Any way to filter images with SCFilter?

Hey guys.

I have everything working video wise. But I was wondering if, or maybe how, one can implement the snapchat like filtering of SCFilterGroup with an image, rather than a video.

Any help would be great.

Thanks

Is there a way which can custom size of video ?

I using SCViewController to record video but I don't know how to custom size of video ,ex 640x640

AVAudioSessionMediaServicesWereResetNotification

Hey there!

There is a problem when running the camera for the first time. I wasn't able to get any error messages from any of the delegate methods. So I tried listening to as many notification as possible to find out what's going on. For some reason, AVAudioSessionMediaServicesWereResetNotification posts up a notification. I worked around putting up some code to close and reopen the session in order to get it working. However, I still do not know what causes this.

Big bug

@rFlex
When I finished recording audio, back to the home page, again into the video recording, crash now，reason was
SCAudioVideoRecorderExample[4306:60b] *** -[SCCamera release]: message sent to deallocated instance 0x16de65a0

Can I use this to only capture Audio?

Hi,

I would like to use this library but the need in my app is only to capture the audio, not the video. Can I still use this library?

Thanks,
Varun

didBeginRecordSegment called after didEndRecordSegment

I thought "didBeginRecordSegment" was called when segment recording begins. It's actually called after "didEndRecordSegment".

SCAssetExportSession export throws exception when Audio is Enabled

Hi rFlex,
When the SCRecorder has audio enabled the SCAssetExportSession when exporting the video file with a filter on top of it crashes when it begins to read in the data. Have you seen this?
Thanks

Issue when saving videos

Hey, thanks for the great library. We are using it in something really cool, and i can't wait to show you!

So, to the problem at hand.
When i'm using the exact same code as the example on iOS, i often encounter a writing error on the AVAssetWriter in SCAudioVideoRecorder.m

*** Terminating app due to uncaught exception 
'NSInternalInconsistencyException', reason: 
'*** -[AVAssetWriter finishWritingWithCompletionHandler:] 
Cannot call method when status is 1'

The error occurs on line 266:

- (void) finishWriter:(NSURL*)fileUrl {
#if TARGET_IPHONE_SIMULATOR || TARGET_OS_IPHONE
    [self.assetWriter finishWritingWithCompletionHandler:^ { // <-- Here
        dispatch_async(self.dispatch_queue, ^{
            [self stopInternal];
        });
    }];

Hope that you can help with this!

Observer-issue with SCPlayer

 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'CoreStreamBase<>(0x15e29718 e:ORWEDM p:orwedm s:O): An -observeValueForKeyPath:ofObject:change:context: message was received but not handled.

        );
    }

Hey, we got a crash on this. Is this something you are aware of? We could certainly take a look at it our self, if you don't have any quick ideas about what this is. It seems to called after the item has removed the observer, but I'm not that familiar with KVO.

Feature request : Take snapshot of the current previewLayer

Would be great if the lib would enable to take a UIImage snapshot of the current previewLayer

as renderInContext doesn't work and you have to use methods that might break with the lib
http://stackoverflow.com/questions/3397899/avcapturevideopreviewlayer-taking-a-snapshot

Recording in landscape

It should support the recording in either landscape or portrait, either by setting in code, or automatically set with the accelerometer info.

If that's difficult to do, then I would appreciate some sample code on how to rotate the video.

Sometime camera can't open

Hey,

Thank for your source code!

I have the issue: sometime camera can't open.

I'm looking forward your reply!

Thanks and best regard!

Issue on startRunningSession when coming from home

Hey,

Thanks for this awesome library.

I have an issue for recording when coming from background. The session is not get recorded. Issue exists in sample application also. Need help on this.

Retake button in example app doesn't reset captured video/audio

I'm trying to follow the example app and it looks like the retake button isn't implemented. Looking at the code I see that it only resets the timer label and ensures that a session exists. Can you please provide some sample code to demonstrate the best way to implement a retake on the current session?

To reproduce:
Tap to record some video (segment A)
Tap retake button
Tap to record more video (segment B)
Tap stop

Expected:
The final output consists of only video segment B

Observed:
The final output is both segment A and segment B

Audio not initialized, video does not record

We are using SCRecorder and we can reproduce an issue on some devices. We see that when running a session, this line:

https://github.com/rFlex/SCRecorder/blob/master/Library/Sources/SCRecorder.m#L329

Will be in a state where _hasAudio = YES but recordSession.audioInitialized = NO

In this state video will not record. Perhaps this is our implementation but in review it seems quite standard. We use lazy instantiation in our implementation which looks like:

- (SCRecordSession *)session
{
    if(!_session) {
        _session = [SCRecordSession recordSession];
        _session.videoSize = CGSizeMake(320, 320);
        _session.suggestedMaxRecordDuration = CMTimeMakeWithSeconds(kMaxRecordingSeconds, 1);
    }
    return _session;
}


