It seems everything needed are these two patches, then you can build kernel packages and simply try it out. Please report back and have also a look at http://linux-sunxi.org/User:Rellla/Armbian
 
EDIT: Kernel package with patches and appropriate CMA settings: kernel-cma_ump-sun7i_5.06_armhf.tgz Please test and report back.

It's not that hard to build ffmpeg on Armbian, directly from official source. I will show all steps i am using and all codecs i install, if some is not needed, skip and remove it from ffmpeg ./config. First i create some temporary folder, it's named "t" in this example. Then we can get dependencies with "apt-get build-dep". As ffmpeg is present in Ubuntu repositories, we can get directly:
sudo apt-get update sudo apt-get build-dep ffmpeg But in Debian ffmpeg is not present, so we can get deps for libav:
sudo apt-get update sudo apt-get build-dep libav It's also a good idea to have ffmpeg support samba, so we can install it too:
sudo apt-get install samba samba-common attr samba-vfs-modules smbclient Get some more dependencies:
sudo apt-get install autoconf automake build-essential libass-dev libfreetype6-dev libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev We will probably need this packages too:
cd t wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz tar xzvf yasm-1.3.0.tar.gz cd yasm-1.3.0 ./configure --prefix=/usr make -j2 sudo make install cd .. tar -xjvf fribidi-0.19.7.tar.bz2 cd fribidi-0.19.7 ./configure make sudo make install cd .. http://savannah.nongnu.org/download/freetype/ wget http://download.savannah.gnu.org/releases/freetype/freetype-2.6.3.tar.bz2 tar xjvf freetype-2.6.3.tar.bz2 cd freetype-2.6.3 sh autogen.sh make setup ansi make -j2 cd .. Let's install some codecs, avoid what you don't need:
sudo curl https://yt-dl.org/downloads/2016.02.27/youtube-dl -o /usr/local/bin/youtube-dl sudo chmod a+rx /usr/local/bin/youtube-dl https://sourceforge.net/projects/lame/files/lame/ tar -xzvf lame-3.99.5.tar.gz cd lame-3.99.5 ./configure make -j2 sudo make install cd .. git clone http://git.videolan.org/git/x262.git cd x262 ./configure --prefix=/usr --enable-static --enable-shared make -j2 sudo make install sudo ldconfig cd .. git clone git://git.videolan.org/x264.git cd x264 ./configure --enable-static --enable-shared make -j2 sudo make install sudo ldconfig cd .. video4linux/libv4l2 git clone git://linuxtv.org/v4l-utils.git cd v4l-utils ./bootstrap.sh ./configure make -j2 sudo make install cd .. http://downloads.sourceforge.net/opencore-amr/fdk-aac-0.1.4.tar.gz tar xzvf fdk-aac-0.1.4.tar.gz cd fdk-aac-0.1.4 ./configure --prefix=/usr --disable-static make -j2 sudo make install cd .. wget http://downloads.xiph.org/releases/opus/opus-1.1.tar.gz tar xzvf opus-1.1.tar.gz cd opus-1.1 ./configure make -j2 sudo make install cd .. wget http://storage.googleapis.com/downloads.webmproject.org/releases/webm/libvpx-1.5.0.tar.bz2 tar xjvf libvpx-1.5.0.tar.bz2 cd libvpx-1.5.0 ./configure --prefix=/usr --disable-examples --disable-unit-tests make -j2 sudo make install cd .. sudo apt-get install flac git clone https://github.com/libass/libass.git cd libass ./autogen.sh ./configure --prefix=/usr make -j2 sudo make install cd .. https://www.xiph.org/downloads/ wget http://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.xz tar xJvf libogg-1.3.2.tar.xz cd libogg-1.3.2 ./configure make -j2 sudo make install cd .. wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.5.tar.xz tar xJvf libvorbis-1.3.5.tar.xz cd libvorbis-1.3.5 ./configure make -j2 sudo make install cd .. If you need x265 (as H3 support HEVC/H265) this is a tricky one and took me some time to deal with, because of a bug, so it need special attention. We need shared libraries but we will get error during make. So first some dependencies:
sudo apt-get install mercurial cmake cmake-curses-gui build-essential hg clone https://bitbucket.org/multicoreware/x265 We have to modify one file, so shared version can be build. Open the following file:
nano /t/x265/source/common/primitives.cpp
and locate this lines:
- #if ENABLE_ASSEMBLY && X265_ARCH_ARM == 0 void PFX(cpu_neon_test)(void) {} int PFX(cpu_fast_neon_mrc_test)(void) { return 0; } - #endif } #endif Remove the two lines with "-" in front and save (ctrl+o, ctrl+x). Now we can build what we need:
cd x265/build/linux ./make-Makefiles.bash #> c > g make -j2 sudo make install sudo ldconfig cd ~/t As we have all packages and codecs we need, we can build ffmpeg:
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 tar xjvf ffmpeg-snapshot.tar.bz2 cd ffmpeg ./configure --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libpulse --enable-libv4l2 --enable-libx264 --enable-libx265 make -j2 sudo make install This will take a while, but i think it worth.

The only important thing about kernel is this parameter:
CONFIG_CMA=y # CONFIG_CMA_DEBUG is not set # # Default contiguous memory area size: # CONFIG_CMA_SIZE_MBYTES=192 CONFIG_CMA_SIZE_SEL_MBYTES=y # CONFIG_CMA_SIZE_SEL_PERCENTAGE is not set # CONFIG_CMA_SIZE_SEL_MIN is not set # CONFIG_CMA_SIZE_SEL_MAX is not set CONFIG_CMA_ALIGNMENT=8 CONFIG_CMA_AREAS=7 I compiled amrbian 3.4 kernel with it and it work stable. Even the zero-copy double buffering start working with the help of this and now 1080p video acceleration is no problem. But this guy have some very modded system and it's difficult to install his versions of libraries. His UMP version is not working in my system, but i suspect i had to install fbturbo for X11 and not for framebuffer. And his libvdpau-sunxi require to remove some parameters before compilation, because of something about Valgrind i completely missunderstand. And there were many other thing i manage to solve, but those two give up me.

Hm, i really have to open this topic to find solution to my first question a minutes later. I don't know why but i have to reboot halted system during install and run - "dpkg --configure -a" . The process resumes and finish with the following errors:
but Gnome loads successfully after reboot. Of course i have to add another user instead of root to be able to login and the old problem - "the screen goes off and will not restart until reboot" remain, but it something for now.
 
So only the thing with "fb0_framebuffer_num=3" bother me for now.
