When built with gcc 4.6, the MMX rgb24 to yuv conversion gives
wrong output. The compiler produces this warning:
libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated
Changing the memory operand to a register makes it work.

In the FAQ section "How do I encode single pictures into movies?", use
-s for generating symbolic links with the ln command.
The script was generating hard links, which is not likely what it was
supposed to do.

This is used for mapping AVStreams back to their corresponding
RTSPStream. Since d9c0510, the RTSPStream pointer isn't stored in
AVStream->priv_data any longer, breaking this mapping from AVStreams
to RTSPStreams.
Also, we don't need to clear the priv_data in rdt cleanup any longer,
since it isn't set to duplicate pointers.

The early disabling of irrelevant arch extensions is no longer
required, and removing it makes dependencies involving these

s->windowed_samples will always have a range of [-32767,32767] due to the
window function, so the return value from log2_tab() will always be in the
range [0,14].

This code will be later split out into a function which takes a 'size'
argument, so I'm keeping the name 'sizeX' here.

Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.

The function return type is void, so a return statement with an
