letcancelable=compressh264VideoInBackground(
videoToCompress: videoToCompress,
destinationPath: destinationPath,
size:nil, // nil preserves original,
//size: (width: 1280, height: 720) compressionConfig:.defaultConfig,
progressQueue:.main,
progressHandler:{ progress in // Handle Progress
},
completion:{[weak self] result inswitch result {case.success(let url):
