Wanted change

Hi, is it possible to add libxml2 to tvheadend image?
Maybe ffmpeg needs the --enable-libxml2 option

Reason for change

it could be nice to make tvheadend manage .mpd link url via ffmpeg piping

We already install libxml2 but we don't compile ffmpeg from source so we don't have any control over the flags it uses.

thanks for quick reply
Other question:
is it possibile to try compile ffmpeg with --enable-libxml2 ? Or is there a way to use an external ffmpeg with --enable-libxml2 flag?

You'd have to find a version built against muslc for it to work on Alpine. You could also raise an issue against the Alpine package repos and request they add it, then we'd pull it in automatically - https://gitlab.alpinelinux.org/alpine/aports/-/issues

Thanks, I'll add TVH to our list for higher priority 3.18 rebases so it can take advantage of the new ffmpeg build. Might be several weeks though.
