No sound on a clip that plays perfectly in VLC and ffplay

[arrenlex@…]

The clip linked in the URL was recorded from mythtv. It comes from a hardware encoder -- the WinTV HVR 1900.

It plays perfectly in VLC and ffplay, but mplayer produces no sound. The output looks like this (the movie that produces this output is a longer version of the same clip, I simply cut the one I linked to to 10 MB with head -c):

reproduced.

works with mplayer -ss 3 -demuxer lavf

[reimar]

The problem is in mp3lib, e.g. -ac ffmp2 works, too.

[compn]

mp3lib is now marked buggy, meaning ff decoders are higher priority. closing bug...
