init_put_byte should never be used outside of lavf, since
sizeof(AVIOContext) isn't part of public ABI.

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().

With negative stride, the start of the edge_emu buffer should be pointing to

With positive stride, pointing to the end of the buffer was completely wrong.

Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic. These include clang and some BSD versions.
All AVX code will be written for yasm, where the main assembler
is not involved.

On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files. This is generally bad, as most of these
functions are smaller inlined than not.

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:
