Subject: [external:ffmpeg] In test harness, limit to 10k download size
X-Git-Url: http://git.bitcoin.ninja/index.cgi?p=youtube-dl;a=commitdiff_plain;h=6d0fe752bfeaa9a758099315f006bc15acd1ae76

[external:ffmpeg] In test harness, limit to 10k download size

Otherwise, if you screw up a playlist test by including a playlist
dictionary key, you'll be there for eons while it downloads all the
files before erroring out.
