BAN: Chrome Extension Stream Recorder: Scrap 2nd.

Revival!

At the time of writing this article, it can be installed from the Chrome Web Store, so it seems that the discussion with Google has ended and the concerns have been cleared.

The version when the distribution was stopped is v1.1.2, but the version after the distribution is restarted is v1.2.0 (2019/09/13).

The differences are as follows.

version 1.2.0
HLS-Encryption is a disabled version

The new version v1.2.0 cannot download content protection media.

・・・ TVer cannot be downloaded.

Streaming media

Stream Recorder is a Google Chrome extension that allows you to save streaming videos uploaded to your website with the extension -.MP4.

Only HLS method is supported.

The HLS method consists of a file (-.m3u8) that describes the path (URL) where the actual movie file is stored, and a video file (-.TS).

HLS: HTTP Live Streaming, -.m3u8

Videos other than HLS are supported by Tokyo Loader for Chrome developed by the same author. (See related article)

For how to use it, read the next section.

How to use "Stream Recorder"

When you install the stream recorder, an icon will be displayed on the toolbar of Chrome.

If the icon changes to a large red circle when playing a website video, the video is delivered in HLS format.

Small red circle	Big red circle

Download procedure

Simply click on the large red circle icon on the Chrome toolbar and the stream recorder will automatically perform the download and merge.

The divided multiple TS files are saved in the working folder of the stream recorder.

When all TS files have been downloaded, the stream recorder will combine the files, convert them to .MP4 format, and move them to the specified folder.

Click the large red circle icon
New tab opens and download starts
Save split files (-.ts) to working folder sequentially
After acquiring all TS files, combine them in the download order
Extension-convert to .MP4
Move to Chrome download folder
End

Software information

Date confirmed:
Extension	Stream recorder
Functional overview	* Quoted from Chrome Web Store You can save streaming video distributed by HLS (HTTP Live Streaming) as mp4. Also, because it has a unique video capture function, it is possible to directly record videos that cannot be saved with normal download apps. Therefore, it can be widely used not only on general video sites but also on live distribution sites such as Twitch and Mixer.
version	1.2.0
Release date	September 13, 2019

Summary

The stream recorder has been revived, but its functions are limited.

Banned Version: Version 1.1.2
Revival version: Version 1.2.0
Deleted function: HLS-Encryption

HLS-Encryption is implemented in Version 1.1.2.

Since the stream recorder had excluded YouTube from the beginning, was it a quick revival?

If the stream recorder is not working properly, disabling the ad blocker may work properly.

Files other than streaming media can be downloaded with Tokyo Loader.

Please note that it is prohibited by law in Japan to download videos uploaded without the permission of the copyright holder while knowing them.

declarativeNetRequest API

2019/09/23

Half a year later, the stream recorder will stop working! ?

The operation screen of the stream recorder states that "it may stop working when a new operating environment for extensions is introduced in Chrome".

The new operating environment is likely to refer to the [declarativeNetRequest API] that Google is considering changing the specifications.

The declarativeNetRequest API is a new specification that Google is considering as a way to stop runaway extensions.

(2019.09.14) Today, due to sudden approval by the web store, an unexpected update was carried out.

This version does not support HLS encryption, so some sites will not be able to download it. And for now for now, I'm sorry for the inconvenience.

(News) This summer, Google Chrome Canary will introduce a new operating environment for extensions on a trial basis. Finally, it is possible that this extension will not be available at the time when you move to this new operating environment (which is said to be after 6 months).
