For the MP3 part, I'm not sure how to tell if there really is an issue.
I have converted the mp3 file to wav with both ffmpeg and gstreamer, and both
files show the exact same length (0:00:01.071020409 seconds, at 44100 Hz).
It is possible that both gstreamer and ffmpeg drop the same amount of data
though.
Is the mp3 file you included supposed to contain more data than this ?

FWIW, playing with gst, I hear noise at the beginning and end, but that might
be expected since you said you added padding at the end.

Last, mad (the mp3 decoding library used by gst) reports decoding errors at the
end of the stream. Whether it is because of the padding, or because of invalid
data before that padding was added, I do not know).
