`video.add_text`(with long text) restarts cycle before the end of the text

[kessenza]

@smimram I am sorry to open this issue again. This fix b5b95cf doesn't solve the same issue reported here #2620 as described in the comment here https://github.com/savonet/liquidsoap/commit/b5b95cf2223f13ab61c878730e9ffc2c1111d7db#commitcomment-86059446

[smimram]

Let's continue the discussion here. I don't think that your theory about the dimensions of the text is true (that it returns the dimensions of the video frame). For instance, you can test this with

# A 1k char text
text = string.make(char_code=97, 1000)
# Generate image
t = video.text.native(text)
# Add dimensions
t = video.dimensions(video.crop(t))
# Print width after one second (on startup the text is not yet rendered and the width is reported as 0)
thread.run(delay=1.,{print("width: #{t.width()}")})
# Display the text
output.graphics(t)

This prints 14396 here, which is clearly above the frame dimensions. Do you get a similar result on your side? (It's not entirely impossible that some bug was corrected wrt video handling since last release...)

You should also be able to test by adding something like print("width: #{t.width()}") in the standard library.

If you have a minimal reproduction case along the above lines, I'd be glad to help!

[kessenza]

Well as you know I am not so strong in liquid. So I did a lot of tests before writing. So well yes in all my test print("width: #{t.width()}") this showed 1280 and not the length of the text. I'll put here a PoC and logs later. Thanks for the moment

[kessenza]

Here you are @smimram This is my code and I am attaching ls log. As you can see it always say short text width: 1280 long text width: 1280 Hope it helps Thanks test_ls.log

t_long = video.dimensions(video.crop(t_long))

log.info("short text width: #{t_short.width()} long text width: #{t_long.width()} ") #print before adding to source (I noticed somethimes some values change a bit)

[smimram]

It looks like a bug which has been fixed (I have been updating much video handling lately). I get here

2022/10/10 17:53:19 [lang:4] short text width: 122 long text width: 122 
2022/10/10 17:53:19 [lang:4] short text width: 1403 long text width: 1403 

By any chance, could you try the latest git? (or wait for the next release :()

[kessenza]

I thought to be already on the latest git. Am I not? My opam is pinned to liquidsoap.2.1.2 http https://github.com/savonet/liquidsoap/archive/refs/tags/rolling-release-v2.1.x.zip and log reports this version

I did now opam update and then opam upgrade but the issue still exists.

What should I do to pin liquidsoap to the latest git, different from what already I did? Thanks

[smimram]

Nope, here I have:

You should do opam pin add . on a checkout of the git in main branch.

[kessenza]

I did

git clone https://github.com/savonet/liquidsoap.git
cd liquidsoap
opam pin add liquidsoap .

But I have

Sorry, no solution found: there seems to be a problem with your request.

[NOTE] Pinning command successful, but your installed packages may be out of sync.

And no Liquidsoap package is installed. Even if I do

[toots]

The command should be:

opam pin add .

Notice that the liquidsoap part is gone, this is because there are more than one package to pin now.

[kessenza]

This works better but still problem (sorry to bug you again).

When you have time, it would be nice to have further info to know how to setup liquidsoap locally based on main git checkout. My tries failed as stated above Thanks

[smimram]

What is the output of opam pin list? I'd say that you have to also pin mm and ffmpeg to the latest versions.

I'd say that you have to also pin mm and ffmpeg to the latest versions --> how can I do it?

[smimram]

You should clone

• https://github.com/savonet/ocaml-mm
• https://github.com/savonet/ocaml-ffmpeg

and opam pin add . in the resulting repositories

[smimram]

By any chance, does opam update improve the situation?

[smimram]

Also what is your current version of ocaml (you can run opam switch to know it)?

[kessenza]

opam switch
[WARNING] Running as root is not recommended
#  switch   compiler                    description
   4.10.0   ocaml-base-compiler.4.10.0  4.10.0
   default  ocaml-system.4.08.1         default
→  ocaml    ocaml-base-compiler.4.14.0  ocaml

opam update -> nothing opam upgrade --> error --> --with-fixup --> nothing opam install liquidsoap (after update and upgrade and/or fixup) --> nothing

sorry. If you have any other ideas I can try otherwise I can wait for next package official release. In the meantime I worked around my script to avoid to use text. width.

So not so urgent if you are busy

[smimram]

Ok that's it! You need to install a more recent version of liquidsoap:

opam switch create 4.14.0

[kessenza]

Not sure as you can see my current switch was already based on 4.14.0 → ocaml ocaml-base-compiler.4.14.0 ocaml

Anyway I tried to opam switch create 4.14.0 and the pin again to mm and ffmpeg and liquidsoap

but no way I always got "Sorry, no solution found: there seems to be a problem with your request." and update/upgrade actions do not solve either
