* avutil/random_seed: use bcrypt instead of the old wincrypt APISteve Lhomme2018-04-141-9/+10
| | | | | | | | Remove the wincrypt API calls since we don't support XP anymore and bcrypt is available since Vista, even on Windows Store builds. Reviewed-by: Michael Niedermayer <[email protected]> Signed-off-by: James Almer <[email protected]>

* | lavu/random_seed: use arc4random() when availableGanesh Ajjanagadde2015-12-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | arc4random() was designed as a superior interface for system random number generation, designed for OpenBSD and subsequently incorporated by other BSD's, Mac OS X, and some non-standard libc's. It is thus an improvement to use it whenever available. As a side note, this may or may not get included in glibc, and there is a proposal to create a posix_random family based on these ideas: http://austingroupbugs.net/view.php?id=859. Tested on Mac OS X. Signed-off-by: Ganesh Ajjanagadde <[email protected]>

| * random_seed: Rewrite the generic clock() based seed codeMichael Niedermayer2014-01-061-21/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new code is faster and reuses the previous state in case of multiple calls. The previous code could easily end up in near-infinite loops, if the difference between two clock() calls never was larger than 1. This makes fate-parseutils finish in finite time when run in wine, if CryptGenRandom isn't available (which e.g. isn't available if targeting Windows RT/metro). Patch originally by Michael Niedermayer but with some modifications by Martin Storsjö. Signed-off-by: Martin Storsjö <[email protected]>

* random_seed: allow to block on /dev/randomMåns Rullgård2010-07-011-3/+0
| | | | | | | | | | If both /dev/random and /dev/urandom failed to return data, an uninitialised value might be returned. Since most systems have a non-blocking /dev/urandom or have /dev/random with similar properties, the chance of blocking is minimal, and the alternative of returning non-random data is worse.
