[FFmpeg-user] Problem with decoding an MP3 stream introduced after April 6th

[Dennis Volodomanov]

Hello all,

The build on April 6th was decoding an MP3 stream just fine, but some 
time after that it broke unfortunately.

Please check the following output:

It fails even if I force "-f mp3".

Thanks in advance for your help!
