1)
>>All of these should be size_t
The field type is still "int" according to James Almer's comment.
2) I placed the fields at the very end, according to a message from Timo
Rothenpieler.
3)
>>The semantics of these new fields definitely need to be defined more
precisely
Added a flag responsible for the behavior(enum
CONTAINER_CROPPING_POLICY_TYPE container_apply_cropping;).
When set to 1 (the default), libavcodec will apply container cropping
to codec cropping additionally.
When set to 2, libavcodec will use container cropping to overwrite
codec cropping (the final cropping uses container cropping parameters)
When set to 0, libavcodec will ignore container cropping parameters
(the final cropping uses codec cropping parameters)This field works with
"apply_cropping".
Only if apply_cropping is 1, this field works
