From 75c7e4583f4fd727d236a12763a265502fe00988 Mon Sep 17 00:00:00 2001 From: Carl Eugen Hoyos Date: Sat, 16 Mar 2013 20:13:44 +0100 Subject: [PATCH] Do not (re-)set libx264 parameter b_tff if interlaced encoding was not requested. Reconfiguring can break x264 lossless encoding. Fixes ticket #2165. --- libavcodec/libx264.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libavcodec/libx264.c b/libavcodec/libx264.c index a394213680..7e8fa65818 100644 --- a/libavcodec/libx264.c +++ b/libavcodec/libx264.c @@ -175,7 +175,7 @@ static int X264_frame(AVCodecContext *ctx, AVPacket *pkt, const AVFrame *frame, frame->pict_type == AV_PICTURE_TYPE_P ?
