Setting SCImageView on Player stops playback.

[MMasterson]

I've been trying to implement filters, but I am having several issues. The code below should work, but there is 0 playback.

    [_playerView setFrame:[[self containerView ] bounds]];
    [[ _playerView player] setItemByAsset:[[self recordSession] assetRepresentingSegments]];
    [[ _playerView playerLayer] setFrame:[[self containerView ] bounds]];
    [[ _playerView playerLayer] setVideoGravity:AVLayerVideoGravityResizeAspectFill];

    [[ _playerView player] setDelegate:self];
    [[ _playerView player] setLoopEnabled:YES];
    [[ _playerView player] beginSendingPlayMessages];

    [[ _playerView player] play];

    SCFilterImageView *filterView = [[SCFilterImageView alloc] initWithFrame:[[self containerView ] bounds]];
    filterView.filter = [SCFilter filterWithCIFilterName:@"CIPhotoEffectInstant"];
 [[_playerView player] setSCImageView:filterView];

when I remove
[[_playerView player] setSCImageView:filterView];

The video plays...

Anyone have any luck on gettings Filters working with SCRecorder?

[MMasterson]

I've added
[_playerView insertSubview:filterView belowSubview:_playerControlsView];

and moved

[[ _playerView player] setItemByAsset:[[self recordSession] assetRepresentingSegments]];

and it is now working intermittently. Takes a few times to get the video to actually play through the filter.

The end goal is to use the Swipe View but I've had 0 luck with that.

@MMasterson Maybe I met the same problem, could you please describe what is _playerView and _playerControlsView in your code?

[MMasterson]

sure @shiweige

_playerView is an outlet of SCVideoPlayerView on the story board and _playerControlsView is an outlet of a UIView that holds the play button, next and cancel button for the camera.

@MMasterson you don't need the SCplayerView since your renderer will be the SCFilterImageView or your future SwipeableFilterVIew.
First, initialize your scPlayer.

self.scPlayer.shouldSuppressPlayerRendering = NO; [self setupFilterSwitcher]; self.scPlayer.SCImageView = self.swipeableFilterView;

Then
- (void)setupFilterSwitcher { self.swipeableFilterView.filters = <your filters>; self.swipeableFilterView.delegate = self; //If you need it self.swipeableFilterView.contentMode = UIViewContentModeScaleAspectFit; //or whatever }

my self.swipeableFilterView is an outlet from my storyboard.
That should do it.

@sherm4n90 I've made the appropriate changes

Changed my SCplayerView to a SCSwipeableFilterView and reconnected it as an outlet named swipeableFilterView

in my viewDidLoad
I've added

  if(_player == nil){
        _player = [[SCPlayer alloc] init];
    }

I've added your method

- (void)setupFilterSwitcher {
    self.swipeableFilterView.filters = @[[SCFilter filterWithCIFilterName:@"CIPhotoEffectNoir"],
                                         [SCFilter filterWithCIFilterName:@"CIPhotoEffectChrome"],
                                         [SCFilter filterWithCIFilterName:@"CIPhotoEffectInstant"],
                                         [SCFilter filterWithCIFilterName:@"CIPhotoEffectTonal"],
                                         [SCFilter filterWithCIFilterName:@"CIPhotoEffectFade"]];
    self.swipeableFilterView.delegate = self;
    //If you need it
    self.swipeableFilterView.contentMode = UIViewContentModeScaleAspectFit; //or whatever
}

in my viewDidAppear
I've added

    _player.shouldSuppressPlayerRendering = NO;
    [self setupFilterSwitcher];
    _player.SCImageView = self.swipeableFilterView;

and it does play the video although, the swipe does not work - as in the filters do not change

@MMasterson did you try the - (void)swipeableFilterView:(SCSwipeableFilterView *__nonnull)swipeableFilterView didScrollToFilter:(SCFilter *__nullable)filter protocol method? This will tell you if the scrolling through filters is working.

Edited: also you may need:
- (void)viewDidLayoutSubviews { [super viewDidLayoutSubviews]; [self.swipeableFilterView setNeedsDisplay]; }

[MMasterson]

@sherm4n90 - It is not being called - but can't seem to figure out why.

Is there a User Interaction field I have to enable programmatically?

[MMasterson]

@sherm4n90 even with your edit, no luck on getting the gesture to fire.

[glm4]

@MMasterson mm, nothing to add, maybe you have some view covering the swipeableView.

[MMasterson]

@sherm4n90 yup.. just double checked, had a view over the swipeView...

Thank's so much for your help with the set up!

@MMasterson great! glad to help
