0a0f7ecc16 videomixer: Use movzbl instead of movzxb for moving one byte to a l register 
For some reason latest gcc/binutils accept movzxb here while
movzbl would be correct and is the only thing accepted by older
gcc/binutils.

Fixes bug #604679.

cd2b1c1b58 audiofxbasefirfilter: Add special processing functions for Mono/Stereo 
This provides another 7% speedup for the time domain convolution and 1.5%
speedup for the FFT convolution on Mono input.

This optimization assumes that the compiler simplifies calculations
and conditions on constant numbers and unrolls loops with a constant
number of repeats.

a3d7321c50 audiofxbasefirfilter: Add a "low-latency" mode 
This will always use time-domain convolution, which lowers the latency.
With FFT convolution it's always a multiple of the kernel length,
with time domain convolution it's only the pre-latency of the filter kernel.
 2009-12-15 18:12:46 +01:00

02960383c1 audiofxbasefirfilter: FFT convolution implementation 
This provides a great speedup, especially the relationship between kernel
length and processing size is now logarithmic instead of linear. Below a
kernel size of 32 it's a bit slower, afterwards it's much faster:

17     0.788000 -> 0.950000
33     1.208000 -> 1.146000
65     2.166000 -> 1.146000
...
4097 107.444000 -> 1.508000

For sizes smaller 32 the normal time-domain convolution is chosen,
for larger sizes the FFT convolution is automatically used.

Fixes bug #594381.

ddafc20b28 audiofxbasefirfilter: Make most code parts independent of the processing functions and used convolution algorithm 
Only remaining part is the residue pushing, which will be fixed later.
 2009-12-15 18:12:46 +01:00
Sebastian Dröge
43576fb0cf audiofxbasefirfilter: Optimize time-domain convolution 
Remove some redundant calculations, move comparisions out of
inner loops, etc.

This makes the convolution about 3 (!) times faster but
processing time is of course still proportional to the
filter size.

abb437454e audiofxbasefirfilter: Rewrite timestamp tracking

061ededa36 videomixer: Add MMX implementations of the AYUV blending and color filling functions 
This provides a 20% speedup for blending and 100% for color filling.

The blending can probably be optimized even more.

6c4c8f8670 qtdemux: fix up language code extraction some more 
Quicktime uses ISO 639-2 for language codes, but GST_TAG_LANGUAGE
is supposed to hold a ISO 639-1 code, so convert as needed using
the new API from -base.

See #602126.

b66f914586 matroska: fix language code writing and extraction 
Matroska uses three-letter ISO 639-2B codes, but GST_TAG_LANGUAGE is
supposed to contain two-letter ISO 639-1 codes, so use new language
code mapping functions in -base to convert between those two as
needed.

Fixes #505823.

52177fa056 Revert "qtdemux: Correctly parse classification tags" 
This reverts commit cd883aa60c.

... NULL buffers shouldn't really happen anymore when popping the

and try to get the next possible transport. Fixes playback of RealMedia streams.

7418dee253 videomixer: Only pop buffers from collectpads after they're fully consumed 
This decreases latency and memory usage because new buffers are only
accepted by collectpads if there's no queued buffer.
