The static FFmpeg build was downloaded from here:

comment:2 Changed 4 years ago by cehoyos

  • Component changed from FFmpeg to undetermined
  • Description modified (diff)
  • Keywords wma regression added
  • Priority changed from critical to important
  • Summary changed from Crashes with rtmp stream -> .asf/wmv to Assertion fails when encoding wmav2
  • Version changed from unspecified to git-master

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 Changed 4 years ago by richardpl

This is not really regression since 0a7bf34 because that commit actually revealed how encoder is buggy.
(It probably should be marked experimental long ago...)

comment:5 Changed 4 years ago by grolschie

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.

comment:6 Changed 4 years ago by cehoyos

  • Component changed from undetermined to avcodec
  • Reproduced by developer set
  • Status changed from new to open

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 Changed 4 years ago by michael

I could not reproduce it but i found several issues in wmaenc some may have caused this, they are fixed now.
Please retest

comment:8 Changed 4 years ago by cehoyos

Still fails here with current git head:
