字节数组转 mp4box



const bytesStr =

00 00 00 21 61 76 63 43 01 64 00 1F FF E1 00 0A
27 64 00 1F AC 56 80 50 05 B9
01 00 04
28 EE 3C B0

;

const dataArray = hexStringToUnit8Array(bytesStr);

const box = AVCC.parse(dataArray);

console.log(box);





 mp4box 转 Unit8Array



    const avccBox = new AVCC();

    avccBox.configurationVersion = 1;
