The RGB video comes in slices, that is, each buffer is part of a frame:
buffer != frame -> buffer < frame. Take into account that a buffer can contain
data from two consecutive frames because the frames are just concatenated one
after the other. Therefore, you MUST control the storage/transmission of the
frames because the video capture can be stopped at anytime, so it's likely
that the last frame won't be received entirely, so the current received bytes
MUST be discarded. For example:
Note: Rf1 means channel Red of a pixel in the frame 1.
... Rf1 Gf1 Bf1 Rf2 Gf2 Bf2 ...
| |-----------|-----------| |
