Manually copying all authentication headers into the downloading scripts would be too cumbersome. It allowed to download both m3u8 playlists with TS chunks lists and actual video and audio streams into mp4 files via a click of button while correctly preserving authentication headers. The resulting separate video and audio files can be merged with ffmpeg :. Tried Video DownloadHelper Chrome extension too, but it didn't work for me. While this shouldn't have ever been asked on SO and got through the vetting processing in the first place, I have no idea After exploring basically all of the options presented here, it turns out the simplest is often the best.
Next, after you have got your. I tried running it from a locally saved m4u8 file, and it didn't work, because the ffmpeg download procedure downloads the chunks which are relative to the URL, so make sure you use the website url. Many websites package their videos as multiple Transport Stream files. If you wanted to output the full length video you would need to download all. The assembling can easily be done using the FFmpeg command line tool. Once all. If you already know the url of the.
Then the following command downloads all the. Copy and paste one of the. Remove the identifying number of the. That should bring up the video file in your browser as usual. I also found it helpful to sort by waterfall in the network tab of chrome. This will sort by the time the files are downloaded, so when you are streaming a video the most recently downloaded parts will be at the top, making it easy to find the.
I came up with an efficient parralelized one-line that concatenate a sequence of. That's it! Then "one on one" and download it similar to video stream.
This software can download from any site in this format. Even this software can change the ts file format. You only need to change the format when downloading.

If you serve your videos from the same domain as the video player, there are no additional steps for you to do.
This presents a bit of a problem. If you request a resource a file from a different domain, you need permission to do so; it violates the same-origin policy that browsers enforce. Cross-origin resource sharing CORS is a mechanism that allows user agents to request permission to access resources that reside on a different server.
In this instance, you need to grant permission to the player to allow it to access to the video s in the S3 bucket.
By default, the configuration file allows access from anywhere. If I wanted to restrict access to the videos to this domain, I would modify the CORS configuration to look like this:.
You can do this by modifying the bucket policy. You could include the check in the allowed action but I prefer to use an explicit deny because it overrides any allows. However, bear in mind that the check can be circumvented because the referrer header can be spoofed. The solution is to tell the player to use the Media Source Extensions if the platform supports it for HLS playback instead of playing it natively.
You can do this with VideoJS by setting the overrideNative property to true. The referrer header will now be included in the requests so access to the video will no longer be blocked on Chrome Mobile.
This indicates to the player that each video segment is part of a larger resource. With the current configuration, any requests for the video file main.
Modify the CORS configuration file so it looks like this:. Amazon S3 is a cost effective solution for storing videos as video files can take up a lot of space. Check out the S3 documentation for more information. The thing you may want to check is latency: the time it takes to copy the segments from the origin to the bucket.
You may want to consider using CloudFront as well. Thank you simon, But we observed delays in response and the number of requests per second concurrent sessions only supporting. You are right, there are limits to how many requests an S3 bucket can serve. More info here. What makes this extra horrific is that if you log into Windows using an MSA account , the bad guy gets both your global userinfo AND a hash he can try to crack.
Beyond the data leakage risks related to remote file retrieval, other vulnerabilities related to opening local files also exist. Navigating to a local file might result in that file opening in a handler application in a dangerous or unexpected way. The Same Origin Policy for file URLs is poorly defined and inconsistent across browsers, which can result in security problems. Unfortunately, the extension API chrome.
JavaScript that calls window. Similarly, the Enable Local File Links extension simply adds a click event listener to every page loaded in the browser. But this extension will not help if the page attempts to use JavaScript to navigate to a file URI, and it exposes you to the security risks described above. This scenario does not accommodate all scenarios, but allows you to configure Edge to behave more like Internet Explorer did.
Raymond Chen explores this in Subtle ways your program can be Internet-facing. In an enterprise, the expectation is that the Organization will block outbound SMB at the firewall. It is very powerful and can even handle cookies, forms and ssl. However it can also be used for some very simple tasks that you will find useful. At its most basic you can use cURL to download a file from a remote server.
To download the homepage of example. It will, however, try other protocols as well and it can intelligently guess which protocol to use if hints are given. For instance, if you use curl ftp. If you want to give the downloaded file a different name you would use the -o option. For example. Quite often when learning curl you will either get an unexpected output or no output at all.
The -v option is very useful in these situations. The -v option displays all the information in the request sent to the remote server and the response it receives.
