same issue with me
I have a similar issue (although all the formats seem broken for me)
Recently upgraded my ffmpeg version. Looks like newer versions of ffmpeg -formats have added a new info column for devices, which adds a space between the mux/demux columns and the format name:
New (build from March 2024):
Formats:
D.. = Demuxing supported
.E. = Muxing supported
..d = Is a device
---
E mp4 MP4 (MPEG-4 Part 14)
Old (build from June 2023):
File formats:
D. = Demuxing supported
.E = Muxing supported
--
E mp4 MP4 (MPEG-4 Part 14)
(Obviously, mp4 is just an example, I'm not going to paste the whole format list here.)
My guess at what is happening:
The regex that Fluent-FFmpeg uses to read FFmpeg's format list and determine its format support doesn't know how to read the extra space, so Fluent thinks there aren't any valid formats.
Regex is here:
node-fluent-ffmpeg/lib/capabilities.js
Line 18 in 4e02d12
Then, when you try to run a command, the error checking at line 589 compares its (empty) list of valid formats to your format, determines it can't support the format, and throws the error.
@benharp I try running ffmpeg -format and I also had the same column for devices. Does this mean I have to downgrade my ffmpeg version? What version works for you?
Formats:
D.. = Demuxing supported
.E. = Muxing supported
..d = Is a device

@benharp followed your comment and downgraded my ffmpeg to ffmpeg version 6.1-full now it can finish the stream. Thanks your hint helps a lot!
@alpacaPwaa should this issue be closed? I mean, you can fix it by downgrading the version, but now Homebrew installs version 7 by default so maybe this should be taken into account now.
We should fix the regexpr and make a new fluent-ffmpeg version? Is that possible?
Any maintainer?
It seems like I have to re-open the issue, everyone here's right although there's a workaround for this issue it's still better to address the root cause.
Use patch-package until it gets fixed. This worked in my case:

Fixed here #1266
You can also install package from: https://www.npmjs.com/package/fluent-ffmpeg-7 and just change the import to from 'fluent-ffmpeg-7'
I did a quick version there till official version gets fixed.
Is there a way to skip format checks? I want my code to work on both version of ffmpeg
You can use my code, it works on both versions!
You can directly install from the npm with npm i fluent-ffmpeg-7. I called like that just to reinforce that it also works on FFmpeg 7
