Apa itu cache browser?
Saat kami mengunjungi halaman di browser seperti Chrome, Safari, Tepian, Firefox, semua gambar, video, CSS, Javascript dan sumber daya lain yang digunakan pada halaman tersebut akan di-buffer dan disimpan sementara di lokasi tertentu pada perangkat kami. Sedemikian rupa, akses kami selanjutnya ke halaman itu akan jauh lebih lancar dan lebih cepat karena konten yang di-cache sebelumnya akan dimuat langsung dari folder cache, bukan dari server situs web lagi. Mekanisme ini menghemat waktu buffer sumber daya, minimizes bandwidth consumption and brings performance gains so as to give the Internet surfing a snappier experience.

How to save downloaded videos from cache of browser?
Here, we’ll take Chrome as an example to show the steps to extract videos from Chrome cache files.
- Open the page that contains the target video that you want to download.
- Play the video and wait until the video is completely buffered.
- Locate the cache directory.
- Find the videos files by sorting the pile of cache files by size since the larger ones are usually video files.
- Rename the files and add the .flv or .mp4 extension.
Now the videos can be played with a video player such as VLC player, PlayerFab Dan UniConverter Player.
Though this method is 100% free and we don’t need to install or use any extra software or plugin on our device, it’s still difficult to extract videos from the browser cache especially for novices since there are lots of disadvantages:
- The file names in the cache folder are obscured. It’s hard to identify videos files even through file size.
- The file extensions of the videos cached from different sources may vary so that we might need to try multiple possible file extensions for one file.
- Previously cached videos may have to make space for newer files.
- Large files may not be cached due to limited storage for the browser.
- The size of storage space available for cache files may be limited in some browsers and devices.
- Some videos may be cached partially.
- Some cached videos such as flash videos will be removed once the browser is closed.
- Some sites may use encryption technologies to prevent videos from being downloaded.
- Videos that have never been loaded in the browser won’t appear in the cache.
How to extract buffered videos from browser cache with VideoCacheView
When we find it’s hard to distinguish target videos files from a pile of cache files, we should leave professional things to professional tools. The tool VideoCacheView can solve the problem easily and perfectly.
VideoCacheView is a free and open-source cache viewer utility that is capable of scanning the entire cache of Internet Explorer, Mozilla-based Web browsers (Including Firefox), Opera, and Chrome within seconds, then extracting videos from cache easily and saving to local disk freely for future offline playback.
With VideoCacheView, it’s easy to save downloaded videos in browser cache or temporary folder as playable files that video players can recognize.
Follow the steps as below:
- Download VideoCacheView Dan GPAC, then run VideoCacheView;
- Wait 5 to 30 seconds until VideoCacheView finishes scanning;
- Play the listed videos with the default media player of your system or judge the target videos with the listed parameters (such as Download URL, Title, Browser, Last Accessed Data and File Size) to find the videos that you are trying to download.
- Save the wanted video to your video library.
kelebihan:
- No additional DLL files or installation process is required to save downloaded videos from browser cache or temporary.
- The scanning usually finishes in 5 to 30 detik.
Kontra:
- Not all the found videos show data in the Title column, it’s still difficult to find the video that you are trying to download.
- VideoCacheView only has Windows versions. It works on Windows 10 or earlier versions.
- Safari cache is not supported by VideoCacheView.
- It not the default option to load videos from Internet Explorer 10/11. You may have to check the box beside the option manually if it’s needed.
- You might need to turn to a video converter to transcode the output videos to the most popular MP4 format.
- The saved videos may get corrupt if the browser keeps running when you are extracting videos from the cache.
- In Windows 7 with User Account Control enabled, you may have to run VideoCacheView as administrator to saving downloaded videos from “Temporary Folder”.
- Videos streamed via the Streaming Microsoft Media Server (MMS) protocol, (whose URL starts with mms://, mmst:// or http:// and ends with .asf, .wmv or .asx) cannot be extracted from browser cache with this cache extractor.
Kiat:
- The quality of the video extracted from the cache files depends on the resolution you choose when playing the video in your browser.
- In Firefox, cache files won’t be saved to the local cache folder until the browser is closed. Karena itu, if you need to extract videos from Firefox with the cache viewer, you may have to close all the tabs and windows of Firefox.
- Though the video loaded in Firefox won’t appear in the cache folder when Firefox is still running, VideoCacheView can still extract the video from the “Temporary Folder” entry alternatively as long as the browser tab that buffered the video has not been closed.
- Umumnya, you don’t have to run VideoCacheView “Run As Administrator” to extract videos from browser cache.
- If you don’t want to get an incomplete or corrupt video, you should let the video be fully buffered.
- Make sure you have enough space on your hard drive since there is possibility that the extracted videos might be partial or corrupt due to lack of enough storage space.
- Presently, 2 WebM streams (one video stream and one audio stream) are used in each video we play on YouTube, VideoCacheView will extract the 2 streams separately so that you might have to merge the video and audio streams using a third-party video editor or video transcoder.
- In browsers that use MP4 streams or have WebM feature disabled, VideoCacheView will also save the audio and video streams of YouTube videos separately. Namun, if the open-source software package: GPAC has been installed, VideoCacheView automatically detects it and uses MP4Box installed as a part of GPAC package to merge the 2 mp4 streams into a single mp4 file.
- To disable WebM streams in Firefox, visit “about:config” in the address bar, change the “media.webm.enabled” value to false.
- Although Safari is not in the support list of VideoCacheView, you can download SafariCacheView from the same developer to read and parse cache file of Safari Web browser (cache.db).
- SafariCacheView only works on Windows 7 and previous versions. If you want to find the videos in the Safari cache on macOS, transfer the cache.db file to Windows.
Final Words:
All in all, you can extract downloaded videos from the cache files of Chrome, Firefox, Tepian, Internet Explorer, Safari and Opera directly or with the help of VideoCacheView or SafariCacheView. Namun, there are still lots of challenges to face especially:
- The locations of cached files for different browsers and browser versions on different system platforms and OS versions may vary considerably so that it becomes difficult to find the temporarily downloaded files.
- Even with the help of VideoCacheView, it’s hard to distinguish videos files from hundreds of files with obscure or random file names while without files extensions.
- The found buffered videos might be corrupted or clips of the original videos due to all kinds of unexpected or unknown reasons.
- To get the videos fully cached in your local disk, you might need to wait until the video are completely loaded, which is troublesome and usually takes much time.
- When using VideoCacheView to extract downloaded videos from Web pages, you might sometimes still need to play the videos one by one to recognize the video you are looking for, Anda mungkin terkadang menemukan bahwa semua ukuran file adalah nol.
Mengingat kekurangan di atas dalam menyimpan video yang diunduh dari cache dengan atau tanpa VideoCacheView, profesional tetapi mudah digunakan pengunduh video Suka Streamfab Dan Pengelola Unduhan Internet (IDM) sangat dianjurkan.
