Hello all,
I have some Questions regarding the ffmpeg library. It would be great if
someone can help me out. Below are my questions, if I am missing something
please let me know.

How can I do the following for video in YUV color space or which files in
the ffmpeg libraries should I look into to:

1> Display only the Y (luminance component) and zero out the chrominance
values (i,e. U = V = 0) ----- grayscale video.
2> Display Y and U (excluding V)
3> Display U and V (excluding Y)

The goal is to reduce the video bit rate with respect to the Wireless bit
rate available. I wanted to dynamically change the color informations in the
video, such as from color to gray scale and vice versa, so that there's a
smooth transition.
Basically I was working on a project using ffmpeg library, which captures
video from a camera interface and stream video to a mobile user wirelessly.
The user basically interact with the camera using a web browser to see the
video.
I used H.263 encoding for the video frames captured from the camera
interface at variable frames per second and quantization level depending on
the wireless available bit rate and pipe it to a server
which was running the ffserver process(the streaming server). The container
format used was .flv format. And the user basically opens the http URL and
can see the video on the flash web player.

Thanks
