  At least one output file must be specified

  I have used so many player : Audacity, VLC, WMP. But it’s sound gibberish.
  My case is very similar to

  Converting a call center recording to something useful

  in this link, he can fix by using Goldwave for converting file. I also tried Goldwave too but still didn’t work.

  So, Do I have to config more with Goldwave or any solution at least I want to listen to it

  I use MacOs but don’t mind if have to use window for open it.

  Ps. can listen sample audio in the link (my recoding is the same as the sample in this link)

• Corrupt playback of .flv when using JW Player

  21 mai 2012, par Adam Ingmansson

  This question is also asked on Audio-Video Production

  I have some files that when played in jwplayer the playback is corrupt.
  The files are encoded to h.264 using FFMpeg and there is other files encoded in the same way that works.

  At the moment we only use the flash version of the player.

  The corrupt playback looks like this :

  http://adam.ingmansson.com/public/jwplayer-corrupt-video.png

  This problem started showing up after we did an upgrade to FFMpeg, so I haven't ruled out that it could be an encoding error.

  the command used to run FFMpeg is :

  ffmpeg 
  
      -i /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.mov 
  
      -vcodec libx264 
  
      -preset ultrafast 
  
      -profile baseline 
  
      -acodec libfaac 
  
      -ab 96k 
  
      -crf 19 
  
      -vf movie="/home/adam/logo.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:main_h-overlay_h-10 [out]" 
  
      -y /home/ftp/1c8f08b7d0d9e7fa4b24066156ad50bc981497a0.flv

  I am in no way an expert in FFMpeg commandline, so feel free to point out any mistakes made.

• failed to run ffmpeg player on android

  14 juin 2014, par Hogun

  I get source from AndroidFFmpeg.
  and I succeeded to build FFmpegLibrary project and FFmpegExample.
  When I installed a app on G2 phone, ran the app well.
  but when I installed it on Galaxy S3, the app is killed by failed ffmpeg-neon.so load.
  

  I have environments blow,

  • Ubuntu 12.04 LTS 64bit
  • Android NDK r9d
  • Android Toolchain 4.6
  • FFmpeg 2.2
