Re: capture live video in yuv planar format

I am able, quick enough, to save NTSC (720x480). But, I have problem with
720P and 1080i.

My system is a DELL 490 with dual 3 GHz Xeon CPU, 3GB Ram and SATA drive
(Seagate Barracuda 7200.10 SATA 3.0Gb/s 250-GB Hard Drive).

Do I need a SCSI or Raid disk for the task?

I am trying to save live video stream in yuv format. I
tried it with using only writing raw yuv data with CFile
but keep losing frames. Application using CFile is too
slow.

What resolution and frame rate? What CPU and HDD?

Uncompressed video is a lot of data, even YUV at QCIF
resolution (3.3 MB/sec) , and many systems simply can not
keep up, especially without specialized unbuffered and
overlapped I/O or if the volume is fragmented or used
concurrently.
