Summary: EZ-KIT BF 527: VLC cannot play mp3 file

Details:

Hi,

mp3play can play mp3 file, vlc cannot.

I tried with 3 different mp3 files with same result.

Opening online radio leads to the same result.

root:/> vlc toto.mp3

VLC media player 0.8.6b Janus

starting VLC root wrapper... using UID 0 (root)

***************************************

* Running VLC as root is discouraged. *

***************************************

It is potentially dangerous, and might not even work properly.

Remote control interface initialized. Type `help' for help.

status change: ( new input: toto.mp3 )

status change: ( audio volume: 256 )

status change: ( play state: 1 )

[00000224] access_file access error: read failed (Bad address)

Thanks,

David

Tested on both 2008R1.5 and SVN trunk on BF537-STAMP, it seems VLC cannot play

mp3 correctly. VLC broken? Or I am not using VLC correctly?

From the debug message:

"[00000227] main decoder debug: no aout present, spawning one

[00000228] main audio output debug: looking for audio output module: 1

candidate

[00000228] main audio output debug: using audio output module

"dummy"

It looks VLC is not enable any audio output module. So -- we just cannot play

any audio?

--- Mike Frysinger 2009-01-08 03:47:30

look in the vlc plugin dir to see what audio modules you actually have

--- Yi Li 2009-01-08 04:13:28

Thanks Mike.

It looks VLC does not build any audio_out plug-in. May need to configure VLC to

build audio_out plugins.

root:/> ls /usr/lib/vlc/

access control packetizer video_output

access_output misc stream_out visualization

codec mux video_filter

--- Yi Li 2009-01-08 05:10:22

Configure VLC to build oss and alsa audio_output plugin. Fixed in svn trunk and

tested on bf537-stamp (ad1836 plays mp3 files on SD card).

--- Yi Li 2009-01-20 23:19:38

fixed and close.
