vainfo needs sudo on Ubuntu20.04 #444

Open ymaskina opened 4 years ago

ymaskina commented 4 years ago

I faced an issue using libva functions on Ubuntu20.04. Without sudo the output of vainfo will be follow: libva info: VA-API version 1.8.0 libva info: User environment variable requested driver 'iHD' libva info: Trying to open /opt/intel/mediasdk/lib64/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_8 libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed libva info: va_openDriver() returns 18 vaInitialize failed with error code 18 (invalid parameter),exit I found workaround to change owner group of renderD128 from 'render' to 'video' but maybe this problem can be somehow solved on your side. Thanks, Yuliya

so if you add your user id into render group, it will work, right?

@ymaskina Maybe you could try to use the intel-media-driver or the intel-media-driver-non-free package instead of the Intel Media SDK (libva error: /opt/intel/mediasdk/lib64/iHD_drv_video.so init failed)? Trying to use sudo with vainfo leads to failure, at least on GNOME Wayland on my laptop, not to mention that the aforementioned workaround is not needed. Also, as this is presumably a Media SDK issue, shouldn't you be reporting this to https://github.com/Intel-Media-SDK/MediaSDK ?

I need to use Intel Media SDK as it presents in OpenVINO package. I`ll report it to MediaSDK too, thanks

onabiull commented 4 years ago

This is releated to udev rules, managed by OS maintainers. Canonical in this case.

ymaskina commented 4 years ago

@onabiull I just need somebody adds step with chrgp in installation steps if this is really a feature on Ubuntu20 so that customers don`t have problems using libva in OpenVINO package:) Or maybe it can be handled differently.

dvrogozh commented 4 years ago

@ymaskina : this can't be added to the package installation (meaning libva package in any form: the one you get as OS package or you self build and make-install it) steps since this relates to security setup of particular system. Effectively OS manages access rights to the devices via particular groups. This is system administrator responsibility to add user to the required group. If you develop some higher level SDK or framework with some dedicated installation system (separated from distro installation system), then you probably can consider to add such step within this higher level installation (which will be covered by end-user agreement for your SDK/framework). But I don't think we can do add such a step neither for libva nor mediasdk (where under mediasdk I mean just a library distributed w/ the OS).
