This converter comes from a well-known brand with good reviews. HDMI capture is a technology option like other alternative methods, it is a way to record HD video in real time.ġ. You should be able to send any content you want through a splitter to multiple TVs. In theory you shouldn’t have copy protection issues… in theory.

The splitter won’t convert the signal to 1080p just for that TV. An in-browser recorder more powerful than most desktop apps.Ī splitter will duplicate a signal and send it out through multiple HDMI cables.

so in this devices runs firmware that processes HDMI streams over an USB-C connector, however in USB protocol it implements an upstream-facing port, what a computer or laptop can not implement due to its hardware restrictions that implements a USB host or downstream-facing port. The inability to set a USB-C port into device mode or upstream-facing port mode is the reason why external adapters have to be usedĪn example for a USB-C device that is a USB peripheral or upstream-facing port mode is i.e. The linux USB-C kernel module is in and and it is defined as USB-C host or downstream-facing port only, so it is impossible to use it as HDMI sink or upstream-facing port and so it is impossible to use it as input and capture from it.

If you are not able to set your computer into device or peripheral mode you will not be able to capture HDMI signals over USB-C because of the USB protocolĬritical is the firmware and kernel module / driver of the USB-C port controller USB-C input or peripheral devices like displays are in device or peripheral mode. In a USB tree can only be one host and in most cases a computer is in this role as host. Types of ports are called Dual-Role-Data (DRD) ports, which was knownĪs USB On-The-Go in previous specification. Some, such as mobile phones, can takeĮither role depending on what kind is detected on the other end. Problematic is that in USB(-C) protocol a machine can either be aĭevices may be hosts (DFP: Downstream-facing port) or peripherals That raw pixel data can be transfered over USB-C in HDMI Alternate Mode should make it possible to capture a HDMI stream directly from USB-C, however there is a major drawback :

#Usb based hdmi video capture device dual monitors software#

When your software receives this stream, it doesn’t need to decode it,

#Usb based hdmi video capture device dual monitors full#

When itĪrrives on your computer, the CPU and/or GPU need to work toĭecompress this image, then re-encode it with your encoding settings.Īnd with this type of pre-compressed video, it’s never possible to getīack the full detail that was lost in compression.īy contrast, our AV.io family of HDMI capture cards send raw pixelĭata across to your computer over USB 3.0 (max transfer of 640 MB/s). Like H.264 or Motion JPG so it’s small enough to fit across a USB 2.0īus (a medium with a maximum data transfer rate of 60 MB/s). Other video capture solutions compress your video into a container This raw pixel data is also wrapped in USB Video Class protocol ( ) : There are active HDMI-to-USB video capture cards that convert the HDMI stream into a video format that is then transmitted over USB Video Class protocol or directly into raw pixel data. In this case there is no USB Video Device protocol ( HDMI is a different protocol ) and the situation is more complicated, see and What i do not completely understand is if you want to capture HDMI streams over USB-C via USB-C HDMI Alternate Mode ( ).

'webcam USB-C' however USB-C extends the functionality of the port by the Alternate Modes and so also uses different port controllers with different firmware and kernel modulesĪlt Mode is a functional extension of USB-C which enables the USB connection to carry non-USB signals. USB-C standard is the physical layout of the connector, it does not change the fundamental organizational structure of USB standard like its differentiation in device classes and so there are UVC devices with USB-C connector, search internet for i.e. HOW TO: Use VLC to capture video from your webcam to a file Mass Storage Device Class, Communication Device Class ( CDC ) and also USB Video Device Class ( UVC ) almost any modern camera device implements this UVC class and you can capture the stream of UVC devices with software like vlc USB protocol is organized in device classes, i.e.
