Compression format AVHuff not supported
@edc71 you're right. I could add AVHuff support for sure but I have to find a way to not bloat too much libchdr which is meant to be easily embeddable in other projects with a small footprint.
Could always be optional support. If compiled with support, include requisite lib. That way it's available for projects that need it, but doesn't muss up those that don't. Though I suppose that does run contrary to recent efforts to make libchdr more uniform. Hrm.
I agree with you @Sanaki meanwhile I had a look at AVHuff, hopefully it only depends on (possibly) flac which is already in through dr_flac and some huffman decoder so that's not a lot of code. Worth having a look implementing it. @edc71 what's the typical use case ? Daphne / Hypseus Singe ?
Seems like it, though I asked him to open this issue when the topic arose while looking at usage of libchdr with RomVault for data validation purposes. Obviously MAME would be a use case, though I'm not sure under what circumstances this library would come into use with it offhand.

Its actually for a tool which enters rominfo into a database. But hashing chd isnt enough, because the dats are using different hashes. So I needed something simple to include. And also like Sanaki said, it is also been looked at for usage in RomVault
Okay. I will start a dev branch to add it. I also want to fix a bad warning (wrong free) and bump lzma so timing is good.
Will ping you and hypseus singe devs when done.
