You may get a few seconds of video and sound "before" the HDMI port shuts down. like right after a commercial and the program starts. The Copy protection enforced by HDCP over HDMI will restrict or shutdown the connection as soon as Copy protected content begins to play. To answer your direct question (Is there anything that works with HDMI that records losslessly?) yes there is, several things. You might even have a 480i S-Video connection you could capture from. so it could squeeze that content out those connections. Some Cable and Sat boxes would even "downscale" higher resolution content. but they do not support as high a resolution or frame rate because those connections can not carry higher resolutions and frame rates as HDMI can. those generally do not have as much trouble. some people called it RGB or the YUV cables. Simply HDMI ports are pure hell at getting capture content signals to work reliably.Ĭable and SAT boxes at one time had an alternative to HDMI for output. but then you have to answer questions about whether you should be doing that. and then didn't as it was abused by broadcasters and content producers. but more and more even the commercials are 'protected content' and the port shuts down. "Un" -intuitively, cable boxes may briefly or for short periods of time, pass content over HDMI to a capture device, like for commercials or unprotected content. using an HDMI connection to, your cable boxįirst you need to be aware that most HDMI content output by a cable box will have problems if HDCP is involved. You have provided two new additional pieces of information indirectly

it can loose data or sync with the capture process and you get problemsĪ time base corrector or a frame sync can "buffer" and give a PC "time" to catch up. When a PC is in charge of every aspect of the capture. it delivers an uncompressed pre-captured product to the PC after its fully captured. it delivers a compressed pre-captured product to the PC after its fully captured. The only alternative is to "out source" the capture to an external 'box' like a hardware compression device that only delivers the finished digitized product on demand when copying the capture to the PC. and they share the hard drive, or dvd drive
It is why a DVD recorder has two CPU's, running two different operating systems one for the RTOS (non-interruptable - real time operating system), one for the user interface.

For example, if you used your webcam in a Facebook chat using Google Chrome, Google Chrome will be listed in this section.Windows is a multi-tasking operating system with pre-emptive interruption of tasks (aka 'programs') the device drivers are supposed to "interrupt" the interrupter to make sure the device buffers never over-run and loose incoming and outgoing communications, unfortunately that happens The list of apps under this section represents the apps that you've permitted to use the camera in the past.If this switch is not on, click it to turn it on now. Scroll down to the "Allow desktop apps to access your camera" header.The slider below "Allow apps to access your camera" should be set to the On position.Look at the right panel-if you see "Camera access for this device is off" at the top of the window, click the Change button and slide the switch to the On position.Scroll down the left column and select Camera under "App Permissions.".Open the Start menu and click the Settings gear.
To adjust your permissions: X Research source Your webcam's screen may appear black in the app you're using if the app doesn't have permission to access the cam.
