the attached example adds 72 lines it removes none so its not less code.
it is code duplication and more code.
Please stop sending such messy patches, they waste both of our time.
yes sure i could do the extra work and fix your patch before trying to review
it but a submited change should show the change, this does not. it does NOT
contain the removed code because you "forgot" to remove it.
As it is theres no way this could be reviewed let alone tested in libav*
A change needs to show the old and new to be reviewable.
Before submiting more patches please make sure every individual patch
1. NO unreachable code (except when it is seperat and has a clear API)
2. NO code duplication
3. NO function ever must behave different from how it is documented.
If you change a functions behavior change the docs as well.
If you want to split a patch and by doing so violate one of above DONT split
it only makes the patches worse
