mp4转ts：
pod 'FFmpegWrapper', '~> 1.0'
FFmpegWrapper *wrapper = [[FFmpegWrapper alloc] init];
[wrapper convertInputPath:inputFilePath outputPath:outputFilePath options:nil progressBlock:^(NSUInteger bytesRead, uint64_t totalBytesRead, uint64_t totalBytesExpectedToRead) {
} completionBlock:^(BOOL success, NSError *error) {
success?NSLog(@"Success...."):NSLog(@"Error : %@",error.localizedDescription);
}];
inputFilePath:mp4文件地址 outputFilePath：输出的ts文件地址
