[PATCH v9 6/6] media: verisilicon: VP9: Only propose 10 bits compatible pixels formats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When decoding a 10bits bitstreams VP9 driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.
