Quoting from: https://ffmpeg.org/trac/ffmpeg/ticket/1718
MP3 parser get the frame_size wrong when playback,
the second and third frame_size are wrong.
On the following samples file:
https://ffmpeg.org/trac/ffmpeg/raw-attachment/ticket/1718/M4A_MP1_288Kbps_CBR_44.1KHz_2ch.m4a,
avprobe changes its output like this:
