From: Lynne <dev@lynne.ee> To: ffmpeg-devel@ffmpeg.org Cc: Lynne <dev@lynne.ee> Subject: [FFmpeg-devel] [PATCH v4 01/16] pixfmt: add AV_PIX_FMT_GBRAP32 Date: Thu, 13 Mar 2025 18:03:33 +0100 Message-ID: <20250313170355.92290-2-dev@lynne.ee> (raw) In-Reply-To: <20250313170355.92290-1-dev@lynne.ee> This commit adds a 32-bit *integer* planar RGBA format. Vulkan FFv1 decoding is best performed on separate planes, rather than packed RGBA (i.e. RGBA128), hence this is useful as an intermediate format. --- libavutil/pixdesc.c | 28 ++++++++++++++++++++++++++++ libavutil/pixfmt.h | 4 ++++ 2 files changed, 32 insertions(+) diff --git a/libavutil/pixdesc.c b/libavutil/pixdesc.c index 1917ae74d8..53adde5aba 100644 --- a/libavutil/pixdesc.c +++ b/libavutil/pixdesc.c @@ -1991,6 +1991,34 @@ static const AVPixFmtDescriptor av_pix_fmt_descriptors[AV_PIX_FMT_NB] = { .flags = AV_PIX_FMT_FLAG_BE | AV_PIX_FMT_FLAG_PLANAR | AV_PIX_FMT_FLAG_RGB | AV_PIX_FMT_FLAG_ALPHA, }, + [AV_PIX_FMT_GBRAP32LE] = { + .name = "gbrap32le", + .nb_components = 4, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 2, 4, 0, 0, 32 }, /* R */ + { 0, 4, 0, 0, 32 }, /* G */ + { 1, 4, 0, 0, 32 }, /* B */ + { 3, 4, 0, 0, 32 }, /* A */ + }, + .flags = AV_PIX_FMT_FLAG_PLANAR | AV_PIX_FMT_FLAG_RGB | + AV_PIX_FMT_FLAG_ALPHA, + }, + [AV_PIX_FMT_GBRAP32BE] = { + .name = "gbrap32be", + .nb_components = 4, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 2, 4, 0, 0, 32 }, /* R */ + { 0, 4, 0, 0, 32 }, /* G */ + { 1, 4, 0, 0, 32 }, /* B */ + { 3, 4, 0, 0, 32 }, /* A */ + }, + .flags = AV_PIX_FMT_FLAG_BE | AV_PIX_FMT_FLAG_PLANAR | + AV_PIX_FMT_FLAG_RGB | AV_PIX_FMT_FLAG_ALPHA, + }, [AV_PIX_FMT_VDPAU] = { .name = "vdpau", .log2_chroma_w = 1, diff --git a/libavutil/pixfmt.h b/libavutil/pixfmt.h index e6d2b08c5c..bf1b8ed008 100644 --- a/libavutil/pixfmt.h +++ b/libavutil/pixfmt.h @@ -485,6 +485,9 @@ enum AVPixelFormat { AV_PIX_FMT_YAF16BE, ///< IEEE-754 half precision packed YA, 16 bits gray, 16 bits alpha, 32bpp, big-endian AV_PIX_FMT_YAF16LE, ///< IEEE-754 half precision packed YA, 16 bits gray, 16 bits alpha, 32bpp, little-endian + AV_PIX_FMT_GBRAP32BE, ///< planar GBRA 4:4:4:4 128bpp, big-endian + AV_PIX_FMT_GBRAP32LE, ///< planar GBRA 4:4:4:4 128bpp, little-endian + AV_PIX_FMT_NB ///< number of pixel formats, DO NOT USE THIS if you want to link with shared libav* because the number of formats might differ between versions }; @@ -546,6 +549,7 @@ enum AVPixelFormat { #define AV_PIX_FMT_GBRAP12 AV_PIX_FMT_NE(GBRAP12BE, GBRAP12LE) #define AV_PIX_FMT_GBRAP14 AV_PIX_FMT_NE(GBRAP14BE, GBRAP14LE) #define AV_PIX_FMT_GBRAP16 AV_PIX_FMT_NE(GBRAP16BE, GBRAP16LE) +#define AV_PIX_FMT_GBRAP32 AV_PIX_FMT_NE(GBRAP32BE, GBRAP32LE) #define AV_PIX_FMT_BAYER_BGGR16 AV_PIX_FMT_NE(BAYER_BGGR16BE, BAYER_BGGR16LE) #define AV_PIX_FMT_BAYER_RGGB16 AV_PIX_FMT_NE(BAYER_RGGB16BE, BAYER_RGGB16LE) -- 2.47.2 _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
