Possibly should add a enable/disable option as well?
Might make it easier to test this code without having
to install and uninstall the -dev package.
Also it's pointless if internal FFmpeg is disabled,
maybe have it forced to no in that case?

If adding a enable/disable option, this part
probably should go outside of the "auto" if.

Most importantly you would want to remove DASH from here (approx. line 1661):
libavdemuxers=$(filter_out_component demuxer 'AVISYNTH DASH LIB[A-Z0-9_]* REDIR VAPOURSYNTH')
and in the "else" case when libxml2 is disabled do a
libavdemuxers=$(filter_out_component demuxer 'DASH')
Otherwise the patch looks like the right approach, yes.
