[vdr] softdevice crash in libasound

[Nicolas Huillard <nhuillard@ghs.fr>]

Hello,

After upgrading to ffmpeg 0.4.9pre1, and updating my Debian testing 
(with came with a upgrade of libasound from 1.0.4 to 1.0.5), I have less 
crashes, and the remaining one are (as of now) all in 
/usr/lib/libasound.so.2 (see below). After such a crash, I even have to 
restart the computer because there is no more audio or video on live 
channels (recordings still show up).

Are there known bugs in libasound ? In conjonction with ffmpeg ? The 
video and audio are still a lot jerky on many channels : any ideas what 
to update ?


Starting program: /usr/bin/vdr --config=/etc/vdr --video=/home/video 
--lib=/usr/lib/vdr/plugins --shutdown=/bin/true --plugin=softdevice\
