[Mesa-dev] [PATCH 7/9] st/va: add enviromental variable to disable interlace

[Christian König]

From: Boyuan Zhang 

Add environmental variable to disable interlace mode. At VAAPI decoding stage, 
driver can not distinguish b/w pure decoding case and transcoding case. And 
since interlace encoding is not supported, we have to disable interlace for 
transcoding case. The temporary solution is to use enviromental variable to 
disable interlace mode.
