PHP exec calls FFmpeg automatic transcoding video does not execute To a customer to do phpcms field development, in fact, the transfer of video transcoding function, the local test passed, UAT environment also passed. After the customer uploads to the production environment, Transcoding does not execute, UAT environment and production environment, are WIN2003+IIS

URL to pass the Chinese parameters when the several processing methods, summarized as follows:1. Transcode The string: newstring ("xxxxx". GetBytes ("Iso-8859-1"), "Utf-8")This transcoding method has great drawbacks because it uses the specified character set to encode this string into a byte sequence, stores the result in a new byte array, and then decodes the resulting byte array by using the specified character encoding to construct a new string st

When using PHP json_encode to handle Chinese, Chinese will be encoded, become unreadable, similar to the "\u***" format, if you want Chinese characters do not transcode, here are three ways 1. Upgrade PHP, in PHP5.4, the problem is finally resolved, JSON added an option: Json_unescaped_unicode, so the name Incredibles, that is, JSON do not encode UNICODE. 2. UrlEncode the Chinese characters first and then use the Json_encode,json_encode again after using the UrlDecode to decode, so that the en

In development, we often need to change the N-file encoding, ICONV can only make changes to a single file, how to do? Let's write a shell script to solve this problem. Example one: Using shell script to implement bulk transcoding operation. #!/bin/sh # convertcodefilepath=$1 fromcode=$2 tocode=$3 for i ' {1..1} do [-f $convertCodeFilePath] if [ $? -eq 0] Then iconv-f $fromCode-T $toCode-C-O $convertCodeFilePath $convertCodeFilePath if [$-ne

I added a coded sentence to the JSP file: Then, in the program, make a transcoding of the Chinese character: In the database: Name=request.getparameter ("name"). Trim (); Name=new String (name2.getbytes ("GB2312"), "iso-8859-1"); To remove from the database: Listname=new String (rs.getstring ("name"). GetBytes ("Iso-8859-1"), "GB2312"); and database, Tomcat is using the default encoding.

Method One: If we install "Storm Code 1.0", we just drag the file to the transfer code directly into the storm.Method Two:1. This is also the opening of the storm after we click "Add Files" and will pop up to select the computer to transfer the code of the video file 3. Select the file that requires transcoding (you can use CTRL or SHIFT to select multiple), and then click on "Open" which is very simple to choose a number of files. 3. OK to add th

compatible gb2312 , but not all can turn back to each other, it is best to use iso-8850-1 as the intermediate transcoding character set, because all the character sets are iso-8859-1 compatible, whether GBK or gb2312,utf-8, can be perfectly converted back. Say so much, perhaps everybody still a little confused, this application is in where. I give an example, you know, often some people do web crawler, download the Web page, but, a variety of Web pa

Java enumeration Transcoding If unified transcoding (tomcat, spring, and so on) is not completed in web projects, garbled characters will inevitably occur. Various online solutions may not be the right remedy" So I wrote a small tool to perform transcoding in enumeration mode. After reading the results, I can use the correct one. It's simple and rough!
