Nightingale created from yaml won't play music

[darealshinji]

Nightingale uses gstreamer. Maybe there are some issues with the plugins and their dependencies not being tracked correctly?

[probonopd]

Please provide additional information. Which distribution and version are you using? Can you use sudo strace -eopen -f the.AppImage and check for output related to the problem?

[probonopd]

It won't even let me import a mp3? Is this even AppImage related?

[darealshinji]

The AppImage created with this (not very elegant) Recipe is able to play mp3s: https://gist.github.com/darealshinji/abcfffb658f1a801ce12a332809b084b

The gstreamer "ugly" plugins are required for mp3 playback: http://packages.ubuntu.com/trusty/gstreamer0.10-plugins-ugly

[probonopd]

Isn't gstreamer 0.10 really replaced by 1.0 since a long time? Just curious...

[darealshinji]

It looks like it isn't available anymore in yakkety, but trusty still has it including all the plugins. xenial lacks some plugins. Unfortunately Nightingale requires gstreamer 0.10.

This script creates a working AppImage for me:

app: Nightingale

ingredients:
  dist: trusty
  sources: 
    - deb http://archive.ubuntu.com/ubuntu/ trusty main universe
  ppas:
    - djcj/nightingale

script:
  - sudo apt-get install -y libglib2.0-bin
  - mv usr/lib/x86_64-linux-gnu/gstreamer-0.10/* usr/lib/nightingale/gst-plugins/
  - rm -rf usr/lib/x86_64-linux-gnu/x264-10bit/ usr/bin/nightingale
  - cat <<\EOF> usr/bin/nightingale
  - #!/bin/sh
  - cd "`dirname "$0"`"
  - export GST_PLUGIN_SCANNER="`pwd`/../lib/x86_64-linux-gnu/gstreamer0.10/gstreamer-0.10/gst-plugin-scanner"
  - "`pwd`/../lib/nightingale/nightingale" $*
  - EOF
  - chmod a+x usr/bin/nightingale

Thanks @darealshinji. Getting lots of

(gst-plugin-scanner:12987): GStreamer-WARNING **: Failed to load plugin '/tmp/.mount_WmxjL5/usr/lib/nightingale/gst-plugins/libgst*.so': libgcrypt.so.11: cannot open shared object file: No such file or directory

on the console. Possibly we need to bundle libgcrypt?

[darealshinji]

Possibly we need to bundle libgcrypt?

I've tried, but I don't know how to do that.

[probonopd]

Insert the packages like this:

ingredients:
  dist: trusty
  packages:
    - nightingale
    - libgcrypt
  sources: 
    - deb http://archive.ubuntu.com/ubuntu/ trusty main universe
  ppas:
    - djcj/nightingale

[darealshinji]

I've added the package libgcrypt11 but I still get the warnings about libgcrypt.so.11 missing.

[probonopd]

Can you verify that it ended up in the AppDir? Where?

[darealshinji]

$ find Nightingale/* -name libgcrypt.so.11*
Nightingale/Nightingale.AppDir/lib/x86_64-linux-gnu/libgcrypt.so.11
Nightingale/Nightingale.AppDir/lib/x86_64-linux-gnu/libgcrypt.so.11.8.2

Is that directory not within the AppImage's library search path?

[probonopd]

Should be, but to debug try

• running with strace -eopen -f ./AppRun and watch the output
• running with LD_DEBUG=libs ./AppRun and watch the output
• moving the lib to $APPDIR/usr/lib/ and retry

[darealshinji]

I did some checks and came to the conclusion that apparently some dependencies are loaded from the host system rather than from the AppImage.
It shows this warning: Failed to load plugin '/tmp/.mount_H8c1XW/usr/lib/x86_64-linux-gnu/gstreamer-0.10/libgstlv2.so': /usr/lib/x86_64-linux-gnu/libhogweed.so.4: undefined symbol: __gmpn_cnd_sub_n
libhogweed.so.4 is not available on Ubuntu 14.04, only libhogweed.so.2.

Here's my current script:

app: Nightingale

ingredients:
  packages:
    - nightingale
    - libcurl3-gnutls
    - libhogweed2
  dist: trusty
  sources: 
    - deb http://archive.ubuntu.com/ubuntu/ trusty main universe
  ppas:
    - djcj/nightingale

  - sudo apt-get install -y libglib2.0-bin
  - rm -rf usr/lib/x86_64-linux-gnu/x264-10bit/ usr/bin/nightingale
  - cat <<\EOF> usr/bin/nightingale
  - #!/bin/sh
  - usr="`pwd`"
  - export LD_LIBRARY_PATH="$usr/lib/nightingale/xulrunner:$LD_LIBRARY_PATH"
  - export GST_PLUGIN_PATH="$usr/lib/x86_64-linux-gnu/gstreamer-0.10:$usr/lib/nightingale/gst-plugins"

  - "$usr/lib/nightingale/nightingale-bin" $*
  - EOF
  - chmod a+x usr/bin/nightingale

libhogweed.so.4 is not available on Ubuntu 14.04, only libhogweed.so.2.

This means what, that the ppa packaging is broken?

[darealshinji]

The gstreamer plugins aren't build in my PPA. But I've fixed it. The packages libcurl3-gnutls and libhogweed2 are dependencies of the troublesome plugins, but they're not installed with the gstreamer packages.
Here's my new script:

app: Nightingale

ingredients:
  packages:
    - nightingale
    - libcurl3-gnutls
    - libhogweed2
  dist: trusty
  sources: 
    - deb http://archive.ubuntu.com/ubuntu/ trusty main universe
  ppas:
    - djcj/nightingale

script:
  - sudo apt-get install -y libglib2.0-bin
  - rm -rf usr/lib/x86_64-linux-gnu/x264-10bit/ usr/bin/nightingale
  - cat <<\EOF> usr/bin/nightingale
  - #!/bin/sh
  - usr="`pwd`"
  - export LD_LIBRARY_PATH="$usr/lib/nightingale/xulrunner:$LD_LIBRARY_PATH"
  - export GST_PLUGIN_PATH="$usr/lib/x86_64-linux-gnu/gstreamer-0.10:$usr/lib/nightingale/gst-plugins"
  - export GST_PLUGIN_SCANNER="$usr/lib/x86_64-linux-gnu/gstreamer0.10/gstreamer-0.10/gst-plugin-scanner"
  - "$usr/lib/nightingale/nightingale-bin" $*
  - EOF
  - chmod a+x usr/bin/nightingale

Now I'm also starting nightingale-bin directly instead of its wrapper script.

[darealshinji]

Should I open a pull request?

[probonopd]

Yes please. 👍
