>> Namaste to all!
>> I've almost completely rewritten the HAM support now, the new HAM
>> decoder is 70-80% faster than the old one by taking advantage pipelining
>> and precalculated data.
>> I don't use avctx->extradata anymore for the new data structures, I did a small but neat expandable data structure with all data needed just 9 bytes in size.
>> So we can change all relevant data on per frame basis and I already tested masking with it, easy from now on to get it in. ;-)
>> But will supply a separate patch for this one.
>> Have fun reviewing!
> Here's a much better patch!
> The following changes were made with this patch:
> 1. Fixed and updated the documentation a lot.
> 2. Merged lots of duplicate code into a single function
> 3. Rearranged IFF extra context structure of packet
> 4. Fixed a plane line size calculation in IFF-PBM
Since, I've decided to provide a separate patch for step 2 I just resend
the HAM support patch without doing step 2.
