Regression since 0a7bf34
Is this also reproducible with ffmpeg -i ... -vn out.wma ?
Are you able to provide a file to reproduce the problem?
comment:3 by , 12 years ago
This is not really regression since 0a7bf34 because that commit actually revealed how encoder is buggy.
(It probably should be marked experimental long ago...)

Using "-ar 44100" also faults.
Dropping the "-ar 48000" works.
Using "-ar 22050" works. Which makes me think that it could be related to this ticket:
https://ffmpeg.org/trac/ffmpeg/ticket/1495
... where audio output is corrupt with 48Khz and 44.1Khz, but not 22.050Khz.

The assert is triggered through the regression described in ticket #1495, I was so far unable to produce an input sample that triggers the assert without -ar 48k.
comment:7 by , 12 years ago
I could not reproduce it but i found several issues in wmaenc some may have caused this, they are fixed now.
Please retest

Still fails here with current git head:
