And H.264 works even though the performance seems to have taken a hit. Getting video in both directions, owr -> FF.

Let's repurpose this ticket then for the libvpx crash, also relevant part from IRC log:

<slomo> yeah, videoconvert is going to be slow because we don't have orc working properly on ios
<slomo> https://github.com/EricssonResearch/openwebrtc-gst-plugins/issues/26
<slomo> i think we should look into upgrading libvpx to something newer before further investigating that crash. our version and the latest upstream version are ancient
<slomo> nirbheek: did you file a bug against libvpx to ask for a new release?
<slomo> the code where it crashes is now in a completely different file
<M-stalund> perhaps we could use videoconvert for Cerbero temporarily?
<slomo> you will probably need it also when using newer gstreamer git snapshots with the build scripts
<slomo> let's check with superdump later what he thinks should be the way forward here. i would move to videoconvert and then "just" make it work fast on ios (oh, orc also does not have arm64 support yet... but that also shouldn't be too difficult)
<slomo> superdump, nirbheek: https://github.com/webmproject/libvpx/commit/33df6d1fc1d268b4901b74b4141f83594266f041 this might be the real fix for the -O1 workaround btw
<slomo> and https://github.com/webmproject/libvpx/commit/feaf766bd04fc2d0a75d322f41785a1ecf076b30 will make it even work fast on arm64 afaiu, and probably solves other problems on the way

New version of libvpx can be tested from here: https://github.com/ford-prefect/cerbero/commits/openwebrtc

I've updated the libvpx work there, and tested a FF (Mac OS) -> Bowser call
with this. The video turns up without artifacts on both sides. There are
other issues that we need to investigate, primarily related to the
framerate and latency, but the libvpx issue should be fixed once we merge
my patches.

For some reason I could not build and was therefore not able to verify. But if @ford-prefect says it's working then I'm ok with merging this.
