Created attachment 114011 [details] libva-intel-driver: Do not print warnings on stdout Hello, I am currently writing a DXVA2 -> VAAPI wrapper for Wine and noticed that some programs crash with the intel driver while they work flawless with the vdpau wrapper. After some investigation I found out that the intel vaapi driver printed a warning to stdout while the program was using stdin/stdout to communicate with its parent process. The driver simply injected debug messages into this communication. The driver should not use stdout as this pipe is used by a lot of programs to exchange data and should instead print debug messages to stderr. I attached a patch to fix this problem.
