<Script>   //Upload Video    $('Input[name=fileupload]'). Change (function () {        //Console.log ("in It");layer.msg ('Upload video ...

The video is uploaded using XMLHttpRequest.

Use XMLHttpRequest. upload.onprogress to display upload progress

Receive code in the background

[HttpPost] PublicActionResult Indexs (formcollection collection) {HttpPostedFileBase file= httpcontext.request.files[0]; if(File! =NULL)            {                if(file. Filename.length >2&& Filename.tolower (). IndexOf (". mp4") <0)                {                    returnWriteerror ("please upload. MP4 Formatted Videos"); }            }            stringFileName = GetFileName (file. FileName);//GetFileName ();            stringSavename = DateTime.Now.ToString ("yyyymmddhhmmssffff") +FileName; stringPlayfile = Server.MapPath (Publicmethod.upfile +savename); stringUpfilename = Publicmethod.upfile +Savename; //upload video to localfile.            SaveAs (Playfile); //upload video to seven knQiniufun.        Putfile (Qiniufun.qnspace, Qiniufun.fullname (Upfilename), Server.MapPath (Upfilename)); }         Public stringGetFileName (stringfileName) {            inti = Filename.lastindexof ("\\") +1; stringName =filename.substring (i); returnName; }

The following issues occurred during the upload to seven kn

1. Use normal upload mode to upload only the file size within 100M of the video

Speaking of which, we're going to throw a notch. Seven KN SDK, the example code method names and methods on the DLL and official documents downloaded from NuGet are not available.

2. The uploaded video cannot be played on both the PC side and the phone

For the above question seven cows have a little trick to see the encoding of the video

http://7xo9nf.com2.z0.glb.qiniucdn.com/test.mp4?avinfo//Video address +? Avinfo

Solution: Use the Format factory to change the video encoding to AVC (H262) or ACV (H264) encoding

All right, after solving the above problems, we find that publishing the code to the IIS Environment Code has the following problems

1.mp4 formatted file IIS is not recognized

Add the MIME type of the video. MP4 Video/mp4

2. Uploading folder access permissions issues

3.iis Upload File size limit

Select site Home-"Request Filter-" Edit feature Settings-"Set allow maximum content length

4. Time limit for requests

Webconfig Settings and XMLHttpRequest settings
