kCMSampleBufferAttachmentKey_TrimDurationAtStart error

Question

Getting an error when trying to convert a video recorded from camera or picked from gallery: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[AVAssetWriterInput appendSampleBuffer:] Cannot append sample buffer: First input buffer must have an appropriate kCMSampleBufferAttachmentKey_TrimDurationAtStart since the codec has encoder delay'`

This is discussed here: CMSampleBufferRef kCMSampleBufferAttachmentKey_TrimDurationAtStart crash

But no resolution was reached.

Here is my code:

[self.audioInput requestMediaDataWhenReadyOnQueue:self.audioQueue usingBlock:^{
        CMSampleBufferRef buffer;
        LIMTAssetFileWriter * __strong strongSelf = weakSelf;
        while (strongSelf.audioInput.isReadyForMoreMediaData) {
            LIMTPayload *payload = [strongSelf.cache dequeuePayloadForType:LIMTPayloadTypeAudio];
            buffer = payload.getCMSampleBuffer;
            if (buffer) {
                if (!strongSelf.sessionStarted) {
                    [strongSelf.assetWriter startSessionAtSourceTime:CMSampleBufferGetPresentationTimeStamp(buffer)];
                    strongSelf.sessionStarted = YES;
                }
                [strongSelf.audioInput appendSampleBuffer:buffer];
                [LIMTLogger.sharedLogger logInfo:@"Audio buffer appended"];
                CFRelease(buffer);
                buffer = NULL;
            } else if ([strongSelf.cache statusForType:kCMMediaType_Audio] == LIMTCacheStatusCompleted) {
                [strongSelf.audioInput markAsFinished];
                [LIMTLogger.sharedLogger logInfo:@"Audio complete"];
                dispatch_group_leave(strongSelf.dispatchGroup);
                break;
            } else {
                break;
            }
        }
    }];

Error is happening here: [strongSelf.audioInput appendSampleBuffer:buffer];
