Subject: [Qemu-devel] [PATCH 12/25] audio: unify input and output mixeng buffer management
Date: Sun, 25 Aug 2019 20:46:14 +0200
Message-ID: <2a8d0b8e4134a88d6389f3d9cdb4ac30840889f6.1566755452.git.DirtY.iCE.hu@gmail.com> (raw)
In-Reply-To: <cover.1566755452.git.DirtY.iCE.hu@gmail.com>

Usage notes: hw->samples became hw->{mix,conv}_buf->size, except before
initialization (audio_pcm_hw_alloc_resources_*), hw->samples gives the
initial size of the STSampleBuffer.  The next commit tries to fix this
inconsistency.