- (SCRecorder *)camera
{
    if(!_camera) {
        _camera = [SCRecorder recorder];
        _camera.recordSession = self.session;
        _camera.sessionPreset = AVCaptureSessionPresetInputPriority;
        _camera.videoOrientation = AVCaptureVideoOrientationPortrait;
        _camera.videoEnabled = YES;
        _camera.audioEnabled = YES;
        _camera.device = AVCaptureDevicePositionFront;
        _camera.flashMode = SCFlashModeOff;
        _camera.previewView = self.previewView;
        _camera.delegate = self;
    }
    return _camera;
}

Any ideas why we get this intermittent issue with recording?

Hey, flex. Have you try to save the video with any other size or other qualities?

I noticed that the encode codes about quality setting have commented a few and not working.

Where is the SCFilter.h?

Hi, thank you for your project. It helps me a lot. I want to add a filter on the video. But I can't find the SCFilter.h. Where is it ?

SCAssetExportSession _reader startReading Crash

Hi rFlex,
You were able to fix my last problem really quickly and I'm hoping you can do it again. So I am recording a video using your library and when it is done I set the asset to your SCPlayer and then allow the user to filter on top of it. However when I call upon SCAssetExportSession to get the newly filtered video I have run into a crash. If I have audio enabled on the video that is being recorded when it goes to be exported it causes an exception breakpoint in the method exportAsynchronouslyWithCompletionHandler:(void (^)())completionHandler at the line if(! [_reader startReading]) with a bad access and I can jump over the exception break point and it will export but if I run it on production it crashes the app. However, if I either run it with _recorder.audioEnabled = NO or just change
_audioOutput = [self addReader:[audioTracks objectAtIndex:0] withSettings:@{ AVFormatIDKey : [NSNumber numberWithUnsignedInt:kAudioFormatType] }]; to _audioOutput = nil in the SCAssetExportSession it works because the audio is not being processed. Do you have any ideas what may be causing this issue.

Thanks

Bug

Hi! rFlex
Why when I set the maximum recording time, has been holding down the record button, but there is an error? If it is intermittent recording wouldn't appear error. (meaning: holding down up down up)

Getting slow framerate with iPhone 4

Im getting a slow framerate while visualizing the video feed, As well as the generated video while been played. This is not happening in iPhone 5 or Iphone 4S.

Which property should I configure to help iphone 4 processor get to and optimal video??

Thank you very much.

Whether it can be ported to android platform?

Focus mode read only

The auto focus goes crazy sometimes, especially in the beginning of the video and there's no apparent way of changing it. The "focusMode" property on an SCRecorder instance is read only, so I can't change it there either.

Question

Hello, @rFlex
thanks for the great source, it works like a charm.
however i have a litte problem : How to do a video recording as instagrm section removed ?，I saw your NSArray+SCAdditions is used for this function？

Add loading view feature

Hi. First of all, Thanks for @rFlex for providing us this awesome framework! I love to use this framework and modify it.
I was working on my project and came up with an idea to improve this project. I think we need more sophisticated loading view. I use horizontal collection view for playing multiple videos with SCPlayer and SCVideoPlayerView in my project. The videos are loaded from server and cached before they played. But while the videos are downloaded, the loading view is not so responsive and beautiful.

I thought it would be helpful to community wide if we can add video downloading feedback feature with first frame of video screen as a loading view and the alpha value of the view like Mindie.

Thanks!

Brand new implementation

Hey guys,

I just pushed the brand new implementation. I renamed the project to SCRecorder. A lot of things changed (actually, pretty much everything changed). You will have to learn the library from scratch again, sorry about that :(.

Now let's talk about the good things!

I spent a lot of times trying to make this new implementation totally stable, you shouldn't experience crash. We all know though it can still happen on any piece of software, so if you experience something that I didn't expect, feel free to let everyone know so we can try to find a solution!
As Instagram and Vine does, you can now delete while recording parts from your videos. A part is called "recordSegment", see the documentation for more explanation.
You can start a record session in 2014, and finish it 4 years later.
You can play a record session, edit it and resume it.
The new implementation might be a little more complicated to use, even though I tried to make it the most straightforward as possible despite the fact that it adds a lot of news possibilities for you guys.

If you have any questions, feel free to ask in this topic!

Cheers,

Simon

Source files missing in cocoapods

Hello :)

First of all, thanks for nice library. I'm using this sources in my project,
and you save my time!

I'm using sources by direct importing your sources which I downloaded
zip file from github in my project.

I want use your sources as cocoapods, but when I update my Podfile and saw
the source files in the pod project, several sources are missing.

