Re: [video repo] when making videos inside container images break

Hi!

> I tried adding it to the container, and it seems to be working fine here.
I've been working on the wrong file (the environment.sh) and could not
get why it still didn't work. Fixed the script and now will be pushing
the remaining videos.
Thanks for the explanation :)

Regards

Yes, the container misses cairo. Could you try adding at, and see if
the problem persists?

How did I found it? (for myself and for future reference)

I identified that the problem is that the container misses something.
All work fine, if you don't specify the -C option.

Then the hard thing was to find out, what that something was.

I straced the thing in the container, and also did that with the working one,
outside the container.

The svg file was opened quite at the end, and I looked at the trace
from that point on.
It turned out that the image is tried to be opened as xpm... not as
png, as it should be.

Then I looked at the inkscape source, for quite a while...
The good thing to search for turned out to be Inkscape::Pixbuf, which
lead me to find that
inkscape uses cairo in concert with pixbuf.

Then I looked around the package definition of inkscape, where I found
no sign of cairo...

I tried adding it to the container, and it seems to be working fine here.

Sorry, so if you make the video "the hard way" -video by video and
gluing-, the issue disappears? it has to do with the cointainer then?

You can go ahead with that. I am busy here tracing down this bug.
I got strace for both of inside and outside the container, and it seems
that in the container the wrong pixbuf loader is picked up, namely xmp
instead of png.

Sorry, I realized that the second part of the packaging video has the
same issue.
May I upload the pictures in a separate directory inside the videos
facing this issue, so that people can have them if they want to, and
it to the README (ie: 03-help and 04-packaging2 are facing issues with
embedded images, they are stored temporarily in an image subdir until
the bug is solved).
WDTY?

I don't know about berlin, but hydra.gnu.org has *never* successfully
built ungoogled-chromium.  So far, it has made 3 attempts on
x86_64-linux and 5 attempts on i686-linux:

  https://hydra.gnu.org/build/3387889 (x86_64-linux)
  https://hydra.gnu.org/build/3381436 (x86_64-linux)
  https://hydra.gnu.org/build/3380876 (x86_64-linux)
  https://hydra.gnu.org/build/3386821 (i686-linux)
  https://hydra.gnu.org/build/3385227 (i686-linux)
  https://hydra.gnu.org/build/3381453 (i686-linux)
  https://hydra.gnu.org/build/3380895 (i686-linux)
  https://hydra.gnu.org/build/3379818 (i686-linux)

If the same is true on berlin.guixsd.org, that would explain the lack of
binary substitutes.
