Too many logs in the va initialization

[hongbolv]

When every process initializes the media driver, there are always fine lines log in the terminal. In the server side, if we have multiple channels, the log size will increase to n*5 lines. Then it is not easy to find the useful log.

@hongbolv , what you mentioned is these log? libva info: VA-API version 1.13.0 libva info: User environment variable requested driver 'iHD' libva info: Trying to open /home/intel/carl/open_driver/build/media_driver/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_13 libva info: va_openDriver() returns 0

@XinfengZhang I see the same logs during my gstreamer app initialization. Is there some env var should I use to disable this output?

yes, you could use LIBVA_MESSAGING_LEVEL to set the level, also , there are one discussion about default message level https://github.com/intel/libva/pull/564
