Looks like the H264 MAIN profile is not supported. Works better with BASELINE. Check if this is something we can do on aiortc side

FabienDanieau commented 11 months ago

aiortc seems limited to BASELINE profiles only. On going issue on their side https://github.com/aiortc/aiortc/issues/944 There is a workaround in my comment

FabienDanieau commented 3 months ago

aiortc removed from dependencie (see #40 )
