前幾幀是黑色的；
背景色是藍色的；
靜音錄製崩潰；
push 的時間延遲；

前幾幀是黑色的，https://github.com/BradLarson/GPUImage/issues/1255static BOOL allowWriteAudio = NO;- (void)startRecording;{  ...  allowWriteAudio = NO;}- (void)processAudioBuffer:(CMSampleBufferRef)audioBuffer;{  if (!allowWriteAudio) {    return;  }  ...}- (void)newFrameReadyAtTime:(CMTime)frameTime atIndex:(NSInteger)textureIndex;{  ...  if (![assetWriterPixelBufferInput appendPixelBuffer:pixel_buffer withPresentationTime:frameTime])    NSLog(@"Problem appending pixel buffer at time: %@", CFBridgingRelease(CMTimeCopyDescription(kCFAllocatorDefault, frameTime)));  allowWriteAudio = YES;   //< add this  ...}

push 的時間延遲bug            //只有一段視頻            [KJUtility hideProgressDialog];            NSDictionary *dict = self.kj_videoArray.firstObject;            self.kj_outPath = dict[@"path"];            [self saveVideoToLibrary];            WS(weakSelf)            if (self.kjFileDelegate && [self.kjFileDelegate respondsToSelector:@selector(kj_videoFileCompleteLocalPath:)]) {                NSLog(@"一段視頻：.........%@",self.kj_outPath);                [self.kjFileDelegate kj_videoFileCompleteLocalPath:self.kj_outPath];            } else {                [self saveVideoToLibrary];            }

藍邊的bug//        kj_movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:videoURL size:CGSizeMake(SCREEN_WIDTH, SCREEN_HEIGHT)];        kj_movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:videoURL size:CGSizeMake(floor(1080), floor(1920))];

靜音的bugAVURLAsset *kj_videoAsset = [[AVURLAsset alloc] initWithURL:tmpUrl options:kj_options];        if ([[kj_videoAsset tracksWithMediaType:AVMediaTypeAudio] count] > 0){            kj_movieComposition.audioEncodingTarget = kj_movieWriter;        } else {//no audio            kj_movieComposition.audioEncodingTarget = nil;        }//        kj_movieComposition.audioEncodingTarget = kj_movieWriter;

 if ([[anAsset tracksWithMediaType:AVMediaTypeAudio] count] > 0){            _movieFile.audioEncodingTarget = _movieWriter;        } else {//no audio            _movieFile.audioEncodingTarget = nil;        }
