lavu/pixfmt: add AV_PIX_FMT_RGBA128 This format is useful for doing certain lossless transforms on images, RCT in particular, which require you to escalate the size from 16 to 32 bits to avoid overflows. APIchanges will be done alongside when comitting. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=281bba1d26a4e98ea7848a402588d9c2e9934bf6 --- libavutil/pixdesc.c | 27 +++++++++++++++++++++++++++ libavutil/pixfmt.h | 5 +++++ tests/ref/fate/imgutils | 4 ++++ tests/ref/fate/sws-pixdesc-query | 11 +++++++++++ 4 files changed, 47 insertions(+) diff --git a/libavutil/pixdesc.c b/libavutil/pixdesc.c index e73600f208..7b63d1d7b0 100644 --- a/libavutil/pixdesc.c +++ b/libavutil/pixdesc.c @@ -2828,6 +2828,33 @@ static const AVPixFmtDescriptor av_pix_fmt_descriptors[AV_PIX_FMT_NB] = { .flags = AV_PIX_FMT_FLAG_RGB | AV_PIX_FMT_FLAG_FLOAT | AV_PIX_FMT_FLAG_ALPHA, }, + [AV_PIX_FMT_RGBA128BE] = { + .name = "rgba128be", + .nb_components = 4, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 0, 16, 0, 0, 32 }, /* R */ + { 0, 16, 4, 0, 32 }, /* G */ + { 0, 16, 8, 0, 32 }, /* B */ + { 0, 16, 12, 0, 32 }, /* A */ + }, + .flags = AV_PIX_FMT_FLAG_BE | AV_PIX_FMT_FLAG_RGB | + AV_PIX_FMT_FLAG_ALPHA, + }, + [AV_PIX_FMT_RGBA128LE] = { + .name = "rgba128le", + .nb_components = 4, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 0, 16, 0, 0, 32 }, /* R */ + { 0, 16, 4, 0, 32 }, /* G */ + { 0, 16, 8, 0, 32 }, /* B */ + { 0, 16, 12, 0, 32 }, /* A */ + }, + .flags = AV_PIX_FMT_FLAG_RGB | AV_PIX_FMT_FLAG_ALPHA, + }, [AV_PIX_FMT_P212BE] = { .name = "p212be", .nb_components = 3, diff --git a/libavutil/pixfmt.h b/libavutil/pixfmt.h index 21564b97ff..901afbaed3 100644 --- a/libavutil/pixfmt.h +++ b/libavutil/pixfmt.h @@ -451,6 +451,9 @@ enum AVPixelFormat { AV_PIX_FMT_RGBF16BE, ///< IEEE-754 half precision packed RGB 16:16:16, 48bpp, RGBRGB..., big-endian AV_PIX_FMT_RGBF16LE, ///< IEEE-754 half precision packed RGB 16:16:16, 48bpp, RGBRGB..., little-endian + AV_PIX_FMT_RGBA128BE, ///< packed RGBA 32:32:32:32, 128bpp, RGBARGBA..., big-endian + AV_PIX_FMT_RGBA128LE, ///< packed RGBA 32:32:32:32, 128bpp, RGBARGBA..., 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 };
