flv containing AAC 48 kHz interpreted as 44.1 kHz
according to the flv spec ( http://www.adobe.com/content/dam/Adobe/en/devnet/flv/pdfs/video_file_format_spec_v10.pdf ), if the audio track is reported as AAC 44 kHz, "the Flash Player ignores these values and extracts the channel and sample rate data is encoded in the AAC bitstream."
however, when I play a flv file with 48 kHz AAC, VLC 2.1.5 on verbosity=2 talks only about 44100 Hz.
most importantly, audio drops out every ~second for a bit, which sounds like 44100 of 48000 samples are decoded and the remaining ones are 0.
