From 5de4f1d871d60886b9630531fa8c34cad13cc9dd Mon Sep 17 00:00:00 2001 From: Philip Langdale Date: Mon, 6 May 2019 20:39:39 -0700 Subject: avutil: Add NV24 and NV42 pixel formats These are the 4:4:4 variants of the semi-planar NV12/NV21 formats. These formats are not used much, so we've never had a reason to add them until now. VDPAU recently added support HEVC 4:4:4 content and when you use the OpenGL interop, the returned surfaces are in NV24 format, so we need the pixel format for media players, even if there's no direct use within ffmpeg. Separately, there are apparently webcams that use NV24, but I've never seen one. --- libavutil/pixdesc.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'libavutil/pixdesc.c') diff --git a/libavutil/pixdesc.c b/libavutil/pixdesc.c index fe38344d73..b97b0665b0 100644 --- a/libavutil/pixdesc.c +++ b/libavutil/pixdesc.c @@ -2320,6 +2320,30 @@ static const AVPixFmtDescriptor av_pix_fmt_descriptors[AV_PIX_FMT_NB] = { }, .flags = AV_PIX_FMT_FLAG_PLANAR | AV_PIX_FMT_FLAG_ALPHA, }, + [AV_PIX_FMT_NV24] = { + .name = "nv24", + .nb_components = 3, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 0, 1, 0, 0, 8, 0, 7, 1 }, /* Y */ + { 1, 2, 0, 0, 8, 1, 7, 1 }, /* U */ + { 1, 2, 1, 0, 8, 1, 7, 2 }, /* V */ + }, + .flags = AV_PIX_FMT_FLAG_PLANAR, + }, + [AV_PIX_FMT_NV42] = { + .name = "nv42", + .nb_components = 3, + .log2_chroma_w = 0, + .log2_chroma_h = 0, + .comp = { + { 0, 1, 0, 0, 8, 0, 7, 1 }, /* Y */ + { 1, 2, 1, 0, 8, 1, 7, 2 }, /* U */ + { 1, 2, 0, 0, 8, 1, 7, 1 }, /* V */ + }, + .flags = AV_PIX_FMT_FLAG_PLANAR, + }, }; #if FF_API_PLUS1_MINUS1 FF_ENABLE_DEPRECATION_WARNINGS -- cgit v1.2.3
