Alexandre Courbot 8e61bb9037 virtio: video: decoder: ffmpeg: use zero-copy for input buffers ... Use the newly introduced AvBufferRef of our ffmpeg crate to give transfer ownership of the input mapping to libavcodec and avoid a copy of the input data. libavcodec will drop our input buffer when it is done with it, which will make it automatically send the NotifyEndOfInputBuffer to signal it can be reused. BUG=b:169295147 TEST=v4l2r's simple_decoder can decode a H.264 stream.
