push 的时间延迟bug
//只有一段视频

蓝边的bug
// kj_movieWriter = [[GPUImageMovieWriter alloc] initWithMovieURL:videoURL size:CGSizeMake(SCREEN_WIDTH, SCREEN_HEIGHT)];

静音的bug
AVURLAsset *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;
