Subject: extractor: youtube: Set extension of AAC audio formats to m4a.
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=16f36a6fc92d6ab89293e45de65475455fbc1b47;p=youtube-dl

extractor: youtube: Set extension of AAC audio formats to m4a.

This, in particular, eases downloading both audio and videos in DASH formats
before muxing them, which alleviates the problem that I exposed on issue

Furthermore, one may argue that this is, indeed, the case for correctness's
sake.
