The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report! Could you please paste the contents of your about:support page? If you try Firefox safe mode, do you still run into the same issue? If this is new behavior that just started and is due to a change in Firefox itself, we may be able to track it down more precisely with mozregression - it'll have you test a bunch of different builds and give us the exact changes which may be causing the problem.

The "progress" marker shows [0, 17.766s) buffered, and "canplaythrough" has fired.
A profile with more information can be obtained by following the steps in Bug 1935757 comment 2.

Redirect a needinfo that is pending on an inactive user to the triage owner.
:jimm, since the bug has recent activity, could you have a look please?

The behavior under different values of the following prefs would indicate whether bug 1938056 might be causing this:
media.hardware-video-decoding.enabled
