a0604c6de3 Atrac: DRY a tiny bit of the code down. 2015-11-08 09:04:11 -08:00
Unknown W. Brackets
28a957694a Atrac: Apply second FACT as loop offset. 
It seems like, when these values are different, the difference indicates
some kind of delta in other sample values?

Mostly trying to match values coming out of firmware structs here.

Fixes music looping in Kurohyo 2.

27043b5fa5 Atrac: Do not output remain on ending decode. 
It's not supposed to output 0, or -1, or anything.  It leaves the original
value in place.  This is probably why some games "liked" different values.

9da62c1efc Atrac: Use end codes for remaining when streaming. 2015-11-07 23:30:09 -08:00

959887d407 Atrac: Correct remaining frames return value. 
Streaming buffers still not correct in some cases, primarily looping.

e28fa3c426 Atrac: Correct transition to fully loaded. 
Normally it won't go over of course, oops.

61e530df91 Atrac: Check more buffer states in GetRemainFrame. 2015-11-07 23:30:04 -08:00
Unknown W. Brackets
a932b0858c Atrac: Make sure NO_DATA is always set. 
This way we can move away from data_buf, which eventually we'll stop using
entirely, in preference for PSP RAM.

3f3700cb45 Atrac: Allow games to update buffer state. 
Because they can and do.  This primarily only happens with low level and
SAS streams, I think.

26a81f5179 Atrac: Simplify USE_FFMPEG checks. 
Maybe we should just remove the option, but this way the behavior is a lot
more similar.

3afc86e9b8 Atrac: correct offsetting logic in resetting. 
Probably not super important exactly, but got the numbers backwards when I
reduced the test data.  Oops.

696cb6649e Atrac: Match PSP on reset of streaming data. 
This attempts to match the sizes and positions requested by the PSP
firmware APIs.  The two functions have to match: if they don't, it will
start reading incorrect data.
 2015-11-05 23:23:59 -08:00

4511407506 Atrac: Add reschedule when resetting play pos. 
This matches tests, although the actual delay is more variable.

a2c4f7760a Atrac: Add range check when resetting play pos. 2015-11-05 23:23:50 -08:00
Unknown W. Brackets
91e5916f66 Atrac: Fix sample range check to match output. 
It allows some negative values, actually.

Unknown W. Brackets
2b58af3db5 Atrac: Handle loop samples more correctly. 
They need to be offset same as currentSamples.  Starting to really think
it'd be better to offset currentSamples instead...

Unknown W. Brackets
5cc13c45f4 Atrac: Try to handle endSample more consistently. 
Maybe we should offset currentSample by the firstSampleOffset instead?
 2015-10-25 17:04:25 -07:00

e51891e9cd Atrac: Keep track of PSP-like buffer status. 
This isn't correct yet, but tracking this much fixes looping of certain
audio.

9ea765a347 Atrac: Calculate total samples based on data chunk. 
Not on the entire RIFF size, which will be (slightly) inflated.

ac56eff31c Atrac: Parse the smpl chunk more correctly. 
Returns the same errors as the PSP.
 2015-10-25 17:04:22 -07:00
Unknown W. Brackets
596ecdc431 Atrac: Allow data to extend outside RIFF size. 
This seems technically incorrect, but it's allowed on the PSP, possibly
intentionally due to data shipped truncated by accident?
 2015-10-25 17:04:21 -07:00
Unknown W. Brackets
522a1743f4 Atrac: Return an error if there's no data chunk. 2015-10-25 17:04:20 -07:00

f7fa0a06d4 Atrac: Reset the fileoffset only when adding data. 
Otherwise, it's only a seek.  For example, a seek to 0, as commonly seen.

d0a9813844 Account for uneven sized chunks by rounding up. 
Chunks have an extra pad byte if the size is uneven.  This probably isn't
happening, but just to be safe.

b47458eabb Atrac: fix loading certain savestates. 
Some worked with it that high, but others not.

6420b679d4 Atrac: Split out low-level packet handling. 
So we don't have the hack in the other code at all.

27a10bc49f Atrac: Fix AA3 dataOff value. 
Note: will still be wrong in savestates...
 2015-10-17 16:20:20 -07:00

7d0dd0b94a Atrac: Stop using avio/avformat entirely. 
Probably breaks AA3 support at this point...

679b64ef5a Atrac: calculate instead of using header value map. 
These are knowable values, so there's no real benefit to a static table
except potentially error detection.

eb4ca0cf81 Add a compatibility flag to revert sceAtrac to before #6976. Makes audio work in GTA again. 
Hopefully we will find a better fix in the future.

Also see issue #7863.

ffe7ef1ee2 Avoid spurious warnings in sceAtrac. 
Valkyrie Profile for example calls this, doesn't seem like 0 matters.
