How to set libva_driver_name in qmake file
-
I am trying build an application using FFMPEG with hardware acceleration.
For that I need to set path for hardware accelerators and libva driver name.export PKG_CONFIG_PATH=/opt/mediasdk/lib/pkgconfig/:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/opt/mediasdk/lib/:$LD_LIBRARY_PATH
export LIBVA_DRIVER_NAME=iHDThese are the path I used to set through Linux terminal.
I am able to set LDD and pkg_config path. But I am able to understand how to set libva_driver_name.Error is ::
"[AVHWDeviceContext @ 0x7f4c18003380] libva: va_getDriverName() failed with unknown libva error,driver_name=(null)
[AVHWDeviceContext @ 0x7f4c18003380] Failed to initialise VAAPI connection: -1 (unknown libva error)." -

libva: va_getDriverName() failed with unknown libva error,driver_name=(null)
should you look for any related issues in the documentation/forum from the libva implementation you're using?

Actually I want to do hardware decoding using FFMPEG in qt. So to enable hardware decoding i need to enable libva drivers ie i965.
So my question is how can I set Libva path and driver name so that when I call ffmpeg api to hardware decode it should take driver. -
what is qmake equivalent to following in cmake
export PKG_CONFIG_PATH=/opt/mediasdk/lib/pkgconfig/:$PKG_CONFIG_PATH
export LD_LIBRARY_PATH=/opt/mediasdk/lib/:$LD_LIBRARY_PATH
export LIBVA_DRIVER_NAME=iHD