There are no sources related filters. I think you've missed your pods.
Please check this issue. Thanks.

Video, audio not getting recorded during interruption like Skype call.

Receive call or call from the device through Skype. Now open the application (SCRecorderExamples) and begin recording. Seems like, first segment recorded successfully but it isn't. Can not record again. Navigate to preview, no video will be shown. Delegate methods, recorder:didAppendVideoSampleBuffer: & recorder:didAppendAudioSampleBuffer: are not getting called.

If Skype calls arrives while recording, we can continue recording but there will not be any sound for the video while playing on preview view.

While putting breakpoints here and there I got these two errors.

ERROR: [0x103534000] AVAudioSessionPortImpl.mm:50: ValidateRequiredFields: Unknown selected data source for Port iPhone Microphone (type: MicrophoneBuiltIn)

End record segment -1, error : Error Domain=AVFoundationErrorDomain Code=-11821 "Cannot Decode" UserInfo=0x178271240 {NSUnderlyingError=0x17824b1f0 "The operation couldn’t be completed. (OSStatus error 560226676.)", NSLocalizedFailureReason=The media data could not be decoded. It may be damaged., NSLocalizedDescription=Cannot Decode}

Problems is in iOS7. When you set audioEnabled property of SCRecorder to NO, works perfectly but without sound.

Please look into this issue.

fileExistsAtPath returning no

Hello,

THANKS for all the work :)

   [[NSFileManager defaultManager] fileExistsAtPath:[_recordSession.outputUrl path]]) is returning NO in "finishSession".

Is that on purpose?

Thanks in advance.

Video With enableSound go problem.

Save Recorded Session Error

I've been trying many different ways to get a video to be after the recording session. First, I'm having problems actually stopping the session. Calling endRunningSession does nothing and even other methods still doesn't stop the session. Basically didCompleteRecordSession never gets called.

Add rotation support

Accessing the AVCaptureSession on separate queue

There doesn't seem to be any pattern with how you access the capture session on your _dispatchQueue.

For example, on openSession:, you do this on the current queue:

AVCaptureSession *session = [[AVCaptureSession alloc] init];
 _beginSessionConfigurationCount = 0;
 _captureSession = session;

But then later on you do:

if (!_captureSession.isRunning) {
     dispatch_async(_dispatchQueue, ^{
          [_captureSession startRunning];

Why are you accessing the capture session from different queues? At first I ignored it thinking it was harmless, but I noticed that many times when I tried using the recorder, the entire iOS media server would crash, and this notification would be posted:

AVAudioSessionMediaServicesWereResetNotification

I forked your repo, and moved all access of the capture session to its respective queue, and I no longer see this issue.

On a separate note, you don't seem to be handling any of the error notifications, such as:

AVCaptureSessionRuntimeErrorNotification
AVCaptureSessionWasInterruptedNotification
AVAudioSessionMediaServicesWereResetNotification
AVAudioSessionMediaServicesWereLostNotification

How to change video dimensions and quality

Great Library,
But is there a way to change the 1080x1920 to something smaller ?
like Vine.. which are squared videos no very big, and great for Uploading to a server.
because of the file size ...

Also.. I have a question regarding the TEMP directory. When is the /tmp directory flushed ? I see all videos stored there since the very beginning.

Can't save video to cameraroll

Hi rFlex,

I use SCRecorder, it works well, but I want to save video file after recording to cameraroll, but I can't.

Please help me!

Thanks!

Q: mp4?

I'm sorry, i want ask, is it possible to save the video file in the container 'mp4'

Can't resume capture

Hi fFlex,

I want to resume capture video, I followed your guide:
// Get a dictionary representation of the record session
// And save it somewhere, so you can use it later!
NSDictionary *dictionaryRepresentation = [recordSession dictionaryRepresentation];
[[NSUserDefaults standardUserDefaults] setObject:dictionaryRepresentation forKey:@"RecordSession"];

// Restore a record session from a saved dictionary representation
NSDictionary *dictionaryRepresentation = [[NSUserDefaults standardUserDefaults] objectForKey:@"RecordSession"];
SCRecordSession *recordSession = [SCRecordSession recordSession:dictionaryRepresentation];

but I can't resume capture video.

do you have any different way?

Thanks!

Save video file

Hi,

I tried your exampe for iOS for test purpouses. It seems to work great but it doesn't save the video to the CameraRoll. It asks for permission the first time, it says that video has been successfully saved but there is nothing there.

[Suggestion] Tap to pause current video frame

Hi There,
The library is amazing however it would be even better if you could implement a tap to view current frame. eg while viewing a vine, if you tap on the vine it pauses itself and resumes when you tap it again.

Preview View not Auto-Rotating

Attached is an image of what's happening.

