[ Upstream commit309373a357] The payload size for encoder capture buffers is set by the driver upon finishing encoding each frame, based on the encoded length returned from hardware, and whatever header and padding length used. Setting a non-zero default serves no real purpose, and also causes issues if the capture buffer is returned to userspace unused, confusing the application. Instead, always set the payload size to 0 for encoder capture buffers when preparing them.
