BIO_get_new_index() is static counter meant to get index for custom bio type definition. As we can read in the documentation: > Note that BIO_get_new_index() can only be used 127 times before it > returns an error. We cannot call it repeatedly, because it will fail eventually. To my understanding the index is not needed in our use and we could safely use BIO_TYPE_NONE. Documentation states: > type can be set to either BIO_TYPE_NONE or via BIO_get_new_index() if > a unique type is required for searching (See BIO_find_type(3)) We don't use any search related functions. This reverts commit 816dad231f5b312fd98e81cc6a6cbaf47c1e26a5. Fixes: https://github.com/mpv-player/mpv/issues/16589
