There is not a small amount of information online about MP4, but there is almost no way to tell a container from a pseudo-code level to another container, which is why you write a series of articles.
This article is mainly about parsing FLV format video, detailed FLV knowledge please see this blog
http://blog.csdn.net/leixiaohua1020/article/details/17934487
FLV format is very simple
FLV Head >4 Bytes Last tags size >metadata tags>4 bytes 4 bytes Last tags size > video tags>4 bytes last tags size > audio tags>4 bytes last tags size > .... >4 bytes Last tags size
It's basically a format.
So decoding FLV is also very simple
We're dividing it into 3 parts.
| METADATA Tag | Video Tag | Audio Tag |
|---|---|---|
| There is only one | There are multiple | There are multiple |
First, the FLV is loaded into a binary array in any way
<body> <div> Drag flv files here </div> <script type= "Text/javascript" src
= "Bound.js" ></script> <script> var dropbox=document.queryselector (' body div ');
Dropbox.addeventlistener ("DragOver", function (e) {e.stoppropagation ();
E.preventdefault ();
}, False);
Dropbox.addeventlistener ("Drop", function (e) {e.stoppropagation ();
E.preventdefault ();
var reader = new FileReader ();
Reader.addeventlistener ("Load", processflv, false);
Reader.readasarraybuffer (E.datatransfer.files[0]);
}, False);
function processflv (e) {var buffer=e.target.result;
var uint8=new uint8array (buffer); Console.log (uint8); Drag-and-drop FLV video into a 2 binary array flvparse.setflv (UINT8);//Still into converter} </script> </body>
This code in the project inside the index.html inside, this chapter is finished, the next chapter explains the FLV parsing
