hi10_codec or something like that

Done.

Is there a reason to use avc3 here?

[hubbe, 2016/04/01 00:20:58]

No, honestly I don't actually know what the difference between avc1 and avc3 is.

Changed to avc1 since you seem to prefer that...

[ddorwin, 2016/04/01 00:36:42]

It's just more common, so there is usually a reason that "avc3" is used. :)
