video-stream not working on macOS 26 Tahoe

[KishanDasani]

I recently updated my macbook air M4 to macOS 26 Tahoe and since then idb stream is broken.

When I connect my iPhone 7 running on v15.8.3 and hit idb video-stream --udid <device ID> it gives below output.

"idb video-stream --udid
Running stream until ^C

the same command was working fine till I had macOS 15.7.

Current system details:
MacOS: 26
Xcode: 16.4
pyenv: 2.6.3
which idb: /Users/admin/.pyenv/shims/idb

I had the same issue, seems that you need to add "--fps 30" to get any frames out. Though my frames look corrupt, like a cyberpunk movie. mobilecli is using an agent on the device (that it automatically installs) and provides better results.
