I'm curious as to how a cop would show that OP had violated this subsection of 22101:
(d) When official traffic control devices are placed as required in subdivisions (b) or (c), it shall be unlawful for any driver of a vehicle to disobey the directions of such official traffic control devices.
"Official" left-turn "traffic control device" was red. At no point did OP (1) move into the intersection & (2) manifest left-turn movement.
Perhaps he violated some other CVC (such as "improper use of a left-turn lane"). But he's NOT charged with a "lane violation." Sub-section (d) is exclusively about "official traffic control devices." And that sub-section does NOT define a "traffic lane" as an "official traffic control device." Although OP most likely committed a CVC infraction, he doesn't appear to have violated the CVC with which he's charged.
******EDIT******
Reviewed OP's video again. With his right signal blinking, OP moved from left-turn lane to "straight ahead" lane, when significant room existed between both his vehicle & one behind him. So he did NOT violate CVC 22107 (Unsafe Lane Change).
https://leginfo.legislature.ca.gov/f...ctionNum=22107.No person shall turn a vehicle from a direct course or move right or left upon a roadway until such movement can be made with reasonable safety and then only after the giving of an appropriate signal in the manner provided in this chapter in the event any other vehicle may be affected by the movement.