When I rotate the phone, the rest of the views in the XIB rotate and scale properly, but the preview layer basically stays the same. When recording, the video does come out properly, it's just the preview layer.

Record Session Terminated Automatically?

For some reason the record session restarts when taking a few clips:

"2014-07-25 19:48:42.315[1210:327713] Initialized audio in record session
2014-07-25 19:48:42.322[1210:327713] Initialized video in record session
2014-07-25 19:48:42.322[1210:327713] Began record segment: (null)
2014-07-25 19:48:42.324[1210:327713] End record segment -1: (null)
2014-07-25 19:48:54.290[1210:327713] Began record segment: (null)
2014-07-25 19:49:07.480[1210:327713] End record segment -1: (null)"

Any ideas?

[Suggestion] Square Video like Vine/Instagram

If there isn't already a method to do so. This would be nice. Thanks!

Error: Remove any record segment that you don't want

Hi,

I follow your guide to remove the record segment like this:

[recordSession removeSegmentAtIndex:1 deleteFile:YES];
or
[recordSession removeSegmentAtIndex:1 deleteFile:NO];

I have 2 cases with the error:

record 2 segments (open camera, tap and hold 2 times), then remove both 2 segments, continue to record, then convert video --> can't convert
record 3 segments (open camera, tap and hold 3 times), then remove the third segment, then record addition 1 segment, then convert video --> video result have 2 segment (the first and the second segment, not have the four segment)

I'm looking forward your help!

Thanks and best regard!

When trying to set the video orientation like so:

        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            [self.camera startRunningSession];
        });

    }];
}

Problem with merge

When merging record segments or even just getting the assetRepresentation, some segments seem to be missing. The recordSegments.count seem correct, and end record segment log seems correct, however the video/asset output seems to be incorrect. Say the count is 4 (segments) the end video will show only 3 of the segments leaving out an appended video segment. I notice this happening when I delete and append segments. Any ideas? or sample project showing correct way to implement delete and add as I may be doing something wrong.

I'm unable to pinpoint the exact location of the problem or to recreate the issue all the time. It seems to be almost random.

Problem switching camera device while paused on iPhone 4

I have noticed that on my iPhone 4S there is a problem with switching the camera in between calls to pause and record. It does not matter which camera device you start with - when switching to the other camera and resuming record no video will be captured to the session. I have tried this with my own project as well as the sample project you provided and see the same issue.

This behavior currently works as expected in testing on multiple iPhone 5 devices

One thing to note is that there is no issue when switching the camera during recording. The problem only appears when you have paused the recorder and then do the switch.

Steps to reproduce on iPhone 4S running 7.1.1:

Start running session normally with either front or back camera
Record video
Pause
Switch the camera device
Resume recording
Repeat steps 3-5 if desired
End session and play output video

Observed:
No video is recorded by the camera that was switched to during the pause

Recording square video

I'm having trouble configuring the recorder to capture and export video cropped to a square aspect ratio. Without expertise in AVFoundation I am having a hard time understanding whether this is currently possible to do. Is this currently a supported feature for iOS?

I can see that Issue #1 relates to this question but it was closed 7 months ago and the codebase has changed since that resolution. Specifically, it seems that the functionality associated with useInputFormatTypeAsOutputType has been rewritten.

I have tried to configure the recorder using the following methods without success:

camera.videoEncoder.outputVideoSize
camera.sessionPreset
[camera setActiveFormatThatSupportsFrameRate:width:andHeight:error:]

Any information on this matter would be greatly appreciated.

Should we add a sessionPreset property to manage video/photo quality?

NSString *const AVCaptureSessionPresetPhoto;
NSString *const AVCaptureSessionPresetHigh;
NSString *const AVCaptureSessionPresetMedium;
NSString *const AVCaptureSessionPresetLow;
NSString *const AVCaptureSessionPreset352x288;
NSString *const AVCaptureSessionPreset640x480;
NSString *const AVCaptureSessionPreset1280x720;
NSString *const AVCaptureSessionPreset1920x1080;
NSString *const AVCaptureSessionPresetiFrame960x540;
NSString *const AVCaptureSessionPresetiFrame1280x720;

removeSegmentAtIndex: deleteFile: is error

I use cocoapod to added : pod 'SCRecorder', '~> 2.0.14'
and i use the methed：
removeSegmentAtIndex: deleteFile:
to remove a segment,

after i removed a segment, and i updateTimeRecordedLabel, and refresh the correct time use under code:
if (_recorder.recordSession != nil) {
currentTime = _recorder.recordSession.currentRecordDuration;
}

self.timeRecordedLabel.text = [NSString stringWithFormat:@"%.2f S", CMTimeGetSeconds(currentTime)];

but the time error, the time was not changed, when i removeSegmentAtIndex twice! the time was changed!!
