7e06e0ede3 dca: use EXT_AUDIO_ID field to determine core extensions 
This avoids the core substream extensions scan when the EXT_AUDIO_ID
field indicates no extensions or only unsupported extensions. The scan
is done only if the value of EXT_AUDIO_ID is unknown or indicates a
present XCh extension which we can decode.

8311150620 Make FF_DEBUG_DCT_COEFF output coeffs via av_log() instead of just via AVFrame. 
This allows the values to be used without changing C code and is closer to how
the other DEBUG flags work.
If this causes a problem for any user of this flag, please tell me and
ill split the flag in 2.

Advantage is that it allows us to combine several loops into a single

allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.

a8858ee11c 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().
