Andreas Rheinhardt 879eed5555 avcodec/ttmlenc: Deduplicate ttml_default_namespacing string
String literals are allowed to be deduplicated (and toolchains
are already capable of doing so), yet the same is not allowed
for named arrays (even when they contain strings). Therefore
use a const char *const pointing to an unnamed string literal
for ttml_default_namespacing.
