05418f1687 rtpbin: avoid some structure copies 
Don't make copied in the getter and setter for SDES in the RTPSource. This
avoids a couple of copies of the SDES structure when generating RTCP
packets.

c3448f978e rtpmanager: improve SDES handling

Include all values set in SDES struct when sending RTCP SDES.

4687199348 rtph264pay: add option to insert PPS/SPS in streams 
Add a new spspps-interval property to instruct the payloader to insert
SPS and PPS at periodic intervals in the stream.
Rework the SPS/PPS handling so that bytestream and AVC sample code both use the
same code paths to handle sprop-parameter-sets. This also allows to have the AVC
code to insert SPS/PPS like the bytestream code.

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.

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.

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.

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.

061ededa36 videomixer: Add MMX implementations of the AYUV blending and color filling functions

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.

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.
