kickflip-ios-sdk's Issues

audio only 941 or 940 buffer size for iphone 6s. causing the video to get out of sync.

Hi,

Im using the iphone 6s and the audio from the internal mic works differently, it sends out smaller buffers which causing the video to get out of sync

What should I do in order to fix it, I know its should be somewhere here:

CMBlockBufferRef blockBuffer = CMSampleBufferGetDataBuffer(sampleBuffer);
CFRetain(blockBuffer);
OSStatus status = CMBlockBufferGetDataPointer(blockBuffer, 0, NULL, &_pcmBufferSize, &_pcmBuffer);
NSError *error = nil;
if (status != kCMBlockBufferNoErr) {
error = [NSError errorWithDomain:NSOSStatusErrorDomain code:status userInfo:nil];
}
NSLog(@"PCM Buffer Size: %zu", _pcmBufferSize);

    memset(_aacBuffer, 0, _aacBufferSize);
    AudioBufferList outAudioBufferList = {0};
    outAudioBufferList.mNumberBuffers = 1;
    outAudioBufferList.mBuffers[0].mNumberChannels = 1;
    outAudioBufferList.mBuffers[0].mDataByteSize = _aacBufferSize;
    outAudioBufferList.mBuffers[0].mData = _aacBuffer;
    AudioStreamPacketDescription *outPacketDescription = NULL;
    UInt32 ioOutputDataPacketSize = 1;
    status = AudioConverterFillComplexBuffer(_audioConverter, inInputDataProc, (__bridge void *)(self), &ioOutputDataPacketSize, &outAudioBufferList, outPacketDescription);
    NSLog(@"ioOutputDataPacketSize: %d", (unsigned int)ioOutputDataPacketSize);
    CMTime pts = CMSampleBufferGetPresentationTimeStamp(sampleBuffer);

Problems getting this to build

Hello! I'm trying to get your iOS SDK example to build and I'm having issues.

The first is that, after cloning the repo and running git submodule update --init in the repo, I come across two errors:

import "KFSecrets.h" <- not found

import "KFHLSUploader.h" <- not found

Could you please add templates for the KFSecrets.h and the KFHLSUploader.h as well? Really looking forward to trying this out!

UPDATE:

After commenting out the KFSecrets.h line and finding the KFHLSUploader.h by downloading the repo, not cloning it (weird issue), I was able to realize that I needed to do a few more submodule updating to get the files I needed. Now, I'm only down one file. I can't find the following files:

In FFFile.h, #import "libavformat/avformat.h" <- not found

FFmpeg legal issue

First of all kickflip is a terrific work.. hats off to the developer .But one question is bothering me. That is kickflip have used ffmpeg wrapper which means ffmpeg library has been used. But FFmpeg is LGPL compliant which is against app store .. So isn't it that if my ios app ...if it uses kickflip may face future problem in due to ffmpeg Lgpl licesce..

An answer would be appreciated

AFNetworking 2.0 support

HI ,

In kickflip.io it reports missing files and classes because they were removed in AFNetworking 2.0. Can you guys update the SDk to work with latest AFNetworking version please or should i ?

eg "AFJSONRequestOperation.h" is not found
"AFHTTPClient' not found etc etc.

How i switch the camera front and back

How i switch the camera front and back ?

libavcodec.a static library clash with gstreamer libavcode.a

issue:
after install kickflip sdk to a gstreamer based project, gstreamer links to the kickflip version of libavcode through pods, and it causes conflicts and random crashes.

suggested change:
not using precompiled static library or at least Can we change the pre-compiled FFmpeg lib included in the kickflip dependence with a prefix like KFlibavcodec ?
This post is illustrates this issue pretty well: http://landonf.bikemonkey.org/code/ios/Radar_15800975_iOS_Frameworks.20140112.html

#import "librtmp/log.h" file not found

I am trying to implement kick flip IOS SDK in my project but after setup pod file its show me error message

<Bolts/BFTask.h> file not found

after searching on internet i found replace
pod 'Kickflip'

pod 'Kickflip', :git => 'https://github.com/zummenix/kickflip-ios-sdk'

but after doing that it give me new error message

import "librtmp/log.h" file not found

so please tell me what should do to solve this problem?

