing for writing: Error Domain=org.ffmpeg.FFmpeg Code=-1313558101 "Unknown error occurred" UserInfo=0x166a0090 {kFFmpegErrorCode=-1313558101, NSLocalizedDescription=Unknown error occurred}
(lldb)

Trying with my own Client ID and Secret, I get this error:

2014-03-28 11:49:02.936 KFDemo[23998:60b] codec not found: h264
Parsing...
Parsed protocol: 0
Parsed host : live31.us-va.zencoder.io
Parsed app : live

I get the same "Operation timed out" error with this as well after a minute or two.

Let me know what you think!

Ah this is still hard-coded to use RTMP mode which we are going to push back for the 1.1.x branch. I'll sort this out today!

[johanndiedrick]

Cool, thanks! Could you leave a comment when this is updated?

[chrisballinger]

Okay I've updated the SDK to fix that problem. It's still very rough around the edges, but the basic functionality is there. For now it might be best to use the submodule version of the podspec because I'm going to be doing some major development in the next two weeks before shipping our stable release.

[johanndiedrick]

Ok cool. How do I go about doing that? Should I download the repo?

[chrisballinger]

Fork the repo then try this:

$ git clone git@github.com:yourfork/kickflip-ios-example.git
$ cd kickflip-ios-example
$ git submodule update --init
$ pod repo update kickflip
$ pod
$ open Kickflip.xcworkspace

Thanks! I just tried a clean build (deleted my repo, forked it and then re-installed with the instructions above) but I get the following new errors:

fatal error: file '/Users/johanndiedrick/Documents/iOS/kickflip/kickflip-ios-example/Pods/Headers/FFmpeg-iOS/libavutil/time.h' has been modified since the precompiled header '/Users/johanndiedrick/Library/Developer/Xcode/DerivedData/ModuleCache/1K77AWNH1I9SN/CoreFoundation.pcm' was built

Huh thats weird, do any of these answers help?
http://stackoverflow.com/questions/18547895/cant-get-rid-of-apple-llvm-5-0-error

This might do the trick:

$ rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/*

[johanndiedrick]

Cool that worked. Xcode just needed a clean as well :)

Almost there! After hitting start, I get this message:

2014-03-28 19:12:28.046 KFDemo[24262:60b] codec not found: h264
[mpegts @ 0x173e9600] muxrate VBR, pcr every 3 pkts, sdt every 200, pat/pmt every 40 pkts

After a few seconds I get my stream URL link, but it doesn't seem to work. My browser tries to download a .m3u8 file...

Here's the output in the console:

2014-03-28 19:13:05:729 KFDemo[24262:60b] Stream is ready at URL: http://ch-test-29c466b1-cc55-49ad-8c91-9b4558d1af8e.s3.amazonaws.com/ch-test-29c466b1-cc55-49ad-8c91-9b4558d1af8e-nlz2or/bfe0ed3a-7634-41cb-8f73-5992a376ae96/index.m3u8

[johanndiedrick]

So I tried sharing the link via text message and I got the right URL:

https://api.kickflip.io/bfe0ed3a-7634-41cb-8f73-5992a376ae96

Chrome barked at me about being sure I wanted to visit the site (yellow warning screen, screenshot to come if I can get someone to replicate it):

The video looks ok, although it seems to be stuck in landscape mode (my phone is now oriented in portrait):

[chrisballinger]

Awesome, congrats on getting it to work!

We still need to get a proper SSL cert for that domain which is why you see
the warning in Chrome but we'll have that sorted out shortly.

For the time being we only support landscape mode because otherwise it
displays poorly on desktops and TVs, but that may be configurable down the
road.

As far as the direct m3u8 link, that one for playing in the default iOS
media player and should work if you open it in mobile Safari.

Thanks for trying it out, there is a lot of more functionality and
polish on the way. We're excited to see what you can build!

Updated the SDK quite a bit since you've last seen it, check it out!
