Subject: [RFC 3/7] media: uapi: h264: clarify pic_order_cnt_bit_size field
Date: Tue, 23 Jun 2020 15:28:05 -0300	[thread overview]
Message-ID: <20200623182809.1375-4-ezequiel@collabora.com> (raw)
In-Reply-To: <20200623182809.1375-1-ezequiel@collabora.com>

From: Philipp Zabel <p.zabel@pengutronix.de>

Since pic_order_cnt_bit_size is not a syntax element itself, explicitly
state that it is the total size in bits of the pic_order_cnt_lsb,
delta_pic_order_cnt_bottom, delta_pic_order_cnt[0], and
delta_pic_order_cnt[1] syntax elements contained in the slice.