stream url taking to long to response

After I present the broadcast controller with:

    Kickflip.presentBroadcasterFromViewController(self,
            ready: { stream in
                if ((stream.streamURL) != nil){
                   print(stream.streamURL)
                }
            }, completion:{ success, error in
                if (!success) {
                    print("Error setting up stream: %@", error);
                } else {
                    print("Done broadcasting");
                }
        })

First I'm getting this

codec not found: h264
[mpegts @ 0x17c38600] muxrate VBR, pcr every 3 pkts, sdt every 200, pat/pmt every 40 pkts

and then it takes up to 14 seconds to get the streaming URL. Am I missing something or should I do something different because 14 seconds is to long to get the streaming URL ? (I'm using iPhone 4S and and iPad to test it)

Thank you in advance.

kickflip.io is down

I don't know if there is another way to get in touch with the administrator of the servers... but the service is down

Live Streaming

Good morning. Having a problem while using your SDK. I have about 30+ seconds of delay with buffering label. Could I make this process faster? And one more question - will I see the newest recorded frames while watching live streaming when I play video from url provided by your sdk, or I will start from the start of the video?

kickflip.io is down?

Some of segment dose not upload and dose not generate proper index file .m3u8

Some of segment(.ts) dose not upload and dose not generate proper index file .m3u8

I have uploaded many streams some streams dose not upload proper, and also missing some segment in the index file(m3u8).

Signature not match

Message = "The request signature we calculated does not match the signature you provided. Check your key and signing method.";

I am getting this issue while calling [self.s3 putObject:uploadRequest].

I am not getting why signature is not match .

Please help me with this.

Please reply to support emails :(

Guys , i have been sending many emails to support , we are working on an app and kickflip.io is best fit for us. But unfortunalty we cant start working on it untill you response to our emails. having no response also gives hint for an un certain future about support when we go live , we cant spend millions of dollars and stay in dark.

Experiencing Problems

We are experimenting with kickflip. But every time we load the stream, it seems to be starting from the beginning of the stream, so it's not really "live". What are we doing wrong or did we miss the concept of kickflip?
And also we are having problems to start a stream from time to time , maybe lowering the packet size for the uploads will be a solution but even there are docs , we could not figure out what to do.
And one final thing , we read all the issues here and many people asked for that but could not find the solution for :
"codec not found: h264
[mpegts @ 0x13006be00] muxrate VBR, pcr every 3 pkts, sdt every 200, pat/pmt every 40 pkts"

We are working on an app for iOS , testing on iPhone 6 plus and did the whole pod updates also cleaned xCode Derived data but still the same.

Video recorded with Kickflip example doesn´t work

Hi. I am running the example proyect to iOS and i have experimented two problems:

The block method to get the stream URL is never called.

Code:
[Kickflip presentBroadcasterFromViewController:self ready:^(KFStream stream) {
if (stream.streamURL) {
DDLogInfo(@"Stream is ready at URL: %@", stream.streamURL);
}
} completion:^(BOOL success, NSError error){
if (!success) {
DDLogError(@"Error setting up stream: %@", error);
} else {
DDLogInfo(@"Done broadcasting");
}
}];

When I try reproduce the videos recorded with the app, in the web page, appears a "Buffering" message, but the video is never reproduce.

Thanks.

AVAssetWriter appendSampleBuffer failure

hi, i use kickflip to record video, but sometimes when i start a recording, the terminal says: "writer error, the operation couldn't be completed", and i think it is the avassetwriter problem, in VideoEncoder.m file, _writerInput appendSampleBuffer method sometimes fails, and this problem reproduces easily, about ten percent of all recordings.
the worst thing is , when this situation occurs, i cannot solve this by restarting another recording, the following recording will always failure. i searched the net and couldn't find a answer, plz help, thanks in advance..
the _writer.error message is "Error Domain=AVFoundationErrorDomain Code=-11800, this operation couldn't be completed. OSStatus error -12983, NSLocalizedFailureReason=Unknown Error"

Cannot play video after create by ios sdk

I use [Kickflip presentBroadcasterFromViewController:ready:completion:] to create Stream. After record finish, completion block has been call with success = YES, error = nil.

