[Savonet-users] [savonet/liquidsoap] "Failed to prepare track: request not ready" when using annotate. (#636)
I'm trying to create a video with a slideshow (sort of). i'm tried to imitate
the slideshow script from
[here](https://www.liquidsoap.info/doc-dev/on2_part3.html).
```
audio = playlist("some/folder/") # .mp3 files
video = playlist.safe(prefix="annotate:duration=3:", "images.txt") # .jpeg/.jpg
files
source = mux_video(video=video, audio)
output.youtube.live(key="hackme", fallible=true, source)
```
i stripped away some fancypants stuff for better readability - if noone can
reproduce this, i 'll put it here, too.
whenever i try to use `prefix=`, the output is spammed with
```
[images(dot)txt:1] Failed to prepare track: request not ready.
```
i checked my syntax at least a dozen times. when i remove ´prefix`, everything
is back to normal.
i'm running the almost latest master (b44f282c4d8bc2e5cb6a514b226aa352e4db9bb4).
