Encoding and subsequent decoding with AptX (or AptX HD) results in
incorrect sample rate of output file.
'''Input file''': sine1k.wav - 44100 Hz (16 bit), sinusoidal signal 1000
Hz
'''Decoded file''': sine1k-aptx.wav is labeled as 48000 Hz (16 bit) but in
fact it is 44100 Hz (16 bit) which can be verified by spectral analysis,
it shows 1088 Hz signal instead of 1000 Hz.
How to reproduce:
{{{
ffmpeg -loglevel verbose -i sine1k.wav -acodec aptx sine1k.aptx
ffmpeg -loglevel verbose -i sine1k.aptx sine1k-aptx.wav
ffmpeg version 4.0.2
}}}
