Here's a somewhat experimental patch with a new AVOption
write_keyframe_palette that allows you to write the palette to every

contains palette changes.
It is needed in order to switch palette properly when seeking, that is.
It's interesting to note that Windows Media Player doesn't need xxpc
chunks at keyframes in order to seek properly in the following original
file from Sierra's King's Quest VI. I have of course no idea how they
solve that.
This original file doesn't work properly in FFplay for some reason. It
generates "stream_ptr out of bounds" messages at the locations of the
xxpc chunks.

It seems it has something to do with the index, since if I copy it to a
new file with the last part cut off (incorrect but it will play at
least), those "stream_ptr out of bounds" messages will disappear, and
the palette changes will occur as expected.
