I would like to build mpv from source for the raspberry pi. This is turning out to be quite difficult.

Error

Setup & Procedure

OS: Raspbian Stretch 2018-06-27

Hardware: Raspberry Pi 3B/3B+

sudo apt-get update -y 
sudo apt-get upgrade -y 
sudo rpi-update

in raspi-config, go to advanced > memory split: 256

reboot now

sudo apt-get install -y gperf bison flex autoconf automake make texinfo help2man libtool libtool-bin ncurses-dev git yasm mercurial cmake cmake-curses-gui libfribidi-dev checkinstall libfontconfig1-dev libgl1-mesa-dev libgles2-mesa-dev gnutls-dev libsmbclient-dev libpulse-dev libbluray-dev libdvdread-dev libluajit-5.1-dev libjpeg-dev libv4l-dev libcdio-cdda-dev libcdio-paranoia-dev libmp3lame-dev libx264-dev 

git clone https://github.com/mpv-player/mpv-build.git
cd mpv-build

export LIBRARY_PATH=/opt/vc/lib
export PKG_CONFIG_PATH=/opt/vc/lib/pkgconfig/
export CPATH=/opt/vc/include
# export LDFLAGS="-L/opt/vc/lib"

echo "--enable-libx264
--enable-omx-rpi
--enable-libmp3lame
--enable-mmal
--enable-gpl
--enable-nonfree
--disable-v4l2-m2m" > ffmpeg_options

echo "--enable-rpi
" > mpv_options

./update
./rebuild -j4
sudo scripts/mpv-install

Things I've tried

  1. Links like this

    sudo ln -s libbrcmEGL.so libEGL.so sudo ln -s libbrcmGLESv2.so libGLESv2.so

  2. Links like this, (source)

    sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so sudo ln -fs /opt/vc/lib/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so sudo ldconfig

Neither worked, so then I rebooted and did some more searching. I found some posts saying it was an opengl problem so I tried to install new opengl packages

sudo apt-get install -y libglu1-mesa-dev freeglut3-dev mesa-common-dev

That didn't work, so I thought maybe it couldn't find packages I already had installed. I tried exporting the variables that were used in the install

export LIBRARY_PATH=/opt/vc/lib export PKG_CONFIG_PATH=/opt/vc/lib/pkgconfig/ export CPATH=/opt/vc/include

still nope.

Next I found a guide saying there needed to be an rpi-update. I had run one at the beginning, but I decided to try again.

sudo rpi-update

no luck!

Found another post that led to this

sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so.1 sudo ln -fs /opt/vc/lib/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so sudo ln -fs /opt/vc/lib/libGLESv2.so /usr/lib/arm-linux-gnueabihf/libGLESv2.so.2

After this point desperation and frustration sink in and further attempts go undocumented. Needless to say, nothing I tried worked, which leads me to post here

  • why not sudo apt install mpv? – answerSeeker Jul 14 '18 at 1:47
  • It doesn't really work for rpi. It needs FFmpeg to be installed with hardware acceleration (the mmal in title) or it's basically unusable, like 1 frame per second. – Alter Jul 14 '18 at 1:49

I have an RPi3B+ I just installed mpv and ffmpeg 3.4.1 by following this well-written tutorial:

https://www.raspberrypi.org/forums/viewtopic.php?t=199775

It worked. I suggest you follow the tutorial to the letter. If it says "reboot", then do that. Don't think "Oh not necessary yet."

Actually, I only wanted to update ffmpeg, but in the end I achieved my goal (updated ffmpeg), but I am also very impressed with the performance of mpv now that it is using the Rpi's hardware acceleration.

Hope this helps.

  • Hi and welcome. It would be better if you edited and included the process and any code, from the link, in your answer. As it stands this is a bit of a link only answer. If the link dies then your answer will not be of much use to anyone, unfortunately. – Greenonline Jul 17 '18 at 19:36
  • Awesome, this worked for me. It's unfortunate the mpv-build tools don't work directly – Alter Jul 18 '18 at 23:13

"In normal circumstances there is NEVER a need to run rpi-update as it always gets you to the leading edge firmware and kernel and because that may be a testing version it could leave your RPi unbootable". https://www.raspberrypi.org/forums/viewtopic.php?p=916911#p916911 Even the rpi-update documentation now warns "Even on Raspbian you should only use this with a good reason. This gets you the latest bleeding edge kernel/firmware."

sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel will put it back to the latest supported kernel/bootcode.

  • Thanks, I'll try this. The reason I ran rpi update is that several times it came up from other posters that it may be required for mpv compilation. Here are a few examples from a forum post 1, post 2 – Alter Jul 14 '18 at 1:58
  • Reverting did not change the error message – Alter Jul 14 '18 at 2:02
