Subject: [FFmpegPostProcessor] Default of prefer ffmpeg
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=374c761e77b09b07918f525ad74724650309015f;p=youtube-dl

[FFmpegPostProcessor] Default of prefer ffmpeg

When no `downloader` is passed to `FFmpegPostProcessor`
an exception was raised trying to get the prefer ffmpeg param.

    AttributeError: 'NoneType' object has no attribute 'params'

This fixes and defaults to `False`.
