Terminated due to memory issue

[Neil20170220]

I try to export video with GPUImageColorInvertFilter for infinite times, momery occupy by Other processes increase continuously, and the App is killed finally.

I test use iPhone 8, iOS 11.2.1, Xcode 9.2.

Here is my code:

- (void)export {
    self.index++;

    NSLog(@"------ loop %lu begin ------", self.index);

    NSURL *sampleURL = [[NSBundle mainBundle] URLForResource:@"Video-20171220-121803" withExtension:@"MP4"];

    self.movieFile = [[GPUImageMovie alloc] initWithURL:sampleURL];
    self.filter = [[GPUImageColorInvertFilter alloc] init];

    [self.movieFile addTarget:self.filter];

    NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSDate *now = [[NSDate alloc] init];
    NSString *pathToMovie = [NSString stringWithFormat:@"%@/%@.mp4", documentsPath, now];

    NSURL *movieURL = [NSURL fileURLWithPath:pathToMovie];

    self.movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:movieURL size:CGSizeMake(3280, 2460)];
    [self.filter addTarget:self.movieWriter];

    self.movieWriter.shouldPassthroughAudio = YES;
    self.movieFile.audioEncodingTarget = self.movieWriter;
    [self.movieFile enableSynchronizedEncodingUsingMovieWriter:self.movieWriter];

    [self.movieWriter startRecording];
    [self.movieFile startProcessing];

    __weak typeof(self) weakSelf = self;
    [self.movieWriter setCompletionBlock:^{
        [weakSelf.movieWriter finishRecordingWithCompletionHandler:^{
            [weakSelf.movieFile endProcessing];
            [weakSelf.movieWriter endProcessing];

            [weakSelf.movieFile removeAllTargets];
            [weakSelf.filter removeAllTargets];

//            [weakSelf.movieWriter.movieWriterContext.framebufferCache purgeAllUnassignedFramebuffers];
//            [[GPUImageContext sharedFramebufferCache] purgeAllUnassignedFramebuffers];

            weakSelf.movieFile = nil;
            weakSelf.movieWriter = nil;
            weakSelf.filter = nil;

            NSLog(@"------ loop %lu end ------", weakSelf.index);

            dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
                [weakSelf export];
            });
        }];
    }];
}

I also happend to this problem,i using GPUImageScreenBlendFilter ,export the video successfully,but then the app killed,xcode get the same error with you .

[Neil20170220]

@Nycojie after search and search, i find https://github.com/BradLarson/GPUImage/pull/2549 fix this issue!

[Nycojie]

@Neil20170223 ,i try it ,but it does't work/(ㄒoㄒ)/~~ i add some code to my program，let the two movieFile remove all the targets,then the app not crash.Before i use two movieFile and not add 'remove all the targets', it work well too.

[Neil20170220]

@Nycojie 不清楚你的流程是什么样的, 你也是做压力测试?

I am trying to add green screen effect on the video for that i am using gpuimagechromakey Filter. It is crashing after 2-3 seconds and give message from debugger Message from debugger: Terminated due to memory issue.

@sagarkoyani
Merge the two videos together? Or green screen video as a video filter?

[sagarkoyani]

@Nycojie green screen video as a video filter
