SIXEL Integration

Step 0. Edit .Xresources

$ cat $HOME/.Xresources
XTerm*decTerminalID: vt340
XTerm*sixelScrolling: true
XTerm*regisScreenSize: 1920x1080
XTerm*numColorRegisters: 256

$ xrdb $HOME/.Xresources  # reload

Step 1. Build xterm with --enable-sixel-graphics option

$ wget ftp://invisible-island.net/xterm/xterm.tar.gz
$ tar xvzf xterm.tar.gz
$ cd xterm-*
$ ./configure --enable-sixel-graphics
$ make
$ ./xterm  # launch

Step 2. Build FFmpeg-SIXEL with libsixel and libquvi (for network streaming)

$ git clone https://github.com/saitoha/libsixel
$ cd libsixel
$ ./configure && make install
$ cd ..
$ git clone https://github.com/saitoha/FFmpeg-SIXEL
$ cd FFmpeg-SIXEL
$ ./configure --enable-libquvi --enable-libsixel
$ make install
$ ffmpeg -i 'https://www.youtube.com/watch?v=ixaMZPPmVG0' -f sixel -pix_fmt rgb24 -s 480x270 -
