avcodec/libx265: improve full range flag setting logic Unlike libx264, libx265 does not have a separate "unspecified"/"auto" default for color range, so we do always have to specify it. Thus, we are required to handle the RGB case on the libavcodec side to enable the correct value to be written out in in case of RGB content with unspecified color range being received. In other words: 1. If the user has set color range specifically, follow that. 2. If the user has not set color range specifically, set full range by default in case of RGB and YUVJ pixel formats. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=dbe40478e293f78c5a5e4302eb3f38257106ee86 --- libavcodec/libx265.c | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/libavcodec/libx265.c b/libavcodec/libx265.c index 9395120471..b5c94b64a3 100644 --- a/libavcodec/libx265.c +++ b/libavcodec/libx265.c @@ -181,10 +181,15 @@ static av_cold int libx265_encode_init(AVCodecContext *avctx) ctx->params->vui.bEnableVideoSignalTypePresentFlag = 1; - ctx->params->vui.bEnableVideoFullRangeFlag = avctx->pix_fmt == AV_PIX_FMT_YUVJ420P || - avctx->pix_fmt == AV_PIX_FMT_YUVJ422P || - avctx->pix_fmt == AV_PIX_FMT_YUVJ444P || - avctx->color_range == AVCOL_RANGE_JPEG; + if (avctx->color_range != AVCOL_RANGE_UNSPECIFIED) + ctx->params->vui.bEnableVideoFullRangeFlag = + avctx->color_range == AVCOL_RANGE_JPEG; + else + ctx->params->vui.bEnableVideoFullRangeFlag = + (av_pix_fmt_desc_get(avctx->pix_fmt)->flags & AV_PIX_FMT_FLAG_RGB) || + avctx->pix_fmt == AV_PIX_FMT_YUVJ420P || + avctx->pix_fmt == AV_PIX_FMT_YUVJ422P || + avctx->pix_fmt == AV_PIX_FMT_YUVJ444P; if ((avctx->color_primaries <= AVCOL_PRI_SMPTE432 && avctx->color_primaries != AVCOL_PRI_UNSPECIFIED) || _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
