Gstreamer not working on M1 Max Macbook

[scalers-ai]

brew config output

1) MacBook Pro (14-inch, 2021) - Chip M1 Max
2) Installed gstreamer with this command: brew install gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-libav gst-rtsp-server gst-editing-services gst-devtools

3) Upon launching any gstreamer pipeline (already tried reinstalling, rebooting etc. etc.)
e.g.
gst-launch-1.0 videotestsrc ! fakesink

I get this error.

Verification

• [X] I ran brew update and am still able to reproduce my issue.
• [X] I have resolved all warnings from brew doctor and that did not fix my problem.

Where is the output of brew config?

What made you think Homebrew's code has an issue rather than the gstreamer project itself?

[scalers-ai]

1. The gstreamer standalone (non-Homebrew) does work
2. The gstreamer Homebrew build does not work

https://gstreamer.freedesktop.org/documentation/installing/on-mac-osx.html?gi-language=c

[SMillerDev]

Judging by the macOS versions referenced on that page that pkg is for a x86 version of gstreamer and it works only in Rosetta.

https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1358 indicates that gstreamer doesn't work on M1 macs

[scalers-ai]

Thanks for your prompt response!

The gstreamer build from the gstreamer site work. The "kind" shows up as "Apple" and not "Rosetta" indicating that it is in fact the M1 version.

Appreciate any pointers. Perhaps there may be some weird issue in an upstream dependency in the Homebrew builds (I don't know the internals)?

Below screenshots are from the "official" Gstreamer build. I would much prefer to use the Home-brew version, if possible, though.

The non-Homebrew version distributed by upstream (both runtime and development) seem to contain all fat libraries with both x86_64 and arm64 slices. I guess the GitLab issue linked above is outdated.

FYI, this looks M1-specific; works fine on my Intel machine:

When I tried commands on M1, after the GLib-GObject-WARNING/etc messages, the commands worked (below with fakesink and also tried autovideosink with no issue).

❯ gst-launch-1.0 videotestsrc ! fakesink

As far as I can tell, the logged warnings didn't impact particular functionality.

Anyway, it could be an upstream issue in gst-libav with FFmpeg 5 https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/1055