But I cannot play that video, other video has been upload by android sdk play ok.

Video orientation

Anyone know how to change the orientation on the video, this video https://kickflip.io/67ef4f00-06df-4f1c-a84e-be71e877cf7d/ was recorded "AVCaptureVideoOrientationPortrait" but when i play the video is from side, any idea?

the cpu use is huge

hi:

i am still testing this sdk, and i found that the cpu using is almost 80% on my iphone5.

any plan to profile that?

Can't install using Cocoapods

Getting the following issue: The 'Pods' target has transitive dependencies that include static binaries

Getting crash on long length video.

Apps getting crash while recording long length session. Its happen while your session is approx. more then 30 min or more.

Memory leak in KFH264Encoder

when set _recorder to nil, the KFH264Encoder member is not being released since there is a reference to it.
When instantiating the KFH264Encoder object (in KFH264Encoder::initWithBitrate) you pass a completion handler to _encoder.

my (simple) solution was to add a "shutdown" method to KFH264Encoder and remove the references to the completion handlers.

-(void) shutdown
{
[_encoder encodeWithBlock:nil onParams:nil];
}
call it before set _h264Encoder = nil;

this solution will free the encoder object

Error starting stream, fetch an active user first - kKFAPIClientErrorDomain

Hi,

We're a paying customer and have launched an app in de appstore with kickflip in it. But although we had issues with the webservice last month, it seems that it has returned again.

If we want to start a livestream, we get this error: "Error starting stream: Fetch an active user first."
And after that "kKFAPIClientErrorDomain error 105". We haven't changed our code, but it's not working anymore.
This afternoon I also tried it with the new v1.3 kickflip sdk, but we're experiencing the same issue. Can you please look into this issue?

Please update the mantle 2.0

Missing chunks in video

Hi,

With the latest sdk (v1.3) we're still experimenting issues with missing parts of the video. When you record a livestream, and later on you'll view the video, there are parts missing in the video. The issue was already there for a while, but still not solved in this version.

See for example: https://kickflip.io/67841435-5319-4d65-ba39-55e00b00133c/
Sometimes it's working fine, sometimes not, about 50% I think.

Perhaps related to: Kickflip/kickflip-ios-example#6 ?

BFTask error.

After installing new version via pods we are getting attached error. Please help us.

Sometimes streaming doesn't work

We are considering usage of your service in our project. But sometimes streaming doesn't work even on your site in the dashboard section. Is it due to Free Trial Plan?

Signature Match issue.

We are getting signature match issue for amazon s3. Would you please guide us?

And my custom captureGenerateVideoOutput:CMSampleBufferRef method that I integrated in my Recorder class. that is pretty much a clone of the KFRecorder.h/m

-(void) captureGenerateVideoOutput:(CMSampleBufferRef)sampleBuffer{
    if (!_hasScreenshot) {
        UIImage *image = [self imageFromSampleBuffer:sampleBuffer];
        NSString *path = [self.hlsWriter.directoryPath stringByAppendingPathComponent:@"thumb.jpg"];
        NSData *imageData = UIImageJPEGRepresentation(image, 0.7);
        [imageData writeToFile:path atomically:NO];
        _hasScreenshot = YES;
    }
    if(_h264Encoder)
        [_h264Encoder encodeSampleBuffer:sampleBuffer];

}

any thought on rtmp publish?

Any plans for a swift SDK ?

Curious.

Dose not start background process of hls upload, when you got unpredictable crash or remove from background by the user.

Dose not start background process of hls upload, when you got unpredictable crash or remove from background by the user. you're recording stream no more longer available in this scenario.

