The package again failed to build from source on ppc64 because of this bug:
https://buildd.debian.org/status/fetch.php?pkg=ffmpeg&arch=ppc64&ver=7%3A7.1.1-1%2Bb8&stamp=1756717384&raw=0
And I will have built it manually again. Can you please disable the ASM stuff
for ppc64 for the time being? It's better to have a slow ffmpeg package than
one that doesn't build at all.
Thanks,
Adrian
