d2af7205a1 Use hierarchic names convention (prefix them with av_expr) for the
eval API.

More grep-friendly and more consistent with the rest of the FFmpeg
API.

ebb7f7de82 aaclatm: Eliminate dummy packets due to muxlength calculation.
Muxlength does not include the 3 bytes of AudioSyncStream() before the
AudioMuxElement(). If these three bytes are not accounted for the last three
bytes of the LATM packet are sent back to the decoder again.

Fixes issue244/mux2.share.ts

931856a267 Improve PGS parsing: the "state" field is not relevant to us,
the object number is, it determines whether we should continue
parsing the presentation description and whether we should
clear the subtitles on the next display command.

Previously it was releasing the buffer which was returned to the user,
which was resulting in a crash in case of direct rendering.

00d1e96bf4 H.264 decode: support cropping up to 28 pixels in interlaced mode.
Contrary to progressive, just being able to crop up to 14/15 pixels
is not enough to encode all supported resolutions, and the new
behaviour is also consistent with e.g. MPEG-2 etc.

6c003e6de8 aacdec: pass avctx as logging context for decode_audio_specific_config
Use avctx in all called functions. This allows passing a NULL AACContext
for LATM since the AACContext is only used in output_configure() which
is skipped for LATM parsing.

66a71d989f aacdec: refactor the actual aac decoding code into its own function
aac_decode_frame() remains as AVPacket handling a wrapper. The actual
decoding function takes a GetBitContext as input and will be used be the
AAC LATM decoder to avoid copying the unaligned AAC bitstream.

d56920e206 aacenc: Correct spreading calculation for high spreading.
The 3GPP spec uses the following calculation for high spreading:

thr'_spr = max(thr_scaled, s_h(n) * thr_scaled(n-1))

where, n is defined as the current band, and s_h() is defined as "[...] the
distance of adjacent bands in Bark and a constant slope that is 15 dB/Bark
[...]". This is a little ambiguous as you would assume you want the Bark
width of the previous band for this calculation. However, this assumption
appears to be incorrect, and you really want the Bark width of the current
band. Coincidentally this is exactly what the spec calls for! =P

This noticeably improves Tom's Diner at low bitrates (I tested at 64kbps,
with mid/side disabled).
