In other words, no additional version limiting conditions seem to be required. Additionally, add a FATE test which verifies that pass-through of the MDCV/CLL side data is working during encoding. --- libavcodec/libsvtav1.c | 69 ++++++++++++++++++++++++++++++++++ tests/fate/enc_external.mak | 5 +++ tests/ref/fate/libsvtav1-hdr10 | 14 +++++++ 3 files changed, 88 insertions(+) create mode 100644 tests/ref/fate/libsvtav1-hdr10 diff --git a/libavcodec/libsvtav1.c b/libavcodec/libsvtav1.c index 7721e01677..6400a6507a 100644 --- a/libavcodec/libsvtav1.c +++ b/libavcodec/libsvtav1.c @@ -27,6 +27,8 @@ #include "libavutil/common.h" #include "libavutil/frame.h" #include "libavutil/imgutils.h" +#include "libavutil/intreadwrite.h" +#include "libavutil/mastering_display_metadata.h" #include "libavutil/opt.h" #include "libavutil/pixdesc.h" #include "libavutil/avassert.h" @@ -136,6 +138,71 @@ static int alloc_buffer(EbSvtAv1EncConfiguration *config, SvtContext *svt_enc) } +static void handle_mdcv(struct EbSvtAv1MasteringDisplayInfo *dst, + const AVMasteringDisplayMetadata *mdcv) +{ + if (mdcv->has_primaries) { + const struct EbSvtAv1ChromaPoints *const points[] = { + &dst->r, + &dst->g, + &dst->b, + }; + + for (int i = 0; i < 3; i++) { + const struct EbSvtAv1ChromaPoints *dst = points[i]; + const AVRational *src = mdcv->display_primaries[i]; + + AV_WB16(&dst->x, + av_rescale_q(1, src[0], (AVRational){ 1, (1 << 16) })); + AV_WB16(&dst->y, + av_rescale_q(1, src[1], (AVRational){ 1, (1 << 16) })); + } + + AV_WB16(&dst->white_point.x, + av_rescale_q(1, mdcv->white_point[0], + (AVRational){ 1, (1 << 16) })); + AV_WB16(&dst->white_point.y, + av_rescale_q(1, mdcv->white_point[1], + (AVRational){ 1, (1 << 16) })); + } + + if (mdcv->has_luminance) { + AV_WB32(&dst->max_luma, + av_rescale_q(1, mdcv->max_luminance, + (AVRational){ 1, (1 << 8) })); + AV_WB32(&dst->min_luma, + av_rescale_q(1, mdcv->min_luminance, + (AVRational){ 1, (1 << 14) })); + } +} + +static void handle_side_data(AVCodecContext *avctx, + EbSvtAv1EncConfiguration *param) +{ + const AVFrameSideData *cll_sd = + av_frame_side_data_get( + (const AVFrameSideData **)avctx->decoded_side_data, + avctx->nb_decoded_side_data, AV_FRAME_DATA_CONTENT_LIGHT_LEVEL); + const AVFrameSideData *mdcv_sd = + av_frame_side_data_get( + (const AVFrameSideData **)avctx->decoded_side_data, + avctx->nb_decoded_side_data, + AV_FRAME_DATA_MASTERING_DISPLAY_METADATA); + + if (cll_sd) { + const AVContentLightMetadata *cll = + (AVContentLightMetadata *)cll_sd->data; + + AV_WB16(¶m->content_light_level.max_cll, cll->MaxCLL); + AV_WB16(¶m->content_light_level.max_fall, cll->MaxFALL); + } + + if (mdcv_sd) { + handle_mdcv(¶m->mastering_display, + (AVMasteringDisplayMetadata *)mdcv_sd->data); + } +} + static int config_enc_params(EbSvtAv1EncConfiguration *param, AVCodecContext *avctx) { @@ -254,6 +321,8 @@ FF_ENABLE_DEPRECATION_WARNINGS /* 2 = IDR, closed GOP, 1 = CRA, open GOP */ param->intra_refresh_type = avctx->flags & AV_CODEC_FLAG_CLOSED_GOP ?
