in your opinion what is the best component /wrapper for camera grabbing to file using VP8/H264 (web) codecs?

Maybe you should tell us more about the intended application.

In the past, I have used a lib from michael@grizzlymotion.com. The units are VFrames.pas and VSamples.pas. I don't remember where I found it but a little search show those two links of interest.

Using this code, I get raw frames from the camera, then I use FFMpeg tool to compress rawframes with the required codec to produce anyone of the ffmpeg video format. I invoke FFMpeg command line, feeding it with a pipe. My Delphi program write to the pipe and FFMpeg read the pipe.

FFMpeg is available from https://ffmpeg.org/download.html You do need the source code. Prebuild executable is enough since you'll pipe the frames into the utility.

To pipe data, I use my own code. I wrote a blog article: http://francois-piette.blogspot.com/2013/04/inter-process-communication-using-pipes.html
