• How to fix "FFmpeg command cannot work when multiple mp3 file to process into one" on server side

  9 février 2019, par Harshil Dholakiya

  I am using FFmpeg in my php yii2 project. FFmpeg working fine in my project but one major problem is execute FFmpeg command with multiple input file. When i try to use single file to process in ffmpeg command then it works. so, how can i fix this problem ? I am using hostGator shared plan for my project. Please, help if is there any process limit or file open limit on server that i don’t know.

  I have tried using this command in php exec() :

  ffmpeg -y -i /uploads/ac/10122018-09351115-a94rlvlawvikskb4vdrca.mp3 -i /uploads/ac/09012019-035928988-assknyrk8oujccwevir7.mp3 -f lavfi -i anullsrc -filter_complex "[2]atrim=duration=3[g0];[2]atrim=duration=1[g1];[2]atrim=duration=5[g2];[g0][0][g1][1][g2]concat=n=5:v=0:a=1" /uploads/jm/concat.mp3 2>&1

  Above command works local side but not working on server side.

  output on server side with error code 1:
  
  Press [q] to stop, [?] for help
  
  pthread_create failed: Resource temporarily unavailable. Try to increase `ulimit -v` or decrease `ulimit -s`.

• Linking FFMPEG library in Ubuntu error : undefined reference [on hold]

  12 mai 2016, par mofed8461

  I’m using CMAKE in my project, i usually compile FFMPEG using

  ./configure

  make and make install

  then i copy libraries to my project compile my project as i do usually in MAC OS X, but its generate "undefined reference"
  My compile options in CMAKE :

  FIND_LIBRARY(LIB_XV libXv.a)
  
  FIND_LIBRARY(LIB_X11 libX11.a)
  
  FIND_LIBRARY(LIB_XEXT libXext.a)
  
  FIND_LIBRARY(LIB_VA libva.so)
  
  FIND_LIBRARY(LIB_VAX11 libva-x11.so)
  
  FIND_LIBRARY(LIB_XCB libxcb.a)
  
  FIND_LIBRARY(LIB_XAU libXau.a)  
  
  FIND_LIBRARY(LIB_XCBSHM libxcb-shm.a)
  
  FIND_LIBRARY(LIB_XCBXFIXES libxcb-xfixes.a)
  
  FIND_LIBRARY(LIB_XCBRENDER libxcb-render.a)
  
  FIND_LIBRARY(LIB_XCBSHAPE libxcb-shape.a)
  
  FIND_LIBRARY(LIB_ASOUND libasound.so)
  
  FIND_LIBRARY(LIB_SDL libSDL.a)
  
  FIND_LIBRARY(LIB_M libm.so)
  
  FIND_LIBRARY(LIB_LZMA liblzma.a)
  
  FIND_LIBRARY(LIB_Z libz.a)
  
  FIND_LIBRARY(LIB_BZ2 libbz2.a)
  
  FIND_LIBRARY(LIB_XDMCP libXdmcp.so)
  
  FIND_LIBRARY(LIB_PTHREAD libpthread.a)

  then i link my library using target_link_libraries as usual

  Here is CMAKE file, generated make file, output and error of make VERBOSE=1

  What libraries do i need to link to make it work ? is the above libraries enough ?

• A third-party library (FFMpeg) is spamming output

  14 janvier 2015, par Maciej Stachowski

  I’m using otherwise brilliant AForge library in my console project to encode video. When I run the project from under Visual Studio (both in Debug and Release modes), it works fine. However, running it as a stand-alone application produces the following :

  

  (the prompt being in the third line is an artifact of me using Console.SetCursorPosition extensively).

  As far as I can tell, there’s no way to configure ffmpeg from under AForge to avoid this error, and the resulting video files are fine anyway, so I’d like to simply shut it up.

  It seems, however, that even setting

  Console.SetError(StreamWriter.Null);
  
  Console.SetOut(StreamWriter.Null);

  does nothing - my app is trying to write something in the first two lines (another oddity), but gets spammed out by ffmpeg output.

  Can I do anything about it ?
