Already from earlier, but we should have #include "webrtc/video_frame.h" in this
file.

[mflodman, 2015/11/25 12:15:19]

And I'd prefer to call this just 'denoiser_', since it's already implied this
code is for video.

I know you said video_denoiser_ Stefan, but WDYT?

[stefan-webrtc, 2015/11/25 12:16:52]

Sounds good to me.

[jackychen, 2015/11/25 20:29:05]

Done.

[jackychen, 2015/11/25 20:29:05]

Done.
