Although there are related extensions, they cannot be killed. Many of them are targeted at YouTube or some foreign online radio stations.
You can enter /extensions?hl=zh-CN Search for keyword FLV link or Streaming Media I personally test it none of you support Youku. Other online listening sites have not been tested. Of course, you can manually ask other sites to find addresses for you. , In addition, some third-party software can be used to intercept it with wincap software
Tips for supporting most web pages
1. First find the URL of the play media and open it, for example, find a song in Google Music and play it in its web player
2. Right-click the blank position of the web page. Review elements -- Resources. Then generally select the following documents or other, and then pull the scroll to find the file with a certain extension you expect. For example, here is Google Music. All of them are mp3, so I found a shape like M0104220007.mp3 (Xu Guanjie Ye Ye Niannujiao http://audio2./201008251822/8FBFD1FCB2A88B303E3520C726513710/streaming1/Special_104220/M0104220007.mp3)
3. Suppose you don’t refresh the web page and play several songs in a row. So many MP3 files will be found here, so you have to refresh before you can intercept the address next time
1. Open the web page - right-click the blank position of the web page - review elements - Resources - Other
2. Find 03000201004B95A3... and find the Request URL on the right: /player/getFlvPath/sid/128273323710911092595_00/st/flv/fileid/03000201004B95A3BDB0AB0059E31C987E9294-5895-E061-B1B6-999CE6BD28EC?K=39770cedec12c823161b2f45&myp=0&ts=198
Open it in the address bar and you can download it. Since the browser will reference the cache, it will not download it repeatedly. And directly extract the cache.
So in fact, you can download it without looking for the address. When the streaming media is buffered, you can open its cache directory. Find the corresponding file and change the file name, ok.
Replenish
Extract media files using Chrome Cache Directory
Please check your Chrome version number (WinXP environment)
Version number, first open the browser. Press Ctrl+Shift+Delete to clear all data (choose as appropriate, but it is recommended to check "Clear cache" so that you can easily find it when looking for files, because Chrome's cache files are all f_0000**);
Then open and buffer the required web page file. Open C:\Documents and Settings\{current username(Administrator)}\Local Settings\Application Data\Chromium\User Data\Default\Cache again, sort by size. Find the expected corresponding file, copy it to other folders, and change the extension (the video files of general online video sites may be of normal quality FLV, F4V format, "HD" qualityMP4 format）
Note: Google video cache folder for win7 system: C:\Users\Administrator\AppData\Local\Google\Chrome\User Data\Default\Pepper Data\Shockwave Flash
Except for other version numbers of Chromium, the operation is similar to the above, except for the cache directory path. C:\Documents and Settings\Administrator\Local Settings\Application Data\Google\Chrome\User Data\Default\Cache3. Use ChromeCacheView, open the software and set the corresponding path according to the above folder. If it is Chrome, it is not necessary.
Find a file with a larger file or a specific icon (whether the media format is associated with the playback software) and right-click "Save Selection" to save file information. Open the saved TXT and see the network path of the file. You can download it.
Of course, there is 1/2 step. This download is meaningless, so it is not recommended to use it.
