[xine-user] xine_get_next_audio_frame not working

[Noam H. <noa...@gm...>]

I am trying to use xinelib for decoding files and reencoding them.
while xine_get_next_video_frame works ok, I can't get
xine_get_next_audio_frame to work.
the frame.data point is either 0 or invalid. also
(audio_buffer_t*)frame.xine_frame contains strange data.
I am using xine 1.0.2 on redhat enterprise linux 3,  2.4.21-17.ELsmp
#1 SMP, gcc 3.2.3

Thanks,
noam
