4Subject: [PATCH] videodec: Don't use non-growable pool
5
6As we don't know how many output buffers we need to operate, we need to
7avoid pool that can't grow. Otherwise the pipeline may stall, waiting
8for buffers. For now, we require it to be able to grow to at least
932 buffers, which I think is a fair amount of buffers for decoders.
