Recording Movie From Video Card?

Default 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?

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.

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).

+--- Wireshark taps here.

I use a Video screen capture like::

CamStudio Recorder

Per Hot-Text:

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.

VLC is all running it Third Party
Ping-in Drives in the background 24/7
that F-Up all payers capture and playbacks

Turn off all Third Party Ping-in Drives
Audio Decoder and Video Decoder
Configuration

For Windows say thank you
for the Driver
but I need no help hand
in Configuration the Drives
by Essentials Codec Pack

do not put it in VLC in full screen
Set CamStudio to (Region)
Turn off all Third Party Ping-in Drives

5 min capture can be up to 2gb avi
Set CamStudio to it on Video Decoder
in it do not have it in Video Options
if you do not have the Drive go back to the website
and Get the CamStudio pug-in

But always Remember the that your
Third Party Ping-in Drives will f-Up
Audio Decoder and Video Decoder


I tried it on a couple of YouTube clips playing in a window and it

For YouTube MP4 files clips capture
I use RealPlayer plug-in for IE

Now I do not use RealPlayer and my Player
just the captured plug-in for clips files for IE

"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.

People below comment on CamStudio, which I've used
(legally) for smallish items. Now, device: it's
called a camera. I'll leave you to wrestle with your
conscience. For proof of concept, I went to Firefox
just now and recorded a news video -- looks fine, on
my camera anyway

CANDIDATE FOR A PULLET SURPRISE

I have a spelling checker.
It came with my PC.
It plane lee marks four my revue
Miss steaks aye can knot sea.
Eye ran this poem threw it,
Your sure reel glad two no.
Its vary polished inn it's weigh.
My checker tolled me sew.

A checker is a bless sing,
It freeze yew lodes of thyme.
It helps me right awl stiles two reed,
And aides me when aye rime.
Each frays come posed up on my screen
Eye trussed too bee a joule.
The checker pours o'er every word
To cheque sum spelling rule.
Bee fore a veiling checkers
Hour spelling mite decline,

And if we're lacks oar have a laps,
We wood bee maid too wine.
Butt now bee cause my spelling
Is checked with such grate flare,
Their are know faults with in my cite,
Of nun eye am a wear.
Now spelling does knot phase me,
It does knot bring a tier.

My pay purrs awl due glad den
With wrapped words fare as hear.
To rite with care is quite a feet
Of witch won should bee proud,
And wee mussed dew the best wee can,
Sew flaws are knot aloud.

Sow ewe can sea why aye dew prays
Such soft wear four pea seas,
And why eye brake in two averse
Buy righting want too pleas.
