Mans Rullgard 381efba0ec ppc: fix vc1 inverse transform, unbreak build
GCC 4.3 and later are more particular about signedness matching
in vector operations.  The operations under if(rangered) were
missing assignments and thus had no effect.

get_strz is left out becase I want to change it later to return

Ronald S. Bultje f8bed30d8b VC1: merge idct8x8, coeff adjustments and put_pixels.
Merging these functions allows merging some loops, which makes the

Ronald S. Bultje bbfd2e7ab4 VC1: inline vc1_put_block() in vc1_decode_i_blocks().
Advantage is that it allows us to combine several loops into a single
one, and these can eventually be merged into the IDCT itself. Also, it
allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.

Ronald S. Bultje 70aa916e46 VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv().
Advanced profile never uses "range reduction", so vc1_put_block() quite
literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv().
By inlining the function, we can prevent calling IDCT8x8 if
CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the
[0,256] range, but can instead use put_signed_pixels_clamped().

Nicolas George 6741f7c9be ffserver: set the sample aspect ratio
Hi.

It seems that ffserver sets sample_aspect_ratio to an invalid value and lavf
rejects it.

I am not sure what I am doing here, but the attached patch actually solves
something: using the following config:

CustomLog -
NoDaemon
RTSPPort 5454
<Stream test1-rtsp.mpg>
Format rtp
File "/tmp/test1-rtsp.mpg"
</Stream>

it allows a somewhat old ffplay (unaffected by the content-base issue I
spoke of in another thread) to play the stream.

Without it, ffserver logs this and closes the stream:

Wed Feb 16 14:52:14 2011 [rtp @ 0x1399de0]Aspect ratio mismatch between encoder and muxer layer

Regards,
