Subject: Re: [FFmpeg-devel] [PATCH 2/2] Add vulkan dirac hwaccel
Date: Thu, 15 Aug 2024 08:45:40 +0000
Message-ID: <CAP664DVJJ6=Dt0y0SCBymMvVpmvf1bQQ3VE9NYqFrsAwVDequQ@mail.gmail.com> (raw)
In-Reply-To: <20240814121856.757459-3-mozil.petryk@gmail.com>
RE: [PATCH] Move vulkan_spirv.h and deps to lavutil
Moved spirv_compiler into lavutil to avoid any linking errors.
It's now used in lavc and lavfi, should probably be moved to lavutil
