• FFmpeg in a bash script ( quotes )

  20 mars 2015, par Guillaume Villena

  I’m working on a script that open a text file with some ffmpeg commands. ( about 10 command generated from an other project ) Each command are working when i copy paste than into the terminal manually, but when the script run, simple commands work but I am stuck on a " No such filter : ..." error.

  Here is my command : -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -i 6.mp4 -filter_complex '[0:0][0:1][1:0][1:1][2:0][2:1][3:0][3:1][4:0][4:1][5:0][5:1]concat=n=6:v=1:a=1:unsafe=1 [v] [a]' -map '[v]' -map '[a]' -aspect 16:9 -s 1280x720 -c:v mpeg4 -c:a libmp3lame -y track_0.mp4

  I think all the problem is in the " ’ " i try to escape them with " \’ " but ffmpeg is telling me No such filter: '''

  Here is my script assuming that the variable ARGS is set dynamically ( for the example I have set it manually ) :

  #!/bin/bash
  
  ARGS="-i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -i 6.mp4 -filter_complex '[0:0][0:1][1:0][1:1][2:0][2:1][3:0][3:1][4:0][4:1][5:0][5:1]concat=n=6:v=1:a=1:unsafe=1 [v] [a]' -map '[v]' -map '[a]' -aspect 16:9 -s 1280x720 -c:v mpeg4 -c:a libmp3lame -y track_0.mp4"
  
  ffmpeg ${ARGS}

  Can you help me ?

• Powershell Job Memory Consumption Issue

  14 juillet 2016, par Matt Wall

  I’ve been struggling with this for a week now and have exhausted all the methods and options I have found online. I am hoping someone here will be able to help me out with this.

  I am using powershell to start 8 jobs, each job running FFmpeg to stream a 7 minute file to a remote RTMP server. This is pulling from a file on the disk and each job uses a different file. The command is in a do while loop so that it is constantly restreaming.

  This is causing the shell I launched the jobs from to accumulate a massive amount of memory, consuming all that it can. In 24 hours it consumed 30 of the 32 GB of my server.

  Here is my launch code, any help would be appreciated.

  start-job -Name v6 -scriptblock {
  
  do { $d = $true; $f = Invoke-Expression -Command "ffmpeg -re -i `"C:\Shares\Matthew\180p_3000k.mp4`" -vcodec copy -acodec copy -f flv -y rtmp://<ip>/<appname>/<streamname>"; $f = $null }
  
  while ($d = $true)
  
  </streamname></appname></ip>

  }

  I’ve tried to receive the jobs and pipe it to out-null, I’ve tried setting $f to $null before starting the do while loop, and some other things I found online but to no avail. Thanks everyone for your time !

• Android transplant FFmpeg, call libffmpeg.so function appears ffmpeg.c : 8 : error : undefined reference to 'avcodec_version'

  24 avril 2015, par user4827738

  I need to use FFmpeg on Android, I use the FFmpeg compiled [ffmpeg for
  android][1] got libffmpeg.so, I will put the NDK libffmpeg.so
  platforms\android-8\arch-arm\usr\lib and several in the same
  directory, the script file on the
  platforms\android-8\arch-arm\usr\include directory, and then
  reference the way I wrote on the network Android.mk file, call
  avcodec_version in C code () ; function, and then prompts ffmpeg.c : 8 :
  error : undefined reference to ’avcodec_version, please help me, I’m on
  windows7 and ubuntu 14.04 are compiled, without success，thank you very
  much !

  android.mk code content

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)

  LOCAL_MODULE    := ffmpeg
  
  LOCAL_MODULE    := hello-ffmpeg
  
  LOCAL_SRC_FILES := ffmpeg.c
