Further information¶

Note that this error relates to using ffmpeg-git (e.g. ffmpeg compiled from master). See, for instance, this pr here: https://github.com/dmlc/decord/pull/160/files

Perhaps an idea to change the title, since the problem isn't architecture specific at all, but related to one's ffmpeg installation?
