Slow audio in mplayer, it's ok in xine and VLC

[denilsonsa@…]

There is a movie file that plays fine in xine and VLC, but in mplayer the audio is slow. Looks like mplayer detects the audio as 22050Hz, while it should be 48000Hz.

The file is an episode from a TV series. There are 26 episodes (each is a .mkv file of about 260MB). 25 episodes play fine, with correct audio, but 1 has this problem with slow audio.

I suppose you want the file to test it, so here is the torrent:

The file with problem is:

Shadow Raiders War Planets 104 Bad To The Bone [DVDrip].mkv

Here is some relevant portion of mplayer output for a good file:

Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, s16le, 160.0 kbit/10.42% (ratio: 20000->192000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)

And now the same portion for that 104 file:

Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 22050 Hz, 2 ch, s16le, 416.0 kbit/58.96% (ratio: 52000->88200)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)

xine detects this "problematic" file as 48000 Hz at 160 kbit/s

can you upload the first 5 mb of the file?
just start uploading it and stop it after a few minutes

Done. Uploaded it as "bug_1066.mkv".

I've noticed that this incomplete file can't be played in xine, but can be played ok in VLC.

In case you need a bigger portion of the file, just tell me.

looks like a problem with mkv demuxer

well -demuxer lavf is default for mkv files. and your sample works ok in svn for me. detected as 48000.

mplayer mkv demuxer isnt maintained in svn anymore so closing this bug.

oops, well it works with mplayer -afm ffmpeg bug_1066.mkv
seems to be a problem with mp3lib decoder.
probably related to the 'missing header' warnings.
