Do we need to propagate all the flags?

Sorry I can't answer this question. I just restore it to be same as before.
If anyone could confirm it's not needed here, I can help to remove it.
BTW: test shows that removing them is OK.

How did you test? Were the codec-specific flags propagated to GPU and renderer
processes? Were you able to selectively disable each codec with each flag alone
(i.e. only VP8 with kDisableWebRtcHWVP8Encoding and only H264 with
kWebRtcHWH264Encoding), while having the other HW codec working still?

[braveyao, 2016/12/20 19:09:14]

Yes VP8 and H264 can be selectively disabled with each flag.
And I don't think the codec-specific flags need to be propagated between GPU and
renderer processes. So I suppose no change here.
