From: Nicolas Dufresne Date: Wed, 16 Mar 2022 17:17:21 +0000 (-0400) Subject: codecs: av1: Fix state when we show existing keyframe X-Git-Tag: 1.22.0~2089 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=049655c82455a0c24bf95fba8f700dd4758cc656;p=platform%2Fupstream%2Fgstreamer.git codecs: av1: Fix state when we show existing keyframe Showing existing keyframe have special meaning in AV1. All the references frame will be refreshed with the original keyframe information. The refresh process (7.20) is implemented by saving data from the frame_header into the state. To fix this special case, load all the relevant information into the frame_header. As there is nothing happening in between this and the loading of the key-frame into the state, this patch also remove the separate API function, using it internally instead. Fixes #1090 Part-of: --- diff --git a/subprojects/gst-docs/symbols/symbol_index.json b/subprojects/gst-docs/symbols/symbol_index.json index 02270e3..7741aae 100644 --- a/subprojects/gst-docs/symbols/symbol_index.json +++ b/subprojects/gst-docs/symbols/symbol_index.json @@ -37478,7 +37478,6 @@ "gst_av1_parser_parse_temporal_delimiter_obu", "gst_av1_parser_parse_tile_group_obu", "gst_av1_parser_parse_tile_list_obu", - "gst_av1_parser_reference_frame_loading", "gst_av1_parser_reference_frame_update", "gst_av1_parser_reset", "gst_av1_parser_reset_annex_b", @@ -66199,4 +66198,4 @@ "zbar:message", "zebrastripe", "zebrastripe:threshold" -] \ No newline at end of file +] diff --git a/subprojects/gst-plugins-bad/gst-libs/gst/codecparsers/gstav1parser.c b/subprojects/gst-plugins-bad/gst-libs/gst/codecparsers/gstav1parser.c index 5fa283c..fb1050f 100644 --- a/subprojects/gst-plugins-bad/gst-libs/gst/codecparsers/gstav1parser.c +++ b/subprojects/gst-plugins-bad/gst-libs/gst/codecparsers/gstav1parser.c @@ -67,10 +67,6 @@ * should call gst_av1_parser_reference_frame_update() to update the parser's inside * state(such as reference information, global segmentation information, etc). * - * Note: If the frame is actived by show_existing_frame in #GST_AV1_OBU_FRAME_HEADER, - * the function of gst_av1_parser_reference_frame_loading() should be called before - * really showing that frame. - * * @since: 1.18.00 */ @@ -3496,6 +3492,64 @@ gst_av1_set_frame_refs (GstAV1Parser * parser, frame_header->ref_frame_idx[i] = ref;
