we usually generate caches when we surf the internet to listen to music, but it's hard to extract the video and music files from some software .
For the Chrome browser mentioned in this article, as mentioned in the previous blog post, please scroll through:Http://blog.sina.com.cn/s/blog_6fa5aa4a010136l5.html in Chrome, you can use the F12 key to examine the features of the original video or music source address, can be downloaded from the source address
First of all, how to crawl Video: 1. Open the video address, such as: http://www.tudou.com/albumplay/BDG9NP__xZ8.html
2. Press F12
Dot Network
Press F5 to refresh the page, point size
Find the largest file with the file suffix f4v, which is the video file
Right-click on the largest file to copy the file link address
Paste the address into the address bar or paste into the Thunder and other download software can be downloaded
The above method for extracting video method, Youku video file suffix named flv
In fact, for the extraction of video files There is a more convenient way, just login: http://www.flvcd.com/, in the Address bar to enter the video address to extract video files, please refer to the website instructions
For music files, the method is the same, the general file suffix is MP3,
However, this method only try to PPAPI type of Flash plug-in, for the use of other types of flash plugin is not, you can use the Chromecacheview
now, although there are extensions, it's not going to kill a lot. YouTube or some foreign Internet radio stations are targeted.
You can go to https://chrome.google.com/extensions?hl=zh-CN search keyword FLV link or streaming Media I do not support Youku other online listening songs website not tested. Of course, you can manually let other sites to help you find the address, http://www.flvxz.com, you can also use some third-party software with the Wincap software to intercept
But I found a small trick, use may need a little brain juice (to be a little eng Oh, the operation is not simple, so only recommend software evaluator). It is estimated that most web pages can be supported.
1. First find the URL of the broadcast media and sick open, for example, find a song in Google Music and play in its web player
2. Right-click on the page blank position, review the element--resources, then generally select the following documents or other, and then pull the scroll bar to find your estimated extension of the file, such as this is the Google Music species are all mp3, I found a shape like M0104220007.mp3 (Sam Hui every night to read slave jiao http://audio2.top100.cn/201008251822/8FBFD1FCB2A88B303E3520C726513710/ Streaming1/special_104220/m0104220007.mp3)
3. If you do not refresh the page, play several songs in a row, you will find so many MP3 files here, so to refresh before the next intercept address
Here's a test on Youku: (Sam hui pear Vortex Light laughter http://v.youku.com/v_show/id_XMTMzODk2MzI=.html)
1. Open Web page--Right-click Page blank position--review element--resources--other
2. Find 03000201004b95a3 ... and find the request Url:http://f.youku.com/player/getflvpath/sid/128273323710911092595_00/st/flv/fileid/on the right. 03000201004b95a3bdb0ab0059e31c987e9294-5895-e061-b1b6-999ce6bd28ec? k=39770cedec12c823161b2f45&myp=0&ts=198
Opens in the address bar and can be downloaded because the browser references the cache, so it does not repeat the download and extracts the cache directly.
So in fact, you can not find the address to download, such as streaming media buffer is over, open its cache folder, find the corresponding file, modify the filename, OK.
Add:
Extracting media files using the Chrome cache folder
Please check your chrome version first (WinXP environment)
1.Chromium version, first open the browser, press Ctrl+shift+delete to clear all data (optional, but it is recommended to "clear the cache" tick, so that the search for files easy to find, because the chrome cache files are f_0000**) Then open and buffer to complete the required Web page file, then open C:\Documents and settings\{Current user name (Administrator)}\local Settings\Application Data\chromium\ User Data\default\cache, sort by size, find estimate corresponding file, copy to other directory, modify extension (General online video site video file may be in normal quality flv,f4v format, "HD" Quality MP4 format)
2.Chrome In addition to other versions of chromium, similar to the above operations, except that the cache folder path is different C:\Documents and Settings\Administrator\Local Settings\Application Data\google\chrome\user Data\default\cache
3. Using Chromecacheview, open the software according to the above directory to set the corresponding path, chrome is not necessary. Find the file larger, or a specific icon of the file (in the media format is played by the Software Association) right-click "Save Selection" to save the file information, and then open the saved txt, see the file network path, you can download. Of course, with 1/2 steps, this download is meaningless, so it is not recommended.
