Julian Assange sees himself in newly published material skateboarding in the Ecuadorian Embassy, which illustrates his deteriorating relationship with the staff of the building.
The WikiLeaks founder was in the London Embassy for more than seven years before being arrested on Thursday.
Security footage, obtained from the Spanish newspaper El Pais, showed Assange in his living quarters and captured a furious quarrel between the Australian and a security guard.
One sees the 47-year-old Assange dressed in a vest and shorts while trying to ride a skateboard.
Assange is also seen to have collided with a guard while holding a meeting with visitors who are reportedly refusing to leave.
The footage shows him pointing a camera at the guard who then tries to pull her away.
Assange's guests left after the ambassador arrived early in the morning.
It comes to Assange's lawyer accused Ecuador of asserting "outrageous" claims about his actions in their London embassy.
Jennifer Robinson told Sky News that allegations about her client's behavior – including the fact that he had smeared walls of feces – were used as an excuse to push him out.
Ecuador has alleged that Assange was reminded to flush the toilet, leave dirty underwear in the toilet, not clean the dishes and put on the stove.
Ms Robinson said: "Ecuador has made these allegations to justify the unlawful and extraordinary act of getting the police to a message.
"I have visited him for the last seven years, this man was in a room without outside access.
"It has become more difficult at the embassy, politics has changed as Ecuador's political situation has changed with a new leader."
Assange is imprisoned for up to 12 months after being convicted in 2012 of breaching his bail conditions upon joining the Ecuadorian embassy.
He took the step after losing his fight against extradition to Sweden, where he faced, among other things, rape.
Assange is now expected to fight extradition to the US for allegations he plotted with former army analyst Chelsea Manning to break into a secret government computer.
Labor leader Jeremy Corbyn joined Assange's supporters in saying that he should be protected from extradition to the US for his evidence of "atrocities" in Iraq and Afghanistan.
More than 70 MPs have also called on the government to ensure that Assange faces the Swedish authorities when they request its extradition.
