May 11, 2017 The PS4 has an option to turn it off, so you can capture games, but netflix, youtube, hulu, and any other video app will block the capture card, with no way to launch these apps with HDCP turned off. May 03, 2020 I just wanted to report that the currently available (on Amazon UK) Wingoneer 2 Port HDMI Audio Video v1.3b 1080p 3D Splitter for HD TV PS3 PS4 Blu-ray 1 in 2out (UK Plug) did NOT strip HDCP 1.3/1.4 and allow capture despite some reports that earlier 2014-2016 versions of this splitter did strip it. At least it did not work for me in the US.

FAQ Search Memberlist Usergroups Register. Nov 15, 2019 HDCP is relevant when you use a digital HDMI or DVI cable.If every product using these cables supports HDCP, then you shouldn't encounter any problems. HDCP is designed to prevent theft of digital content, which is another way of saying illicit recording.As a result, the HDCP standard limits how many components you can connect. HDCP is an anti-piracy protocol built right into the HDMI cable standard, but it doesn’t actually work very well, and breaks the viewing experience. Read on as we explain how HDCP works, why it breaks your TV, and how you can fix it. Currently, the only success I have had at TRULY stripping HDCP has been when using the ViewHD HDMI 1×2 Splitter (Model# VHD-1X2MN3d) receiving signal from a Mac Mini, Output 1 on the splitter going to a TV Output 2 going to an AverMedia Live Gamer Portable.
It warms our hearts when the community gets together. [esar] needed to get a decrypted HDMI stream for his home theater system. A tip-off in the comments and a ton of good old-fashioned hacking resulted in a HDMI splitter converted into a full-featured HDMI decrypter. Here’s the story.
His amazing custom Ambilight clone got profiled here, and someone asked him in the comments if it worked when High-bandwidth Digital Content Protection (HDCP) is on. [esar] lamented that it didn’t. Hackaday readers to the rescue. [Alan Hightower] and [RoyTheReaper] pointed [esar] to the fact that HDMI splitters need to decrypt and re-encrypt the signal to pass it on, and pointed him to a trick to knock out the on-board microcontroller. [esar] took off from there.
Unfortunately, taking the micro out of the picture messed with a lot of other HDMI functionality. So [esar] started digging in the datasheets for the HDMI splitter chip, looking for registers relevant to the re-encryption. If he could get in between the microcontroller and the splitter chip on the I2C bus and disable the re-encryption, he’d be set.

If you’re at all interested in I2C hacking or abusing HDMI splitters, you need to read his post because he details all of the tribulations and triumphs. He first tries just brute-forcing the I2C by overwriting a 1 bit with a 0. This (correctly) signals the micro that there’s been a conflict on the bus, so it re-sends the command again. Dead end.

He then found another signal that the receiver could use say that it wasn’t decrypting. He tried sending this continuously to the splitter so that it would stop encrypting. That worked, but only for one channel, some of the time. It turns out that his code was taking too long in his bit-banged I2C code. He fixes this up and all is well? Well, 90% of the way there.

To hammer down the last 10% of the functionality, [esar] buys a couple more splitters, experiments around with another splitter chipset that works with 3D, and solders some more wires to enable the Audio Return Channel. And after a ton of well-documented hard work, he wins in the end.
