this filter is the same as showspectrum but with constant Q transform,
so frequency is spaced logarithmically

adpcm_ima_qt does not produce reproducible results, so it is temporarily
disabled (see #3701).

An invalid entry already has the property of having a negative number
of bits, so remove the check on the reserved value, and rearrange the
code as a consequence.

  avconv: Report the codec and the encoder separately
Merged-by: Michael Niedermayer <michaelni@gmx.at>

Avoid buffer overruns when processing some MOV files with the amerge
filter. Files produced by Adobe Premiere Pro CC have up to one second of audio
not interleaved. With common settings (<= 48kHz) that makes up to 47 frames so
a queue length of 64 makes sense.

Fixes ticket #3510.

When the joint table does not contain a valid entry, the decoding restarts
from scratch. By implementing the trick of jumping to the 2nd level of the
individual table (and inlining the whole), a speed improvement of 5-10%
is possible.

This allows the caller to write all buffered data to disk, allowing
the caller to know at what byte position in the file a certain
packet starts (any packet written after the flush will be located
after that byte position).
