Video capture support on Linux.
 
Would you like NVIDIA to offer Linux customers video capture support in their drivers? Currently the Linux drivers provide only support for video out, not capture for video in. Supporting both VIVO functionality in their drivers will improve the customer experience by offering tools already provided for Windows customers. This would allow such things as NLE (Non-Linear Editing) being possible. Also NVIDIA has an opportunity to reduce customer churn by providing this support before ATI does.

I don't own a VIVO based card but I'd like to see this be supported. NVIDIA can add this, as they have all the specs required to do so.

Probably just a big dream, like the FreeBSD/x86_64 drivers that don't exist.

YES! This would be very useful for me, particularly if it could capture into an
OpenGL texture.

kind of a silly poll, there are things I'd like more, but I don't see why anyone would want to vote "no".

I use a Hauppauge card for capture, works very nice on Linux, and seems to get along well enough with playing on my nVidia card.

I don't have a VIVO card, I can use my Leadtek WinFast TV200XP for video capture, but I vote yes.

Does nVidia have all needed specs to develop such driver or this is a secret of card manufacturers?

While Hauppauge WinTV-PVR cards are nice they certainly can't be compared to the encoding/decoding features that are available with NVIDIA cards such as the MSI NX7800GTX-VT2D512E which supports H.264 hardware assist, HDTV decoding up to 1920x1080 resolution, three dedicated video engines, etc.

Of course, "official" built-in capture support in the closed source driver would be great., but personally, I'd be content if nvidia just provided a way for the rivatv open source capture driver project to start working with the closed-source nvidia driver again. The rivatv project does support the video in on most nvidia cards out there, except the very newest models. Unfortunately, since the 6xxx series, you can only run it with the open source nv driver, which sucks.

I have a Gigabyte 6600 VIVO card and would love to be able to use it under Linux (the only OS I run)

Re: Video capture support on Linux.
 
The general idea sounds good: Capture support for nvidia hardware. However, I think this would somehow fall under the video4linux project. Surely any hardware support for Nvidia capture (Nvidia assisted / supported or not) would need some sort of relationship to this project. Perhaps the v4l guys already have this in the works, I would do some checking in this realm.

I would like to remind everyone that this poll / post is in regards to capture support for nvidia hardware, and not a poll for 'what card do you personally use for capture under linux'. I sure see a lot of “why on earth would you want to do that? You should just buy the xxxxx hardware I use because it works much better.” type responses on this forum.

Responses of these types do little to help the cause of this form: Better Nvidia hardware support for Linux/BSD.

this wouldnt be a problem if nvidia would allow access to the hardware for the video capture while its driver is loaded. this was never an issue in the past and v4l worked fine. the drivers block access to the card now.

Can a moderator please make this thread a sticky?

Re: Video capture support on Linux.
 
As I posted a few days ago in a similar thread, portions of the nvidia driver will be opened (i2c bus access will be possible using /proc) which in the end will allow rivatv to function.
