Re: capture live video in yuv planar format

From: "Huey"

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.
