Bug: background ffmpeg state no longer present in 2.4.0 RC1

[sandercox]

Observed Behavior

Our software listens on OSC for the path of the video file that was queued up to play next on a channel/layer. This worked flawlessly before but testing the latest 2.4.0 RC1 builds it seems to have broken not too long ago.

FFmpeg (path) status of background objects is not sent

Expected behaviour

FFmpeg path status of background objects is sent

Steps to reproduce

1. start casparcg
2. send loadbg ch-lay file auto
3. notice that in the OSC data the background ffmpeg producer has no path / is not sent

Environment

I ran a git bisect to identify it was broken since this commit

I can confirm this issue.

v2.4.0-rc1 (12b4320) does have that issue.
v2.4.0-beta1 (6b339fc) is working as expected.

XML produced by AMCP command INFO 1 is also missing background data.

At least the following OSC addresses / XML elements are missing:

	*/background/file/clip
	*/background/file/name
	*/background/file/path
	*/background/file/time
	*/background/loop
	*/background/transition/frame
	*/background/transition/producer
	*/background/transition/type
