Title:
  Converting ogv to asf using avconv fails - decoding failed

Status in libav package in Ubuntu:
  Incomplete

Bug description:
  When trying to convert an ogv that I have created using gtk-
  recordmydesktop to asf format I get two errors:

  [ogg @ 0x8e11240] decoding for stream 0 failed
  [...]
  [wmav2 @ 0xa125ea0] output buffer size is too small

  I was used to do it with ffmpeg the following way
  ffmpeg -i "/home/myuser/out.ogv" -vcodec wmv2 -sameq -acodec wmav2 -f asf "/home/myuser/out.ogv.asf"

  After getting the message mentioned in bug #1005536 I tried converting
  it with avconv as I am told and did not find any difference regarding
  the used commandline parameters, so I kept it quite similar (-sameq
  not supported so I assumed I can omit it):

  avconv -i "/home/myuser/out.ogv" -vcodec wmv2 -acodec wmav2 -f asf
  -err_detect buffer "/home/myuser/out.ogv.asf"
