[FFmpeg-user] Trouble decoding ASF file from baby monitor

[matt]

This may be a weird edge case, but I have a Levana baby monitor that 
records ASF files which ffmpeg has trouble parsing.  I have tried 2.68 
and latest from git and get the same result (slightly different error 
verbiage).  Summary of error messages using latest from git, running  
on Fedora 22 x86_64:

  $ ffmpeg -y -i V_000038.ASF -vcodec copy -acodec pcm_s16le  test.avi
  ...
  Marker bit missing at 81 of 144 before time_increment_resolution
  [mpeg4 @ 0x2bfa840] framerate==0
  [mpeg4 @ 0x2bfa840] Failed to parse extradata

  Error while decoding stream #0:1: Invalid data found when processing input
  (repeats 21x)
  Conversion failed!

Here is the full ffmpeg output:

Here is my sample ASF file:

I have tried a few of ffmpeg's bug switches with no success.

FWIW, VLC (windows) will play the ASF with video but no audio.  MPC+HC 
doesn't play anything.  The baby monitor itself plays back the files 
fine, with video and audio.

Thanks in advance for any insight!