Attempt to use RTMP instead of HLS

I'm trying to replace hls with rtmp in the sdk. Just to test, I change outputPath in setupOutputPath function in KFHLSWriter to my rtmp end point, change output format to flv and add bitstream filter aac_adtsoasc:

- (void) setupOutputFile {
//    NSString *outputPath = [_directoryPath stringByAppendingPathComponent:@"index.m3u8"];
    NSString *outputPath = @"rtmp://<rtmp-endpoint>/live/test";

    _outputFile = [[FFOutputFile alloc] initWithPath:outputPath options:@{kFFmpegOutputFormatKey: @"flv"}];

    FFBitstreamFilter *bitstreamFilter = [[FFBitstreamFilter alloc] initWithFilterName:@"h264_mp4toannexb"];
    FFBitstreamFilter *bitstreamFilterAAC = [[FFBitstreamFilter alloc] initWithFilterName:@"aac_adtstoasc"];
    [_outputFile addBitstreamFilter:bitstreamFilter];
    [_outputFile addBitstreamFilterAudio:bitstreamFilterAAC];
}

(I added addBitstreamFilterAudio: function in FFmpegWrapper so the filter aac_adtstoasc will be added only if codec_id is AV_CODEC_ID_AAC).

That's all I can do for now, the app can run without problem. But if I check the output file with ffmpeg:

ffmpeg -i test.flv

then here's the output:

[flv @ 0x7fe764001000] Could not find codec parameters for stream 1 (Audio: none, 0 channels): unknown codec
Consider increasing the value for the 'analyzeduration' and 'probesize' options
Input #0, flv, from 'test.flv':

    Stream #0:1: Audio: none, 0 channels

There's something wrong when encoding audio stream. Any ideas how to fix this?

Recorded video stops not at start and end

Sometimes the recording starts the recorded video after more than 60 seconds (both on web and on device) and sometimes it also ends earlier (it misses the last 20 or 5 seconds). When recording via the iOS SDK. Othertimes it works well and only misses the first second (not a big issue). Tested with some recordings of 1 or 2 minute(s).

Is this a SDK issue, or something from the encoder settings? And can anything be done to fix this?

Handle 'applicationDidEnterBackground' gracefully

User has broken streams due to this issue. Steps to reproduce:

Start streaming, wait some time;
Tap Home button of the device (the app becomes inactive), wait some time;
Tap on icon of the app (the app becomes active);
User sees that streaming continues, but there is an error writer error Operation Interrupted in the console.

KickFlip SDK as an iOS Framework?

Is there anyway you could provide the SDK as an iOS framework? I would like to add the SDK to my own project without having to use CocoaPods and the example application.

Video orientation

Codec not found: h264

At startup of broadcasting in the Example app this string appears in the log:
Codec not found: h264
also obtained chunks (indexX.ts) are not always played players due to missing 'moov' atom.

streamState must either map to a JSON key path or a JSON array of key paths, got: null.

We are getting following attached error. Would please tell me where we have to set AWS S3 Credentials?

Reduce latency of H.264 encoder

I use codecs to encode a stream video , but i found some frame output are very slow. It should be more then 80ms even 200ms . It's not for all frame .
I think may be the result of file locking .
Any good Suggestions

<Bolts/BFTask.h> file not found

I installed dependencies via cocoa pods but when I compiled the project there is an error in the files KFAWSCredentialsProvider.h and in the file KFAWSCredentialsProvider.m

In KFAWSCredentialsProvider.m the error is in the line:

import <Bolts/BFTask.h>

Bolts/BFTask.h file not found

In KFAWSCredentialsProvider.h the error is in the line:

(BFTask *)refresh;
Expected a type

It works before but I update cocoa because Kickflip not work in my mobile with the version 1.2 but now not compiled with the version 1.3

feature question

I send the mail to [email protected]

but cant get any reply !

Kickflip Can provide the same function just periscope or meerkat ?

(i mean We mainly need to use the iOS SDK to stream the camera video up to your platform and use your SDK to play the stream down to one or more clients, this is the first thing we need to try it now.)

2.how many people can upload streaming at same time ? have any restriction ?

3.(when user registered on our platform, we have to create account for the user and allow them to stream their own videos up to your platform)

Whether can manage user by our backend server ?

charge by app number or broadcast number ?
where the data will be storage ? we need to use AWS , or upload to your cloud ?
transfer data will have extra charge ?

6.can provide record feature ? , let people can see video later

7.what is average delay time from broadcaster to people watch ?

Update podspec for AWSS3 to 2.1.2

Currently doesn't build, or update framework to use AWSS3 2.2

Is this project dead?

Trial didn't work. Many problems with the demo app. Code hasn't being touched for a while.
