a naive first approach would be to do (psedocode)
def mycallback(fname):
texture = get_texture_for_fname() # if using resources thats easy
texture.delete()
set_texture_for_fname(fname) # probably easy if using resources
But, a second look point to the really big problem: if the texture is used
in a batch, the batch's draw_list must need regeneration. So, a texture
would need references to all batchs where it is used.
I think you need to approach this at higher level than pyglet, something
like:
class Actor(...):
...
def cbak_media_change(self,...):
# reload the texture, as in naive approach
...
# take care of propagating changes; like batch's draw_list
regeneration
...
