[PATCH v0 5/5] wave5 : Fixed the wrong buffer size formula.

jackson.lee jackson.lee at chipsnmedia.com
Mon Jan 29 23:20:46 PST 2024


S_FMT/G_FMT should report the buffer size based on aligned width and height.
And, Host can set the real encoding size through s_selection and g_selection.
So, Driver should use the conf_win information for encoding size instead of size of S_FMT/G_FMT.
