Subject: Fix x264_encoder_reconfig with multithreading
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6a5a20431f448aaa43036cdaa024c8017d63fa04;p=libx264

Fix x264_encoder_reconfig with multithreading
New behavior: reconfigging the encoder will result in changes being applied
to each of the encoding threads as they finish encoding the current frame.
