Stream Recorder

(Important!) Closing this tab will result with the loss of the downloaded data!
We are not responsible for the media downloaded by users. We suggest checking the copyright of it.

(Note) With the update to Google Chrome 85, older versions of the Stream Recorder will no longer work. Please be sure to install the latest version of the extension. Also, since this update has a significant impact on the extension, we are planning to make some fixes to improve performance in the near future. We apologize for the inconvenience. (Note2) The current version does not support HLS-encryption. Therefore, please note that downloading HLS may be rejected at some sites. (Note3) Google is experimenting with a new extension working environment called "Chrome Manifest v3." At some point in 2020, all extensions will move to this new environment, but we cannot guarantee that the Stream Recorder will work in that environment at this time. We will keep you updated.

How to Use the Stream Recorder

Stream Recorder has two main operation modes - Normal and Capture.
For the general HLS (HTTP Live Streaming), downloading the video directly is possible only if the video index can be detected. If the index is detected, the action button will become active and therefore the direct download - possible.
Even if the video index cannot not be detected, if it is HLS streaming, the video can be saved by using the video capture mode. In such cases, please press the action button on the video site or click the "Capture Mode" button at the upper right of the browser.

LIVENormal mode ( Live )
     You can close the tab from where the video is being recorded from. During the live streaming, if there will be problems with the network, the video may be cut midway and saved until that point. Pressing the browser's reload button discards the previous data and a new recording will start from the beginning.

HLSNormal mode ( Archive )
     You can close the tab from where the video is being recorded from. For some videos, you can also use the Boost function. By pressing the browser's reload button, you can restart the download from the beginning.

RECCapture mode
     When using the Capture mode, as the video is recorded as it's playing, it is necessary to leave the video playing. Also depending on the site, some streaming types may not be captured - you will have to try pressing the action button to confirm this.
     *NOTE*
     If during recording the extension receives a connection break notification from the server, the video will be split into multiple files and a new recording sequence will start. This situation may occur with an unstable internet connection, when the browser tab is inactive, or with the poor live streamer's connection. Also, the file may be split if the audio or video are not in a ceaseless state.

If problems persist, it may be that the video is delivered in a format not supported by the extension - in such cases please try using other video downloading extension as a substitute.

Specification

Downloaded audio and video data is converted to mp4 as it is with the same quality without re-encoding.
This conversion is done inside the extension, without the use of an external server.
Only when there is enough free memory to use (set in Chrome with a limit up 2 GB), it will be preferentially used for caching.
Stream Recorder is a tool for downloading and storing videos by using a common and well-known methods.
We are not related to, nor do any special processing, for 3rd party websites.

Unsupported videos

We are not supporting (and will not support) video downloading streamed with Flash (such as RTMP).
We do not support downloading DRM-protected videos neither.
For videos streamed via WebRTC, we will add support in the case of a high demand. This also applies to the case of Media Source Extensions with WebM.
Since we are not supporting videos longer than 13 hours and 15 minutes, please divide the download into smaller chunks.

Boost

For HLS archive video downloading, you may be able to download the video faster through parallel processing.
However, there may be cases when the downloading speed will be reduced by this function.
Please pay attention to the following points and use the function carefully to avoid overloading the server.

In what situations may downloading become slow?
     - If downloading is already sufficiently fast without boosting
     - If your cable is slow
     - If your CPU is slow
     - When the server itself limits the bandwidth or does not allow parallel downloads
     - When connecting to the same server exceeds the maximum number of 6 connections

Currently the number of parallels is limited to 3.
It is half of the number of concurrent accesses the browser permits and we have determined that 3 should be at the acceptable level.

TIPS

Please use it at your own risk.

How to clear the settings
     All settings are stored in the localStorage of this domain.
     You can clear the settings by running localStorage.clear() on the Developer Console.

How to download the video from the middle
     You can assign "start" and "stop" as parameters of the URL of this page.
     Please use it when splitting and downloading exceptionally long videos.
     Note that this parameter is valid only when video and audio are stored in the same .ts file.
          (Example) .../rec.html?start=30

How to specify parallel number of downloads in the Boost
     The default parallel number is 3, but you can specify a number from 1 to 6 with the Developer Console.
          (Example) localStorage.parallel = 3

Troubleshooting

In the case of an error occurring, you can retry after a while.
If you are continuously getting the same error, please refer to the guide below.

403
     Access to the server has been denied.
     There may be various reasons:
     The server may be doing a strict check of the access to the file (like specific timing etc.).
     When you are playing a video in the original tab and you may not allowed to access the video in another.
In the case of an unpredictable error please don't hesitate to contact us.

404
     The target file does not exist.
     If you are always getting errors during the download, there may be a problem with the server.

408
     Connection timeout.
     Please check your own connection condition and retry the download at a different time.

Failed to fetch
     Cannot connect to the server.
     It may be due to the
          - Network instability
          - The server is down
          - Blocked because of the ad blockers etc. (especially if the error always occurs in the same place)

Live recording stops in the middle
     We had signals from the users, that if you don't keep the original tab with the video open, the download fails.
     Also we've heard about cases, where the video's index file changes in the middle. We will take care of this problem soon.
