You may assume that I already did that.
IMHO, the main issue is not drawtext, but where to get the text from.
There only a few ready-made options, all other information has to be
drawn from metadata provided by some other source.

After some more digging, it seems that I need to set some options while
decoding a mov file - at least from reading
https://ffmpeg.org/doxygen/trunk/mov_8c_source.html
How would I go about doing this? I'm happy to build a new application based
on libavformat, but I'm not sure how to interface with
our admin guys said that they aren't blocked any domain, so it is strange.

I'm trying to capture the raw signal from a Blackmagic Micro Studio 4K

Yes, we tested our application for several months with a built-in VLC player
and it worked well.
VLC needs several attempts to start playing the stream but then it works fine.

I'm hoping to use ffmpeg as a generic, cross-platform, tool to read

From what I cant tell, ffmpeg easily supports this for mp3 files. For

Do you know if it is restricted to a Domain or a list of IP's?
I am asking it because from my house I can, but from my work, I can't. It
sounds like the IP/Domain from my work the repo is blocked, it is possible?
