libavcodec/libx265: add user data unregistered SEI encoding MISB ST 0604 and ST 2101 require user data unregistered SEI messages (precision timestamps and sensor identifiers) to be included. That currently isn't supported for libx265. This patch adds support for user data unregistered SEI messages in accordance with ISO/IEC 23008-2:2020 Section D.2.7 The design is based on nvenc, with support finished up at 57de80673cb Signed-off-by: Derek Buitenhuis <[email protected]> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=1f58503013720700a5adfd72c708e6275aefc165 --- libavcodec/libx265.c | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) diff --git a/libavcodec/libx265.c b/libavcodec/libx265.c index 90658d3d9e..9395120471 100644 --- a/libavcodec/libx265.c +++ b/libavcodec/libx265.c @@ -35,6 +35,7 @@ #include "encode.h" #include "internal.h" #include "packet_internal.h" +#include "sei.h" typedef struct libx265Context { const AVClass *class; @@ -51,6 +52,9 @@ typedef struct libx265Context { char *profile; AVDictionary *x265_opts; + void *sei_data; + int sei_data_size; + /** * If the encoder does not support ROI then warn the first time we * encounter a frame with ROI side data. @@ -78,6 +82,7 @@ static av_cold int libx265_encode_close(AVCodecContext *avctx) libx265Context *ctx = avctx->priv_data; ctx->api->param_free(ctx->params); + av_freep(&ctx->sei_data); if (ctx->encoder) ctx->api->encoder_close(ctx->encoder); @@ -489,6 +494,8 @@ static int libx265_encode_frame(AVCodecContext *avctx, AVPacket *pkt, ctx->api->picture_init(ctx->params, &x265pic); if (pic) { + x265_sei *sei = &x265pic.userSEI; + sei->numPayloads = 0; for (i = 0; i < 3; i++) { x265pic.planes[i] = pic->data[i]; x265pic.stride[i] = pic->linesize[i]; @@ -516,6 +523,32 @@ static int libx265_encode_frame(AVCodecContext *avctx, AVPacket *pkt, memcpy(x265pic.userData, &pic->reordered_opaque, sizeof(pic->reordered_opaque)); } + + for (i = 0; i < pic->nb_side_data; i++) { + AVFrameSideData *side_data = pic->side_data[i]; + void *tmp; + x265_sei_payload *sei_payload; + + if (side_data->type != AV_FRAME_DATA_SEI_UNREGISTERED) + continue; + + tmp = av_fast_realloc(ctx->sei_data, + &ctx->sei_data_size, + (sei->numPayloads + 1) * sizeof(*sei_payload)); + if (!tmp) { + av_freep(&x265pic.userData); + av_freep(&x265pic.quantOffsets); + return AVERROR(ENOMEM); + } + ctx->sei_data = tmp; + sei->payloads = ctx->sei_data; + sei_payload = &sei->payloads[sei->numPayloads]; + sei_payload->payload = side_data->data; + sei_payload->payloadSize = side_data->size; + /* Equal to libx265 USER_DATA_UNREGISTERED */ + sei_payload->payloadType = SEI_TYPE_USER_DATA_UNREGISTERED; + sei->numPayloads++; + } } ret = ctx->api->encoder_encode(ctx->encoder, &nal, &nnal, _______________________________________________ ffmpeg-cvslog mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
