I didn't try to fix the Sphinx output in LaTeX format when a PNG image is used, but, from the above log, clearly it did something wrong. Perhaps there's something bad defined at the sphinx.sty file, or it simply generates the wrong LaTeX code when the image is not on PDF format. > [...] > > And it may even require "--shell-escape" to be passed at the xelatex > > call if inkscape is not in the path, with seems to be a strong > > indication that SVG support is not native to texlive, but, instead, > > just a way to make LaTeX to call inkscape to do the image conversion. > > Please don't require --shell-escape as part of the TeX workflow.

I sent a patch series to linux-doc, doing the conversion in advance: https://marc.info/?l=linux-doc&m=147859902804144&w=2 Not sure why, but the archives don't have all patches yet. Anyway, the relevant one is this: https://git.linuxtv.org/mchehab/experimental.git/commit/?h=pdf-fixes&id=5d41c452c787f6a6c755a3855312435bc439acb8 It basically calls ImageMagick "convert" tool for all png and pdf files currently at the documentation (they're all at media, ATM).
