see comment in openh264_unittests; I don't understand why this is part of
content_unittests and not a separate binary?

[hbos_chromium, 2015/11/19 13:00:43]

There's overhead in creating new test binaries, I've been told that you probably
don't want to do that for a single test class and might get pushback. Also, we
only want the unittests to be included if you build with use_openh264, meaning
producing and for the trybots running the binary would be conditional or it
would have to produce a binary that doesn't have any tests if !use_openh264.

I created and landed a CL that created a new binary specifically for openh264
unittests but we reverted it in favor of content_unittests. I'll take a look at
media_unittests as an alternative.
