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:
frame boundaries: no
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)
