67cc09416f decoder/dsf: implement seeking 2014-08-23 14:00:38 +02:00
Max Kellermann
f2a75fbfc7 decoder/dsf: refactor the main decoder loop 
Check for STOP before decoding the first chunk.  This reduces the
command latency.

b1fb09e183 decoder/dsf: make the buffer more local 
This allows the compiler to discard buffer contents between two
iterations.

1f642238a7 decoder/dsf: don't skip remaining bytes 
Nobody cares.

6fe06cad98 decoder/dsf: count the blocks, not the remaining bytes 
Prepare refactoring the whole plugin to use blocks instead of bytes.
A block is the smallest addressable unit, and it will simplify the
seeking code.

2335fdbb5a decoder/dsf: allow channel setups other than stereo 
This finishes the multi-channel support.  Development of the feature
was started with commit 02cc77cd8

1b6f7c3eb7 decoder/dsf: eliminate another hard-coded stereo mode assumption 
When calculating the upper bound using the "sample count" format
header, don't assume it's stereo.

02cc77cd82 decoder/dsf: fix multi-channel files 
The plugin was horribly bugged for files that were not stereo.

d8782ce5fd decoder/dsf: simplify dsf_to_pcm_order() 
Don't pass the buffer size to the function, as it's known at compile
time.  Use "restrict" on the pointer arguments, and merge the two
loops, which allows the compiler to optimize this loop with a few SSE2
instructions.

dedc2986c6 decoder/dsf: fix noise at end of malformed file 
Read one block at a time.  This discards the last partial block, which
cannot be interleaved anyway.  Previously, uninitialised memory was
used to interleave the last block, which generated some noise.

74cdc0005a decoder/dsf: eliminate temporary buffer 
Convert into a second buffer that gets passed to decoder_data()
without copying back to the first buffer.

57cbcdf2ec decoder/dsf: make the "scratch" buffer local 
This allows the compiler to discard buffer contents between two
function calls.

23dce21647 decoer/dsf: fix endless loop on malformed file 
When the data chunk size is not a multiple of the frame size, the last
partial frame lead to an endless loop.  We fix this by checking
chunk_sze>=frame instead of chunk_sze>0.  This way, the partial frame
is simply skipped.

d87cf5146e InputStream: CheapSeeking() returns false only for HTTP 
Seeking on NFS or SMB is cheap.  Actually, only HTTP streams are
expensive to seek.  This enables a few features on NFS/SMB files, for
example Ogg tags.

43a1a0f3ab decoder/faad: remove size!=0 check 
Since we already checked InputStream::KnownSize(), we can assume that
GetSize() returns a valid value, and this check is obsolete.

runtime.
