Errors-To: ffmpeg-devel-bounces@ffmpeg.org Sender: "ffmpeg-devel" From: LongChair This adds hardware decoding for h264 / HEVC / VP8 using MPP Rockchip API. Will return frames holding an AVDRMFrameDescriptor struct in buf[0] that allows drm / dmabuf usage. Was tested on RK3288 (TinkerBoard) and RK3328. Changes from Previous patch : - Frame colorspace info is now filled. - Frame interlacing is now filled (Note : currently had a bug in mpp which will be fixed soon by rockchip, will set the frame to progressive). - hw_frame_context returns none as format for the rockchip specific 10 bits. - Added support for MPEG4 codec - Added support for VP9 codec. - the ION format has been kept for MPP init (rather than DRM) as this is the only one working right, using DRM format will cause assertions upon close. - Other minor comments have been taken into account --- Changelog | 1 + configure | 16 ++ libavcodec/Makefile | 5 + libavcodec/allcodecs.c | 5 + libavcodec/rkmppdec.c | 584 +++++++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 611 insertions(+) create mode 100644 libavcodec/rkmppdec.c diff --git a/Changelog b/Changelog index 189a803..ccf78b2 100644 --- a/Changelog +++ b/Changelog @@ -44,6 +44,7 @@ version : - drop deprecated qtkit input device (use avfoundation instead) - despill video filter - haas audio filter +- Rockchip MPP hardware decoding version 3.3: - CrystalHD decoder moved to new decode API diff --git a/configure b/configure index 3ba27c5..cbff908 100755 --- a/configure +++ b/configure @@ -314,6 +314,7 @@ External library support: --disable-nvenc disable Nvidia video encoding code [autodetect] --enable-omx enable OpenMAX IL code [no] --enable-omx-rpi enable OpenMAX IL code for Raspberry Pi [no] + --enable-rkmpp enable Rockchip Media Process Platform code [no] --disable-vaapi disable Video Acceleration API (mainly Unix/Intel) code [autodetect] --disable-vda disable Apple Video Decode Acceleration code [autodetect] --disable-vdpau disable Nvidia Video Decode and Presentation API for Unix code [autodetect] @@ -1545,6 +1546,7 @@ EXTERNAL_LIBRARY_VERSION3_LIST=" libopencore_amrnb libopencore_amrwb libvo_amrwbenc + rkmpp " EXTERNAL_LIBRARY_GPLV3_LIST=" @@ -2774,6 +2776,8 @@ h264_qsv_decoder_deps="libmfx" h264_qsv_decoder_select="h264_mp4toannexb_bsf h264_parser qsvdec h264_qsv_hwaccel" h264_qsv_encoder_deps="libmfx" h264_qsv_encoder_select="qsvenc" +h264_rkmpp_decoder_deps="rkmpp" +h264_rkmpp_decoder_select="h264_mp4toannexb_bsf" h264_vaapi_encoder_deps="VAEncPictureParameterBufferH264" h264_vaapi_encoder_select="vaapi_encode golomb" h264_vda_decoder_deps="vda" @@ -2789,6 +2793,8 @@ hevc_qsv_decoder_deps="libmfx" hevc_qsv_decoder_select="hevc_mp4toannexb_bsf hevc_parser qsvdec hevc_qsv_hwaccel" hevc_qsv_encoder_deps="libmfx" hevc_qsv_encoder_select="hevcparse qsvenc" +hevc_rkmpp_decoder_deps="rkmpp" +hevc_rkmpp_decoder_select="hevc_mp4toannexb_bsf" hevc_vaapi_encoder_deps="VAEncPictureParameterBufferHEVC" hevc_vaapi_encoder_select="vaapi_encode golomb" mjpeg_cuvid_decoder_deps="cuda cuvid" @@ -2812,6 +2818,7 @@ mpeg4_cuvid_decoder_deps="cuda cuvid" mpeg4_mediacodec_decoder_deps="mediacodec" mpeg4_mmal_decoder_deps="mmal" mpeg4_omx_encoder_deps="omx" +mpeg4_rkmpp_decoder_deps="rkmpp" mpeg4_vdpau_decoder_deps="vdpau" mpeg4_vdpau_decoder_select="mpeg4_decoder" mpeg_vdpau_decoder_deps="vdpau" @@ -2828,10 +2835,12 @@ vp8_cuvid_decoder_deps="cuda cuvid" vp8_mediacodec_decoder_deps="mediacodec" vp8_qsv_decoder_deps="libmfx" vp8_qsv_decoder_select="qsvdec vp8_qsv_hwaccel vp8_parser" +vp8_rkmpp_decoder_deps="rkmpp" vp8_vaapi_encoder_deps="VAEncPictureParameterBufferVP8" vp8_vaapi_encoder_select="vaapi_encode" vp9_cuvid_decoder_deps="cuda cuvid" vp9_mediacodec_decoder_deps="mediacodec" +vp9_rkmpp_decoder_deps="rkmpp" vp9_vaapi_encoder_deps="VAEncPictureParameterBufferVP9" vp9_vaapi_encoder_select="vaapi_encode" wmv3_crystalhd_decoder_select="crystalhd" @@ -6032,6 +6041,13 @@ enabled openssl && { use_pkg_config openssl openssl/ssl.h OPENSSL_init check_lib openssl openssl/ssl.h SSL_library_init -lssl32 -leay32 || check_lib openssl openssl/ssl.h SSL_library_init -lssl -lcrypto -lws2_32 -lgdi32 || die "ERROR: openssl not found";
