As speculation mounts of an imminent record-busting transfer from Barcelona to Paris Saint-Germain, Neymar's video appeared to be from the first class lounge at Dubai airport.
The 25-year-old forward, who was in Shanghai on Monday fulfilling a sponsor's engagement, also posted a photo with the caption in Portuguese: "Lunch at half-way".
In another video posted from an aeroplane, Neymar jokes around with an image messaging app that superimposed a Spanish flag and a small plane on his tee-shirt -- suggesting he is indeed headed home to Barcelona.
The decor in that video was identifiable as from an Emirates aeroplane.
Earlier reports claimed that he was headed from China to Doha, to meet PSG's Qatari owners and pass a medical before his reported 222-million-euro ($260 million) move from Barca.
But his being on an Emirates plane rules out Doha as a possible destination given the diplomatic crisis between Qatar and its Gulf neighbours.
Other reports had said the Barcelona forward could be headed directly to Paris after deciding to quit the Spanish club.
BeIN Sport, like PSG backed by Qatar, said in a tweet in Arabic on Monday that Neymar had decided to leave the Catalan club, citing a club management source at Barcelona.
However, following his latest social media postings, some Spanish media were reporting that Neymar is headed home to Barcelona and is expected to arrive on a flight from Dubai at 8.55pm (1855 GMT).
While Neymar has studiously remained silent about his future, Barca coach Ernesto Valverde is expecting him back at the club on Wednesday for the resumption of training, although Spanish sports media claim he won't turn up.
Neymar, though, has a nasty surprise awaiting him upon his return as Barcelona have blocked payment of a 26-million-euro ($31-million) bonus he is due, a source at the club said.
"These 26 million euros have been placed with a notary pending to see if the player continues," the source, who refused to be named, told AFP.
The renewal bonus was agreed on a year ago when Neymar extended his contract with Barcelona until 2021, and was due to be paid to the player after he completed a year.
But the club has decided to put it on hold while waiting to see how his transfer situation evolves.
The contract Neymar signed also increased an early termination clause from 200 to 222 million euros, which PSG are reportedly willing to pay.
Neymar first made his name at Santos, the former club of Brazil legend Pele, with whom he won the Copa Libertadores and Brazilian Cup.
A big-money move to Barca followed in 2013 as 56,000 fans turned up for his official unveiling at the Camp Nou.
In his four years with the Catalans he has won the Champions League in 2015, La Liga twice, the Spanish Cup three times and one FIFA Club World Cup.
Last year he also helped Brazil on home soil win the Olympic title for the first time.
