Just replace all FFMIN(255 with av_clip_uint8, should be faster, in theory, on
some platforms.

Just replace all those switches with something line:
if (s->pixel_size == 3)
bytestream2_put_le24(&s->pb, AV_RL24(src));
else
bytestream2_put_byte(&s->pb, src[0]);
4 vs 8 lines.
Also, how do you signal that compression was worse than encoding the frame
directly? In the code you just jump to memcpying the frame to the packet. Does
the decoder just assume if the packet size is the max packet size its
uncompressed?
If so you should check that the compressed stream isn't that same size by some
chance, unless its impossible (e.g. compressed stream is always an odd amount
of bytes or something).
Rest looks fine.
