I want to test the video hardware codecs on the RK3399 to transcode video.
I noticed that ffmpeg is apparently able to access hardware for h.264 and h.265v video.
I installed vainfo and vdpauinfo:
sudo apt-get install vainfo sudo apt-get install vdpauinfo
First I tried running vainfo:
[firefly@firefly] ~ 1182: sudo vainfo
error: XDG_RUNTIME_DIR not set in the environment.
libva info: VA-API version 0.39.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/aarch64-linux-gnu/dri/rockchip_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
Aside from XDR_RUNTIME_DIR not being set the command reports an error regarding the rockchip video driver - as it turns out one isn't installed:
[firefly@firefly] ~ 1183: ls /usr/lib/aarch64-linux-gnu/dri/
./ dummy_drv_video.so r600_drv_video.so
../ nouveau_drv_video.so radeonsi_drv_video.so
A similar library error is reported missing in action when I attempt to use vdpauinfo:
[firefly@firefly] ~cv 1184: sudo vdpauinfo
display: :0.0 screen: 0
Failed to open VDPAU backend libvdpau_rockchip.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1
It's obvious that vainfo knows it's a rockchip device, so that's a good sign. I'm going to look around and see if I can locate a package with the drivers, but I'm wondering if this is the correct approach.
Has anyone else managed to utilize ffmpeg to access the harware video codecs?
