transcoding raw dumps

[porte64]

Hello !

Does anyone know what formats VLC "raw dumps" generate; does it depend on the input device/drivers (i am recording from a basic logitech webcam) ?
I did not manage to replay them with VLC by "opening the file". Neither did other tools like "ffmpeg -i movie.dump"
understand the format.

I selected the "raw dump" option with of view to:
- getting the most faithful movie possible (less frame skips ...) because the processor will not be overloaded by transcoding on-the-fly.
- have it in the "native format" (resolution, fps) also !

And was then hoping to:
- get information about the movie resolution and fps
- so as to transcode it with adequate options

I think this topic is likely to interest many users, as webcam are often very basic and VLC seems to offer, thanks to the "raw dump" option, the best way to get quality/faithful records.

Phil
