9d2dd356c2 adx: rename ff_adx_decode_header() to avpriv_adx_decode_header()
It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.

27360ccc5e adx: add an ADX parser.
This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.

b237248e29 adx: calculate correct LPC coeffs
Instead of using fixed coefficients, the correct way is to calculate the
coefficients using the highpass cutoff frequency from the ADX stream header
and the sample rate.

ca9e4727ba adx: fix the data offset parsing in adx_decode_header()
first 2 bytes are 0x80, 0x00. offset is only 16-bit.
this is according to format descriptions on multimedia wiki and wikipedia.

e7e2df27f8 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as
hidden.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
