</div>Could you describe in some more detail what you want to do exactly?<br>
<br>
"Take a video" - from what source? Camera? What kind?<br>
<br>
When you say you want to "extract the luma and chroma components from<br>
the video into raw files", does that mean you just want to save the raw<br>
video frames to a file somehow, or do you want to access each frame in<br>
your application directly and then poke at the pixels (luma/chroma<br>
components) yourself? The appsink element might help with the latter.<br>
<br>
Cheers<br>
