MacOS 12.5.1

[Valkhes]

This has been reproduced on my side on a mac M1, macOS 12.6, after cloning the repo.

I'm using go version 1.19 darwin/arm64

Maybe do we need to specifically use go version 1.15 ?

EDIT : Seems to be crashing on the SetProperty("is-live",true)

I had to export the env variable GST_PLUGIN_PATH :

"export GST_PLUGIN_PATH=/opt/homebrew/lib/gstreamer-1.0"

It worked after

[HardlyAnyHoldings]

How did you get this working again?

I am still having issues even after doing

"export GST_PLUGIN_PATH=/usr/local/Cellar/gstreamer/1.20.5"

[danielpaulus]

hm weird it just worked on Ventura 13.1 with an USB-C iPAD Air iOS 16.1.1
Let me see if I can repro

[danielpaulus]

same for my iPhone 14, I get this annoying signal: illegal instruction now and then, so I have to start and kill the command like 5 times but eventually it always works. I will investigate if I can make the gstreamer part more stable.

[danielpaulus]

also I am using GStreamer 1.18.4
gst-launch-1.0 --version
is that maybe the issue?

[danielpaulus]

I just tried pushing the AV data through the local TCP loopback interface and just running gstreamer in a separate process from qvh and it seems to work perfectly fine. I will try and push a prototype branch tonight. I am fairly confident this will solve all of the gstreamer problems and allow easy use of ffmpeg as well.

@danielpaulus I am having an issue with running the code too. On the main branch, I run into the original issue posted here. I then switched to using the externalizeGST branch to launch a separate process for gstreamer. Unfortunately, my gst invoke url doesn't seem to be working. Would you mind sharing the gst command you used to get the process going?
