Because of the strange bugs I get in Jami, I tried to be as close as
possible to the official Jami package. They use this particular commit
and if I remember correctly, applying the patches failed without it.

The patches add:

-Hardware acceleration to use GPU instead CPU to encode/decode video
whenever possible
-All codecs available (but nor really important, it will be ok with
h264 + vp8)
-REMB feedback (./ffmpeg/rtp_ext_abs_send_time.patch) to automatically
adapt the bitrate and avoid dirty video.

I tried asking Jami devs how important are these flags, but never got
answer. I can ask again, but for now I must check one more thing
related to the strange bug I get.
