Please consider applying the fix below onto libav:
The command I tried was
avconv -loop 1 -f image2 -i
/usr/local/share/devede_ng/silence.ogg -y -target pal-dvd -acodec mp2 -s
720x576 -g 12 -b:v 2500k -b:a 224k -aspect 4:3 -t 31
.... which is produced by an application called DeVeDe NG.
The command fails as described in the ticket
Changing the bitrate of the audio codec from 224k to 128K, 64K, 32K, 16K, 8K is
absolutely innefective. The error persists.
Changing the audio codec from mp2 to mp3 circumvents the trouble.
Ways to circumvent the trouble:
1. package devede (which is the 'old' version of the application) works fine in
a similar scenario.
But package devede has other bugs and apparently is not being actively
maintained, since there's a new version of the application.
2. I can modify devede-ng (the 'new' version of the application) and build from
This way the behavior being employed by the 'old' version of the application
can be applied to this case.
