• How to debug missing shared library (libffmpeg.so) while running Electron App (LBRY-Desktop) on FreeBSD Linuxulator ?

  13 septembre 2021, par xliiv

  I'm working on running an Electron Linux App on FreeBSD, namly
lbry-desktop.

  


  I did this

  


  


  1. download https://github.com/mrclksr/linux-browser-installer

     


  


  2. run from FreeBSD

     


     sudo ./linux-browser-installer chroot create
sudo chroot /compat/ubuntu/ /bin/bash


     


  


  3. run from chroot/ubuntu

     


     apt install --yes wget
cd /root
wget https://github.com/lbryio/lbry-desktop/releases/download/v0.51.2/LBRY_0.51.2.deb
apt install --yes ./LBRY_0.51.2.deb
rm /var/lib/dpkg/info/libfprint-2-2\:amd64.postinst
apt install --yes ./LBRY_0.51.2.deb


     


  


  4. back to FreeBSD

     


     > /compat/ubuntu/opt/LBRY/lbry


     


  


  


  I'm getting this

  


  /compat/ubuntu/opt/LBRY/lbry: error while loading shared libraries: libffmpeg.so: cannot open shared object file: No such file or directory
fish: Job 1, '/compat/ubuntu/opt/LBRY/lbry' terminated by signal SIGTRAP (Trace or breakpoint trap)


  


  I did some debugging, but can't get it thru.

  


  My conclusion is, it should work, since

  


  

  1. ffmpeg.so is present

> strings /compat/ubuntu/opt/LBRY/lbry|rg libffmpeg\.so
libffmpeg.so


     


  


  


  Also, from chroot

  


  root@alef14:~# ldd /opt/LBRY/lbry |grep ffmpeg
        libffmpeg.so => /opt/LBRY/libffmpeg.so (0x0000000808e00000)


  


  So I'm missing something, but can't find it.

  


  How can I debug/solve it ?

  


  Running the program from /compat/ubuntu/opt/LBRY/ dir, doesn't work as well.

• FFMPEG Error -1414092869 : Immediate exit requested

  8 juillet 2019, par Manity

  Hello i am using ffmpeg to play 4 videos at the same time.
  I am using a wpf/c# .net 4.7.2 wrapper for ffmpeg to do this.

  Occasionally get this error message, and the application just shuts down.
  there are no errors or exceptions thrown other than this one logged.

  Error -1414092869 : Immediate exit requested

  I have searched for a meaning to this error but can find nothing other than a vague reference to an android video player which does not provide me with any information at all.

  Can anyone shed any light at all, anything at all on the meaning of and cause of this above error and how it might be resolved ?.
