capturing a raw video

[msm_007]

Hi all,
I want to develop an application of real time coding raw video (.YUV) using H264 (x264) coder and I’ve got stuck in capturing the raw video (a single composite stream of Y, U and V components or 3 streams (one for each component) )

I have two satellite cards (skystart2 and pinnacle system HMVB), JVC camescop and Panasonic MD-1000 3CCD camera

I wondered if one of these devices offers raw video for capturing, if not could you plz tell me what kind of devices I can use for capturing a raw video
Thx a lot, MSM

I'm not sure what you intend to do.

SAT cards always capture the incoming stream as it is (slight changes are present however, but these concern the container and not the video/audio/teletext/etc. themselves). Actually for SAT cards the term capture is slightly misused, the very same way as it is for firewire cards. They transfer not capture.

What is a camescop? The very basic camcorder captures optical images onto a tape/card/HDD/DVD while it also outputs the image through its analog/digital outputs. Unless is a HD camcorder or a profi one, I'm afraid you have to accept composite and/or S-Video.

The Panny is a semipro camcorder, it features DV-out (see § above). I'm not sure it would output YUV, check the manual.

So you end with either AVI or DVB files, that you can easily convert into h.264 streams. How to do is here: ->:search:

This issue is a burning one for you, since you asked this 3 times...

I want to develop an application for real time video coding, for that I have to find a way to capt video for coding in real time
actually my application works well on off-line for raw yuv video (entire file stored on disk), for that I hope if I find a solution to capt in real time in yuv
