Absolutely nothing from the devs.
How many times does Germania have to explain this to you? It is the way that the ITVX website makers have set up their site. The StreamFab developer can only start downloading after the hmac comes, and that is after the video has started.
The plugin has been broken for over a month and they do nothing. Fix the plugin! It doesn't work.
StreamFab doesn't use plugins. If you mean the ITVX module, that is the way it is, based on the unusual method that ITVX has chosen to use. The SF devs have no choice but to wait for the hmac to appear before the download begins. You'll just have to get used to it. Life is a bitch.
The software is expensive and needs updating. Taking peoples money and not offering fix's is an absolute scam.
You just joined the forum in July and this is your second post, both of which are complaints about the ITVX module. Assuming that you aren't foolish enough to use a cracked version of SF, you probably, recently, had 3 trial downloads before you bought the program and are within the 30-day return window. If you are not happy, quickly ask for a refund and go purchase a screen recorder program (although you'd then be in the same boat but worse since you'd have to not only wait for the video to start, you'd have to wait for it to finish) or let the Scene do the work for you. Let me fill you in on a little truism, in the course of using StreamFab, over time, you will feel like you are being ripped off by a scam hundreds of times. It is not always the devs fault. It is a product of the cat and mouse game. Streamers don't want you to download their shows. It violates their contracts with the show's producers. And, surprise, it is illegal to do by international law in most countries of the world. In the case of ITVX, I'm not so sure whether they are doing so to make life hard for the downloader. They have just chosen to give the authentication code AFTER the video has started rather than the more common, before. Deal with it whatever way you'd like best but stop whining here about something that you've been told can't be changed by the SF developers and is a product of ITVX's procedural methods.
