Thank you for this wonderful work.
It's great to be able to generate ProRes file right within FFMPEG!
May I ask you a question regarding your encoder?
As a newbie developer, please forgive me if I'm wrong.
But while going though your code,
I saw that the image data is always handled as uint8_t.
Does this mean, that the encoder only supports 8bit per channel?
For example, when I read the "static int encode_slice_plane()" function,
I see that the pointer *src is handled as uint8_t.
Is my interpretation correct that this means
that only 8 bits per channel are supported?
And If yes, is it possible to implement 10 bit encoding?
Thank you for your assistance.
