Hi Christian,
Sorry for the delay, I confirm the flush is required with that config
described before. Also in order to only affects that particular I wanted to
do this:
+if (buf->export_refcount > 0)
drv->pipe->flush(drv->pipe, NULL, 0);
But this is not the same kind of vlVaBuffer, so not possible to do that.
But in any case I think you are right we should not need thsi flush at all
so I am ok that you remove this flush. The problem should be elsewhere.
So with your v2 + my change in vlVaAcquireBufferHandle,
This patch is:
