Subject: Re: [RESEND PATCH v0 5/5] wave5 : Fixed the wrong buffer size
formula.
Hi,
Le mercredi 31 janvier 2024 à 10:30 +0900, jackson.lee a écrit :
> 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.
This patch will go away as soon as you have ported to v4l2-common as requested
in patch 1/5. It will also make future addition of pixel formats less tedious.
regards,
Nicolas
