FLAC 1.2.0 released

FLAC 1.2.0 is out.  There are a few new features and some speedups and fixes, but more importantly, there are some small changes to the decoder to pave the way for possible future compression improvements, so applications developers are encouraged to upgrade (the API has not changed).  The changelog has all the details, but in summary:

- automatic SSE OS detection at runtime (so no need to specifically enable SSE at compile time)
- small encoder and decoder speedups
- new --ignore-chunk-sizes option in flac will help with fb2k piped encoding to flac.exe

do you mean that the problem about reaching the maximum seek points in the file is gone?

Yes, though you will need to manually update the parameters string for converter (make a custom preset) and tell fb2k developers it would be great to change the FLAC preset on occasion.

v1.2.0 "--ignore-chunk-sizes" seems to not create any seek point. Is it safe for decoder compatibility?

And I found the last FLAC takes more CPU cycle to seek with long flac files (55 minutes - 400MB).

I don't understand - what are those, if not seekpoints?

Other blocks allow for padding, seek tables, tags, cuesheets, and application-specific data. There are flac options for adding PADDING blocks or specifying seek points. FLAC does not require seek points for seeking but they can speed up seeks, or be used for cueing in editing applications.

My question also is solved. >Is it safe for decoder compatibility?

I still don't understand what you meant. I have read the format documentation many times, and as far as I know, those are seekpoints... Am I so tired that I am missing something? 

Sorry, I made mistake. What I meant was:
v1.2.0 "--ignore-chunk-sizes" seems to not create any seek point.

Wow, two new versions of lossless codecs released within half a day.

That calls for an updated comparison chart...

Tell me about it.

I'm hoping to run my tests this weekend, when I know the PC will be free.

seekpoints are not required but can improve seek times.  with --ignore-chunk-sizes, a seektable is currently not added.  in the future I plan to have the encoder go back and add one after encoding is finished and it knows the total number of samples.  a workaround in the meantime is to add a seektable afterwards with metaflac.

Quote from: Seiitsu on
Exactly... why? I assume backwards compatibility should not be a problem at this time at least since the decoder was updated for future possible compression improvements.
a 1.2.0 decoder will be able to decode any 1.2.x streams, so upgrading now means not having to when 1.2.x encoder improvements come out.  the FLAC 1.1.x series spanned 4.5 years.

yes, this should be the norm now that I have my own nsi script.

speaking of which, FLAC and WavPack encode at the same speed by default but have different ratings on the wiki.

Thanks for the new version! I'm just wondering: why that version numbering jump (1.1.x -> 1.2.x) ?

There's a compile on Rarewares as well, if that's easier.
