Subject: Improve reference_invalid support
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5cbf8cf1ee08772a75278c5d9b5cd8d39874e3bb;p=libx264

Improve reference_invalid support
Reference invalidation can now be used to invalidate multiple frames at a time, rather than being limited to one per encoder_encode call.
