Disable use of stream IDs if there are duplicates, rather than rewriting.

2025-10-15T20:33:26Z

It turns out that FFmpeg decoders (e.g. flv, see FFmpeg 25faaa311a74efdfdc4fed56996d7338ed807488) check stream IDs and sometimes create new streams if they see one that they didn't see before. If we change stream IDs we break this. Here we try to use stream indices in cases where the IDs are duplicated. We also account for the case where a new stream appears during examination. This wasn't covered by tests until the FFmpeg commit mentioned above, were the flv decoder creates a new stream during examination of boon_telly.mkv.

Cleanup: use fmt::to_string().

Bump libdcp for raw_convert changes.

raw_convert is gone, so here we use fmt::{to_string,format} instead. Other raw_converts now use fast_float.

Remove all use of add_child() from xmlpp.
