c23acbaed4 Don't use ff_cropTbl[] for IDCT. 
Results of IDCT can by far outreach the range of ff_cropTbl[], leading
to overreads and potentially crashes.

This only returns bits per sample when it is exactly correct. That is, the
codec contains only raw samples with no frame headers or padding. This applies
to basically all PCM codecs and a small subset of ADPCM codecs.

51ddf35c90 wmaenc: fix m/s stereo encoding for the first frame 
We need to set ms_stereo in encode_init() in order to avoid incorrectly

5d652e063b wmaenc: check final frame size against output packet size 
Currently we have an assert() that prevents the frame from being too large,
but it is more user-friendly to give an error message instead of aborting on
assert(). This condition is quite unlikely due to the minimum bit rate check
in encode_init(), but it is still worth having.

dfc4fdedf8 wmaenc: require a large enough output buffer to prevent overwrites

1ec075cfec wmaenc: limit allowed sample rate to 48kHz 
ff_wma_init() allows up to 50kHz, but this generates an exponent band
size table that requires 65 bands. The code assumes 25 bands in many
places, and using sample rates higher than 48kHz will lead to buffer
overwrites.

c2b8dea182 wmaenc: limit block_align to MAX_CODED_SUPERFRAME_SIZE 
This is near the theoretical limit for wma frame size and is the most that
our decoder can handle. Allowing higher bit rates will just end up padding
each frame with empty bytes.

Fixes invalid writes for avconv when using very high bit rates.

b087ce2bee g722: Fix the QMF scaling 
This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.

This makes the decoder output have double the magnitude
compared to before.

The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.

790a367d9e Fix parser not to clobber has_b_frames when extradata is set. 
Because in contrast to the decoder, the parser does not setup low_delay.
The code in parse_nal_units would always end up setting has_b_frames
to "1", except when stream is explicitly marked as low delay.
Since the parser itself would create 'extradata', simply reopening
the parser would cause this.

This happens for instance in estimate_timings_from_pts(), which causes the
parser to be reopened on the same stream.

This fixes Libav #22 and FFmpeg (trac) #360

unaligned.
