media: uapi: HEVC: Change pic_order_cnt definition in v4l2_hevc_dpb_entry

2022-08-17T12:41:06+00:00

[ Upstream commit c4a179c7167ee16aad1267f9c99bc1ecff475585 ] The HEVC specification describes the following: "PicOrderCntVal is derived as follows: PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb The value of PicOrderCntVal shall be in the range of −2^31 to 2^31 − 1, inclusive." To match with these definitions change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val. Change v4l2_ctrl_hevc_slice_params->slice_pic_order_cnt to __s32 too.

Two labels used _ instead of - so were never found and one new PIX_FMT was missing the label altogether.

There is no hardware which can filter input on the duty cycle, so no driver implements this. On top of that, LIRC_CAN_SET_REC_DUTY_CYCLE has the same value as LIRC_CAN_MEASURE_CARRIER (0x02000000). Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

The reference_mode derived syntax is part of the compressed headers and should have been moved into the corresponding control structure. Document this mistake. The value can be set to 0 if the driver does not require compressed headers information.
