Hi I have some issues with 16 kHz encoding using speex 1.1.7. when running back-2-back I get warning messages: warning: Invalid wideband mode encountered. Corrupted stream? warning: Invalid wideband mode encountered. Corrupted stream? warning: Invalid wideband mode encountered. Corrupted stream? warning: Invalid mode encountered: corrupted stream? warning: Invalid wideband mode encountered. Corrupted stream? all other combinations (8 kHz enc/dec, 16 kHz dec, 32 kHz enc/dec) works fine. this code is a modified version based on 1.1.7. do you have any good hints for where to start looking ? should I upgrade to latest svn HEAD ? thanks. /alfred
