• error : av_interleaved_write_frame() : Unknown error

  12 avril 2014, par John Qualis

  I am new to ffmpeg. I am trying to stream my webcam using ffmpeg (x264 encoding) on a windows machine to ffserver on a linux server and restream it. I am getting the following error : av_interleaved_write_frame() : Unknown error
  I checked about it on the net and came across mails which said it could be related to version mismatch between ffmpeg and ffserver. I made sure that all libraries that are used by ffmpeg and ffserver have the same version. I am still getting this error. Appreciate any help in solving this issue.

  I am using the following command :

   .\ffmpeg.exe -f dshow -i video="Webcam C170":audio="Microphone (3- Webcam C170)" -an -g 94 -vcodec libx264 -b:v 512k -r 30 -f flv http://AA.BB.CC.DD:8090/feed1.ffm

  I get the followoing errors -

• Unknown encoder 'libx264' - Heroku Rails App

  11 février 2014, par scientiffic

  In my Rails app, I installed ffmpeg on Heroku in order to transcode uploaded video files.

  This worked fine until I added exiftool functionality (as outlined in this stackoverflow post) and I started getting the error 'Unknown encoder libx264' when I try to transcode videos (ONLY when I try uploading video through Heroku ; I don't get any errors when I upload videos locally). The full error message from my heroku logs is below :

  Running transcoding...
  
  ffmpeg -y -i /app/public/uploads/tmp/1392153416-9-9551/portrait.mp4 -vcodec libx264 -acodec libfaac -s 640x360  -vf transpose=1 -aspect 0.5625 /app/public/uploads/tmp/1392153416-9-9551/tmpfile.mp4
  
  
  
  Failed encoding...
  
  ffmpeg -y -i /app/public/uploads/tmp/1392153416-9-9551/portrait.mp4 -vcodec libx264 -acodec libfaac -s 640x360  -vf transpose=1 -aspect 0.5625 /app/public/uploads/tmp/1392153416-9-9551/tmpfile.mp4
  
  
  
  Unknown encoder 'libx264'

  I don't know why I'm getting this error because I installed ffmpeg with the —enable-libx264 option (my full installation instructions are here), and when I run 'which x264' in the heroku bash, it does return the correct path.

  The strangest part is that I'm testing everything on my test server right now, and my deployed app on my main server is able to run the transcoding with no problems using libx264. The only difference between my main server and test server is the addition of exiftool.

  Does anyone have any idea what's going in here ??
