[Ffmpeg-devel] FLV files have no sound

[Alexander Mitev]

Hello! 
I just built ffmpeg for myself under Windows, and tried to convert an AVI file with sound
to FLV. The video is OK, but there is no sound in the resulting file. 
Here are the results that ffmpeg produces: 



 ffmpeg -i test.avi -ab 128 -ar 44100 -b 500 -r 15 -s 320x240 test.flv

If I try to copy the original audio, it produces the following results:

[NULL @ 00782300]flv doesnt support that sample rate, choose from (44100, 22050,

11025)
Could not write header for output file #0 (incorrect codec parameters ?) 

Can you please help me? 
I can send you the original AVI file for testing purposes.
Regards, Alex
