appears to be the cause of the regression. It was later reverted
(https://webrtc.googlesource.com/src.git/+/3bb1194fff251bb63062aa1a807ee7107779f36b),
but I guess that wasn't backported to branches 65 and 66.
Forcing rtc_use_h264 to true in the build flags should do the trick.

Title:
H264 missing from WebRTC (regression)
Status in chromium-browser package in Ubuntu:
Confirmed
Bug description:
H264 is missing from WebRTC in Chromium 65.0.3325.181.
This is a regression. It worked in Chromium 64.0.3282.167.
According to the webrtc team it might be because of a missing flag [1].
Steps to reproduce:
1. Install Chromium on Ubuntu 16.04: sudo apt-get install -y chromium-browser
chromium-codecs-ffmpeg-extra
2. open a tab with chrome://webrtc-internals
3. Create a room in https://appr.tc and join the room.
3. Check the SDP offer in webrtc-internals. Select the
https://appr.tc/r/<room-id> tab and click on the createOfferOnSuccess event.
We should have H264 in the SDP offer but it's missing:
a=rtpmap:100 H264/90000
