What is the most common cause of live stream failure?

Audio, by a distance. Not a dramatic failure but a microphone not switched on, a feed taken from the wrong output, a level set during a soundcheck that is wrong once the room is full, or a laptop playing a video with no audio path to the stream. Viewers leave a stream they cannot hear far faster than one that looks poor.

How often does equipment actually fail mid-show?

Rarely. It is the failure people worry about most and the least common in practice. Cameras and mixers seldom die mid-show, which is why quotes include spare kit that hopefully sits unused all day.

What Actually Goes Wrong on a Live Stream

Q: Does redundancy mean nothing can go wrong?

No. Redundancy covers a single point of failure gracefully. It does not cover a plan that was wrong to begin with, a venue that changed the room, or a running order rewritten at ten in the morning.

Every supplier says their streams do not fail. Here is what genuinely goes wrong, roughly in order of how often we see it.

Audio, most of the time

Not a dramatic failure. A microphone not switched on, a feed taken from the wrong output, a level set during a soundcheck that is wrong once the room is full, a laptop playing a video with no audio path to the stream.

Audio is the most common problem and the most damaging, because viewers leave a stream they cannot hear far faster than one that looks poor.

The fix is checking every source before doors, and having somebody listening to the output for the whole show.

Connectivity

Less common than people expect if it has been planned, very common if it has not. A venue's guest WiFi going down as the room fills is the classic version.

Bonded connections across multiple carriers plus satellite make this a non-event. The question is whether failover is automatic or whether somebody has to notice first.

Presentation and playback

A presenter arrives with a file that will not play, a video with an unsupported codec, a laptop that will not output at the right resolution, a lock screen appearing mid-session.

This is the second most common failure and it is almost entirely preventable by collecting files in advance and testing them.

Power

Rare on a properly planned job. When it happens it is usually a shared circuit somebody else has overloaded, not a generator failure.

Human error

Cutting to the wrong source, a graphic left up, a microphone left open during a break. Happens to everyone. Rehearsal reduces it.

Actual equipment failure

The one people worry about most and the least common. Cameras and mixers rarely die mid-show. When they do, the answer is a spare, which is why quotes include kit that hopefully sits unused.

What redundancy does and does not cover

It covers a single point of failure gracefully. It does not cover a plan that was wrong to begin with, a venue that changed the room, or a running order rewritten at ten in the morning.
