iam trying to implement what you want but iam hitting a wall here
there really are so many things filled in and you clearly do want many
to be kept. I cant read your mind, please say clearly which values you
want not to be filled in by lavf?

please correct below:
pts/dts:                    no
frame boundaries:           no
start_time:                 ?
file duration:              ?
packet duration:            (pretty much meaningless without parsers)
stream array:               yes
extradata:                  (unreliable without parsers)
fps:                        (unreliable without parsers)
values that need decoding:  (unreliable without parsers)
