Raspivid hangs

Hello

When starting raspivid it hangs, no printouts or log entries.

I found out its hanging on: vc_vchi_tv_init()
When commented out the app works OK.

Perhaps @ogra has some idea what’s not working here?

i’ll try to take a look this week but note that i’m at a sprint and my days are curremtly very full …
