Yeah, it would break both versions 1 and 2, assuming anything tries to
parse the hex value for some purpose, as both are expected to have it.
And for that matter it would also break parsing framecrc in a similar
This can be solved with a new version 3. But that only covers the
muxers framehash and framemd5, and not framecrc as used by most fate
tests, which also calls ff_framehash_write_header(), the function that
prints this line.
What would be the best course of action here?
