OpenH264 should work on RHEL, unless the download was blocked.
Component: Audio/Video: Playback → WebRTC: Audio/Video

What's the progress now?
Most likely they disabled OpenH264 and/or GMP by default in the "official" RH build

Check Tools->AddOns -> Plugins.  I'd bet Open H264 isn't listed as installed.

If it is installed, please re-capture about:webrtc - there's a button to save it.  "Save Page As" doesn't necessarily produce something useful - the copy here doesn't tell me anything useful.

I check the addons, seems already installed h264 in FF

yanfzhen - please capture another about:webrtc snapshot (preferably using the Save button, not Save Page As).  I need the SDP info.

What version of firefox is it?

There's not a lot to go on here. There's no SDP on about:webrtc, which probably just means that the JS that removes VP8 left no codecs in the m=video section, making it invalid.
Can you try setting NSPR_LOG_MODULES=signaling:5,GMP:5 and NSPR_LOG_FILE=/tmp/nspr.log and try again?  If the plugin is installed, that should work... Unless: while the plugin may get installed, RedHat in their "official" builds might have blocked it (deliberately or accidentally).  Please try using a RH build, and using a Linux build from mozilla.org.

I presume your report was using the default RH build they provide.  Also attach the data from about:support and about:buildconfig
