New VdpYCbCr Formats VDP_YCBCR_FORMAT_Y_U_V_444 and, VDP_YCBCR_FORMAT_Y_UV_444 have been added in VDPAU with libvdpau-1.2 to be used in get/putbits for YUV 4:4:4 surfaces. Earlier mapping of AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_YV12 is not valid.
Hence this Change maps AV_PIX_FMT_YUV444P to VDP_YCBCR_FORMAT_Y_U_V_444 to access the YUV 4:4:4 surface via read-back API's of VDPAU. --- Changes v1 -> v2: Put the newly added code under #ifdef to avoid build breakage if compiled with older vdpau headers. --- libavutil/hwcontext_vdpau.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/libavutil/hwcontext_vdpau.c b/libavutil/hwcontext_vdpau.c index c11c3cfdab..6b8c1d5f76 100644 --- a/libavutil/hwcontext_vdpau.c +++ b/libavutil/hwcontext_vdpau.c @@ -73,8 +73,10 @@ static const VDPAUPixFmtMap pix_fmts_422[] = { }; static const VDPAUPixFmtMap pix_fmts_444[] = { - { VDP_YCBCR_FORMAT_YV12, AV_PIX_FMT_YUV444P }, - { 0, AV_PIX_FMT_NONE, }, +#ifdef VDP_YCBCR_FORMAT_Y_U_V_444 + { VDP_YCBCR_FORMAT_Y_U_V_444, AV_PIX_FMT_YUV444P }, +#endif + { 0, AV_PIX_FMT_NONE, }, }; static const struct { @@ -349,7 +351,11 @@ static int vdpau_transfer_data_from(AVHWFramesContext *ctx, AVFrame *dst, return AVERROR(EINVAL); } - if (vdpau_format == VDP_YCBCR_FORMAT_YV12) + if ((vdpau_format == VDP_YCBCR_FORMAT_YV12) +#ifdef VDP_YCBCR_FORMAT_Y_U_V_444 + || (vdpau_format == VDP_YCBCR_FORMAT_Y_U_V_444) +#endif + ) FFSWAP(void*, data[1], data[2]); err = priv->get_data(surf, vdpau_format, data, linesize); @@ -400,7 +406,11 @@ static int vdpau_transfer_data_to(AVHWFramesContext *ctx, AVFrame *dst, return AVERROR(EINVAL); } - if (vdpau_format == VDP_YCBCR_FORMAT_YV12) + if ((vdpau_format == VDP_YCBCR_FORMAT_YV12) +#ifdef VDP_YCBCR_FORMAT_Y_U_V_444 + || (vdpau_format == VDP_YCBCR_FORMAT_Y_U_V_444) +#endif + ) FFSWAP(const void*, data[1], data[2]); err = priv->put_data(surf, vdpau_format, data, linesize); -- 2.17.1 ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
