Video DownloadHelper 7 for
Chrome
Changes from 7.1.2
Features
- YouTube bulk download: it is now possible to mouse-select a part of a YouTube page and request the download of all the videos that are linked from from the selected section. This is feature was existing in VDH6 but was limited to unsigned videos. You can also now launch a Download & Convert bulk operation, allowing for instance to retrieve a large number of MP3 files in a few clicks. Try it: from a YouTube page, try CTRL-A to select all the page, then click the Video DownloadHelper toolbar button
- Smartnaming is back: you can now again specify for given sites where in the page to get the video file name from, or choose an obfuscated file name for discretion. Unlike VDH6, the new Smartnaming allows full XPath expressions to generate accurate video names. Try it: from a page containing a video, right-click and pick Video DownloadHelper > Smart Naming Rule
- Conversion rules: it is possible again to define per-domain and/or per extension conversion rules, so that downloaded files are automatically converted in background. Try it: open Video DownloadHelper settings and choose Conversion Rules in the dropdown menu
- Variant preferences editing: as with VDH6, you can now reorder the variant qualities you want to appear at the top of the list. Try it: open Video DownloadHelper settings and choose Video Qualities in the dropdown menu. Use Drag & Drop to reorder the variant preferences
- VDH commands from Firefox Tools menu: this is an opt-in feature, it has to be enabled from VDH settings > Appearance
Fixes
- Fixed aggregating YouTube videos that could, in certain cases failed with error Invalid data
- Fixed clicking through YouTube playlist could show previous video title in the download menu
- Fixed handling misformed MP2T frames on some HLS streams
- Updated locales
Reminder about Video DownloadHelper 7 and Firefox 57
Some users still complain about some feature regressions in Video DownloadHelper 7 when compared to version 6, and the requirement to install a companion application in situations where this was not mandatory. So, we'll explain again what happened.
When Mozilla released Firefox 57 (a.k.a Firefox Quantum) on 11/14/2017, this came with a major change: the original API (i.e the way an add-on "lives" within the browser) was removed and replaced by a new one called WebExtensions as it is in Chrome. Unfortunately this new interface is very restricted compared to the previous one and lacks a number of services that are required for Video DownloadHelper to do the job.
Many Firefox add-on authors decided to give up and not make the move to WebExtensions. We made an other choice and decided to continue providing the service to our users by whatever mean was technically possible, rewriting almost entirely our extension.
WebExtensions offers a clean way to run dedicated external applications and communicate with them in background. We used this to create a companion app that provides the now missing services, mainly file manipulations and unrestricted downloads. We made this app open-source to ensure transparency, and it is now required to use it for some features like HLS downloads where it could previously be performed entirely from within the add-on.
Thank you for reading that far, you are an awesome person !
