Recording Movie From Video Card?
If I am streaming a movie, it seems logical that an unencrypted
audio/video stream must exist somewhere between the PC's video card and the monitor. Is there any application/device that would enable capture of that stream? -- Pete Cresswell |

Is there any application/device that would enable capture of that stream? HDMI is protected by HDCP. Using an HDMI capture card, you see "colored snow", if you attempt to snoop on HDCP. An HDMI capture card is not allowed to possess HDCP keys. (Only pirates own such cards, as HDCP was busted some time ago.) If you go VGA, your odds are better. Up to some resolution, the OS may not even attempt to "fuzzify" your movie playback. The limit is probably 1080i60, in terms of defining a bandwidth limit. I notice some newer cards advertise 1080p30, which uses the same bandwidth. Somehow, the capture card industry has decoded the DMCA legislation, as allowing up to 1080p30 or 1080i60 as "the limit" on capture. Example of a capture card. Slightly dishonest advertising. http://www.newegg.com/Product/Produc...82E16815158317 Real limit revealed here. It has the same limit as the others. http://www.startech.com/AV/Converter...onent~PEXHDCAP "Maximum Digital Resolutions 1080p30" I notice too, that one of the Avermedia cards has disappeared, to be replaced by something that promises "streaming". So who knows how long the Startech card will exist, without chasing such a useless option. (Some people just want capture of their screen... Even for educational purposes, like How-To tutorials. Not all capture applications are about "stealing content".) The original device using the Analog Devices front end, was the BlackMagic Intensity Pro. It may have had some additional options, for loop thru. Don't remember the details now. With some of the cheaper cards, they only have inputs, and then you need an OS and driver that still supports "video mirroring" to get your movie. Another downside of this card, is the capture options are quirky. They did their own MJPEG compressor of some sort. The design would have been nicer, with a wider bandwidth PCI Express slot connection. http://www.amazon.com/Blackmagic-Des...+intensity+pro BlackMagic also make a USB3 version (tray-style box), but that requires a "true" USB3 connector, not a half-bandwidth one that exists on many older motherboards. The BlackMagic USB3 software, even tests for this, and denies capture if your USB3 isn't fast enough. The reference here to "X58 or better", is a veiled warning about inferior USB3 implementations. I have more details if you want them. http://www.amazon.com/Blackmagic-Des...intensity+usb3 So, there are solutions, but kinda half-assed, and it's all the fault of DMCA legislation. That's what seems to peg the upper limits of resolution. To stop VGA copying, some OS/software combinations would use a "fuzzy" option, to spoil both the ability to watch the movie, and the ability to copy it "pixel perfect". For the price though, one of those makes a nice toy. A lot cheaper than some of the $3000 boxes they sold ten years ago, that couldn't do nearly as much as the cards above can. Paul |

Is there any application/device that would enable capture of that stream? I seem to have mis-read your post. If you are "serving" streamed content, you can stream a copy to yourself if you want. Say your server can support ten users. You could set up a client computer, and connect as one of the ten users. And make your copy that way. My previous answer, I was assuming you could see the movie on your computer monitor. In which case, a capture card can be used to capture what is on the monitor. That covers cases such as watching Flash movies which have their own protection mechanisms. If the source was an IP camera, you could use Wireahark to collect all the packets. And store those as a .pcap file for later analysis. Then, your viewing would not be real time, depending on how often you collect the Wireshark file for analysis. And that only works, if the IP camera stream is not encrypted. If the stream is encrypted (and it should be), then tapping the packets isn't going to work very well. The connection to the client should be encrypted as well (like, https). IP_Camera ------- Streaming_Server ------ Clients ^ | +--- Wireshark taps here. Paul |

I use a Video screen capture like:: CamStudio Recorder From here http://sourceforge.net/projects/camstudio/ I'm fooling around with it, but not having much luck capturing movies from existing .MP4 files played on VLC Media Player. Seems to not capture anything when the player takes over the whole screen. I tried it on a couple of YouTube clips playing in a window and it captured - but at a very low frame rate. I'm guessing the second issue is my setup parms. The full-screen thing sounds like an inerrant limitation of the app to me. ?? -- Pete Cresswell |

"Plug-in drivers" perhaps ??? ******* I tried CamStudio here, and the "real" recording rate on my Core2 Duo 3GHz, was 7FPS. So I'm not going to be stealing any movies with that program, any time soon. Not when I'm only getting about a quarter of the movie. Paul |
