Cosby is charged with drugging and sexually assaulting former Temple University employee Andrea Constand at his home in 2004.
There was no message included with the video, which was soundtracked with the Harlem Globetrotters theme, and no explanation for why there was a basketball hoop in the courthouse.
On Thursday, the 12-person jury announced that it was unable to reach a unanimous decision after nearly 30 hours of deliberation but were sent back to the negotiating table by the judge.
Reporters rushed outside to file the news and I think it's the first time I've had an elderly lady try and shoulder barge me as she rushed to be first to tweet.
Legal experts said the trial fits the "he said, she said" arguments so common to sexual offense cases. "We definitely want this thing to end, and hope the judge will tell jurors they've done their civic duty and that they've done it with ethics and integrity, and release them".
Cosby faces up to 10 years in prison if convicted on all three felony counts.
The AP does not typically identify people who say they are victims of sexual assault unless they grant permission, which Constand has done.
Cosby is accused of drugging and molesting Andrea Constand in 2004.
Regardless of the court's decision Mr. Cosby's days inside a courtroom will not be over any time soon.
It remains the sole discretion of the judge in charge of the trial to send back the jury as many times as required to continue deliberations and to decide when to declare a hung jury and mistrial. Cosby declined to testify in his own defense, and his attorneys only called one witness.
In it, he claimed Constand showed no ill effects from the 1½ Benadryl pills he gave her to help her relax and that she never objected to his behavior during the encounter.
Cosby did not testify.
They've deliberated almost 40 hours since getting the case.
Cosby's defense team argued that Constand and prosecutors are misrepresenting what occurred that day and that the sexual activity was consensual, which Constand and prosecutors reject.
The jurors have spent days wrestling with which version of the night in question was accurate: Constand's or Cosby's.
Prosecutors, meanwhile, used Constand's testimony as well as the words of a second accuser, Kelly Johnson, to portray Cosby as a serial predator.
The jurors then asked to hear Constand's testimony again Wednesday; indicating that some members of the jury are trying to show the other jurors how inconsistent Constand's statements have been, bringing reasonable doubt.
"They're conflicted about the inconsistencies in Ms. Constand's testimony", spokesman Andrew Wyatt said.
