This is large enough for all jpeg2000 files i tested. If some need more then this
should be changed to dynamic allocation. Dynamic allocation would need to be done
carefully as these are many relatively small arrays so repeatly reallocating them
would not be good.
The decrease is a clean and simple solution assuming it works for all files.

They don't modify AVCodec, no needs to call it at register. They will be
wasteful if these codecs are unused. Instead, call static data initialization
at codecs' init.

old: 51281340 decicycles in avcodec_register_all, 1 runs, 0 skips
new: 6738960 decicycles in avcodec_register_all, 1 runs, 0 skips

lavc: add profiles to AVCodecDescriptor
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
|

The profiles are a property of the codec, so it makes sense to export
them through AVCodecDescriptors, not just the codec implementations.
