[vlc] Re: VLC 0.8.0 and Windows CE

[Rick Davis]

Gildas,

	Am I missing something here? Is VLC looking for an mpga->float32
converter? I don't see any in the source. Is something missing causing it to
try to use it? I am to say the least, confused.

Everything seems to be allright except that you are missing 2 plugins. The
mpeg audio decoder (libmad_plugin which uses the mad library) and the mpeg
video decoder (liblibmpeg2_plugin which uses the libmpeg2 library).

This indicates that you are missing the mpeg video decoder plugin 
(liblibmpeg2_plugin). You'll need to get libmpeg2 and compile it before you 
can compile this plugin.

The WAVERR_BADFORMAT is actually not a problem here. It happens during the 
probing phase and just signals that your soundcard doesn't support the 
float32 format (but it does support s16 pcm so you're fine there).

Ok, so the audio output plugin is started correctly but as stated above you 
are missing the mpeg audio decoder plugin (libmad_plugin), hence the 
"couldn't find filter for the conversion" problem.
Compile this and that will solve this problem (you'll need to get and 
compile libmad first).

Everything else looks fine.
