MPP+DRM: low level API for video codecs and display (also 4k UHD+HDR+HLG) - mcerveny - 01-27-2018
Hello.
I prepared and tested "mpi_dec.c" application to test low level access hardware accelerated video decoders for everyone interested
.You can use this application as benchmark and feature tester of your Rock64 (not video player).
There are few sample results of not PTS synchronized maximum speed decoding and display (min CPU freq set 1008MHz and DDR set to 933MHz and decoder set to 600MHz, testing videos are mostly "Big Buck Bunny"):
Code:
Format Decoder Avg result (FPS)
1080p60 hevc 310
1080p60 h264 251
2160p30 h264 64
2160p60 hevc 76
2160p60 h264 65
2160p60hdr hevc 57
2160p60hdr/hlg hevc 70Source for "mpi_dec.c" and detailed description is https://github.com/mcerveny/utils. There are many hints to check if playing hardware accelerated video. You can also study issues (for Kodi/Plex/LibreELEC) like Kwiboo/linux-rockchip#22.
Happy hacking and buy me a Beer.
