Comment (by peterbennett):

 I tested this with the ffmpeg executable and I cannot reproduce it that
 way. I traced through ffmpeg and it does call the sws_scale in a slightly
 different way. When running the command line through ffmpeg there is the
 following message
  [swscaler @ 0xad1c0] No accelerated colorspace conversion found from
 yuv420p to bgra.
 The command line I used is
  ffmpeg -ss 2.0 -i /path/filename -frames 1 -pix_fmt bgra imagefile.bmp
 It produces an image file without failure, and seems to be the same thing
 we are trying to do.
 I do not know the cause of our error. We have a workaround and if you see
 no bug in ffmpeg here, please close the ticket.
