• "Unrecognized option 'filter_complex'" error when using FFmpeg in Android

  22 juin 2016, par Gaganpreet Singh

  I am creating a watermark application using FFmpeg in Android.
  I used the following command

  ffmpeg -i /storage/emulated/0/WhatsApp/Media/WhatsApp Video/VID-20150217-WA0002.mp4 -i /storage/emulated/0/mp4parser/img001.png -filter_complex '[0:v][1:v]overlay[out]'  -map '[out]' /storage/emulated/0/WhatsApp/Media/WhatsApp Video/trimmed-038-VID-20150217-WA0002.mp4

  When I launched the app, I got this line in the log :

  Unrecognized option 'filter_complex'

  I have read this command on the FFmpeg.org site, but I don’t know why it is not working. Below is the log :

  I have also tried using filter:v.

• 2D video to VR 360° "wall of TV's" ?

  1er septembre 2020, par ƬƦƖƝƛ

  What would be involved in creating a 360° "wall of TV's" style VR video from a bunch of 2d videos ? (surrounding the viewer)

  


  Is that complexity of rendering even possible using typical software (ffmpeg ?) on an average home computer ?

  


  
  
[okay, maybe not THAT complex !]

  


• Compiling FFmpeg on OSX - "speex not found using pkg-config"

  19 septembre 2016, par n4zArh

  I recently had few problems with FFmpeg and compiling it to get library. I managed to get through all of them, however recently I found out I need to add Speex decoder (and possibly encoder) to my project. I got Speex by sources, ./configure and make;make install (later - as I had problems - I also used Brew to download Speex). I added --enable-libspeex to my configure script and every time I try to use it I get "Speex not found using pkg-config" error.

  I am sure that there’s Speex files at /usr/local/include and lib directories, I also added those two as CFLAGS and LDFLAGS, I tried building Speex with or without using --prefix (both pointing to /usr/ and /usr/local/), I tried modifying FFmpeg’s configure file (require_pkg_config with Speex call), but no matter what I try to do I fail to build it - every time with same error.

  Long story short - how to build FFmpeg with Speex decoder on OSX ? I read somewhere that libspeex-dev might be needed, but it’s available through apt-get and not Brew (unless I screwed something up).

  My build script :

  #!/bin/bash
  
  
  
  if [ "$NDK" = "" ]; then
  
      echo NDK variable not set, assuming ${HOME}/android-ndk
