GoPro Inc., a maker of wearable cameras that have fed a flood of YouTube videos, is laying the groundwork to go public.

The San Mateo, Calif., company said Friday it had submitted a confidential filing for an initial public offering with the Securities and Exchange Commission.

GoPro and its bankers are expected to begin pitching the deal to investors in the first half of this year, people familiar with the company's plans said. The deal will seek to raise roughly $400 million, though the final amount has yet to be decided, they said.

The deal's pricing also is in flux, but the company will aim for a stock-market valuation well above the $2.3 billion it was pegged at in a 2012 fundraising round, these people said.

GoPro's offering will be led by J.P. Morgan Chase & Co., Citigroup Inc., and Barclays PLC, they added.
