From 7369595c556516b90bf3acdf85043dc11add7d89 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jan=20Ekstr=C3=B6m?= Date: Fri, 11 Sep 2020 00:36:23 +0300 Subject: [PATCH] ffmpeg: pass decoded or filtered AVFrame to output stream initialization Additionally, reap the first rewards by being able to set the color related encoding values based on the passed AVFrame. The only tests that seem to have changed their results with this change seem to be the MXF tests. There, the muxer writes the limited/full range flag to the output container if the encoder is not set to "unspecified". --- fftools/ffmpeg.c | 33 ++++++++++++++++++++++----------- tests/ref/lavf/mxf_d10 | 2 +- tests/ref/lavf/mxf_dv25 | 2 +- tests/ref/lavf/mxf_dvcpro50 | 2 +- tests/ref/lavf/mxf_opatom | 2 +- 5 files changed, 26 insertions(+), 15 deletions(-) diff --git a/fftools/ffmpeg.c b/fftools/ffmpeg.c index 52d1b09c78..20d191bcf6 100644 --- a/fftools/ffmpeg.c +++ b/fftools/ffmpeg.c @@ -947,9 +947,11 @@ early_exit: return float_pts;
