media players not playing files over smb, is ffmpeg compiled without networking support?

[Dantes]

 

I am unable to play files over SMB, but I can't seem to figure out what the problem is exactly. From what I can tell it *seems* ffmpeg is compiled without networking support, at least this is what smplayer was complaining about:

 

[ffmpeg] Protocol not found. Make sure ffmpeg/Libav is compiled with networking support.
Failed to open smb://192.168.1.1/transmission/myfile.mkv.
Exiting... (Errors when loading file)

 

But when I look at the ffmpeg switches it was compiled with:

 

 --enable-libsmbclient

 

and seems to be present.

 

Now I'm a complete linux n00b, does anyone have an idea ?

I think I found the problem

 

So I compared logs from a working x86-64 system with the R6C aarch64 and as you can see mpv is compiled without --enable-libsmbclient

 

$ grep Configuration aarch64_mpv.log			      |	$ grep Configuration x86-64_mpv.log
[cplayer]							[cplayer]
Configuration:							Configuration:
./waf								./waf
configure							configure
--prefix=/usr							--prefix=/usr
--libdir=/usr/lib/aarch64-linux-gnu			      |	--libdir=/usr/lib/x86_64-linux-gnu
--confdir=/etc/mpv						--confdir=/etc/mpv
--zshdir=/usr/share/zsh/vendor-completions			--zshdir=/usr/share/zsh/vendor-completions
--enable-cdda							--enable-cdda
--enable-dvdnav							--enable-dvdnav
--enable-libmpv-shared						--enable-libmpv-shared
							      >	--enable-libsmbclient
--enable-sdl2							--enable-sdl2
							      >	--enable-sndio
--disable-build-date						--disable-build-date
--enable-dvbin							--enable-dvbin
$ 								$ 

 

Just to be clear: celluloid depends on mpv which depends on ffmpeg

 

On x86-64 (Ubuntu 22.04 LTS)  where it works:

* ffmpeg (4.2.7) is compiled without --enable-libsmbclient

* mpv (0.32.0) with --enable-libsmbclient

 

On aarch64 (Armbian/Ubuntu 22.04 LTS)  where it does not:

* ffmpeg (4.4.2) is compiled with --enable-libsmbclient

* mpv (0.34.1) without --enable-libsmbclient

 

I hereby humbly request someone with more skills to verify my findings and hopefully we can all enjoy playing files over smb:// in the future

Actually, first you should build it yourself from sources, using the desired command line arguments, which you seem to have sussed out.  At a minimum this would confirm the solution to the problem is what you suspect it is.

The next step (and this is without looking into it any further, and speaking generally, etc.) is understanding that most of userspace programs (including mpv) would be coming (unmodified) from upstream Debian.  If that's true (in this case, with mpv) you should contact the Debian maintainer for aarch64 build of mpv and ask them why that option is not enabled.  Or perhaps, inquire first on the relevant mailing list.

 

In any case, please do report back your findings.  Good luck!

Tried to compile it, but apparently my skills suck in this department. I'm ending up with errors every time. So this is best suited for someone who actually knows what he's doing.

 

What I did:

 

git clone https://github.com/mpv-player/mpv sudo apt install \     libsmbclient-dev \     meson \     cmake \     pkg-config \     libshaderc-dev \     autogen \     libunwind-dev \     libplacebo-dev \     autoconf \     automake \     libtool \     libfreetype-dev \     libfribidi-dev \     libharfbuzz-dev \     libfontconfig-dev cd mpv ./rebuild -j4

Tried building and install ffmpeg from source (with smb enabled)? Seems like mpv is depending on ffmpeg and its smb support.

Yay! I have it working

 

But I'm not an expert in compiling so ymmv

Feel free to comment or point out any mistakes

 

# when libshaderc-dev is installed the build succeeds, but has a run-time failure

sudo apt remove \
  libshaderc-dev

 

# install compiling tools

sudo apt install \

# install development libraries

sudo apt install \

touch -r mpv/build/mpv /tmp/mpv

 

# test mpv

/tmp/mpv smb://myserver/myshare/myfile.mkv

 

Yay!
