Comment (by MasterQuestionable):

 ͏    Reading the mail list is painful...
 ͏    Horrible layout.

 ͏    https://www.mail-archive.com/search?l=ffmpeg-
 user at ffmpeg.org&q=from:%22Mark+Filipak%22&o=newest

 ͏    If every post is viewed in alike poorly sliced segments... No wonder
 the parse failure.
