• OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error

  28 septembre 2016, par user2262504

  I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.

  It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec ’libx264’" error.

  Anyone has ideas to solve this problem ?

  More specifically :

  1. anyone knows where and how OpenCV invoke ffmpeg API ?
  2. how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?
  3. will changes of default in ffmpeg be carried to libx264 ?

  Errors :

  1. Uising CV_FOURCC('H', '2', '6', '4')
  
  [libx264 @ 0x255de40] broken ffmpeg default settings detected
  
  [libx264 @ 0x255de40] use an encoding preset (e.g. -vpre medium)

  [libx264 @ 0x255de40] profile is optional; x264 defaults to high
  
  Could not open codec 'libx264': Unspecified error
  
  
  
  2. Using FOURCC = -1 to invoke user customized codec

• drawbox don't work on remote server and works on local

  5 décembre 2015, par efpies

  I’ve got a completely weird problem.

  I need to draw the text over the filled rectangle. The problem is that the command line command that work on my local machine don’t work on the server ! To be precise, only drawbox command don’t work.

  Here’s the command.

  ffmpeg -i shake.mp4 -vf "scale=300:150,setsar=1/1,drawbox=w=300: h=16: x=0: y=134: color=0x1a5757: t=1000000,drawtext=x=5: y=136: fontfile=Arial.ttf: text='fdsf': fontcolor=0xd44e4e"  -c:v h264 -preset medium -b:v 256k  -f mp4 shake_conv.mp4

  Clarification

  It seems, that my question is unclear. Ok, here’s clarification.

  I need to draw the text over the filled rectangle.

  It means, that, at first, I have a video. Then I would like to draw a bar at the [0 ; 134] with width 300px and height 16px, painted with #1A5757 color. And over that bar should be placed a text.

  The problem is that the command line command that work on my local machine don’t work on the server !

  It means that I have 2 environments : local machine (my Mac OS X 10.9.2 with ffmpeg 2.0.2 installed) and the server (Debian 7 with ffmpeg 1.0.8 installed. Quite old, dunno, but no errors were in this case ; can’t find any info about version dependency).

  The last part,

  the command line command that work on my local machine don’t work on the server

  To be precise, only drawbox command don’t work.

  means that the same command above draws the bar I need in my local environment but don’t draw it on the server side. The text is drawed correctly in both cases. One more time : the text is drawed, the bar isn’t drawed. That’s my problem. I need a bar over the video. And there aren’t any bars when I execute this command on server.

  Now, I hope, this is quite clear.

  Here’s the output.

• How to set CONFIG_PATH in Heroku buildpack

  3 avril 2015, par johnklawlor

  Before I elaborate on the problem, I should let you know that I’ve successfully installed ffmpegthumbnailer on heroku’s bash (heroku run bash).

  I’m trying to build ffmpegthumbnailer using a custom Heroku buildpack I’ve written, but when I run ./configure && make install in the bin/compile buildpack file, ffmpegthumbnailer tells me that it can’t find the ffmpeg libs (util, format, codec, scale) and suggest that I set the PKG_CONFIG_PATH. So I set the PKG_CONFIG_PATH and it still can’t seem to find the libraries.

  I’ve tried setting the PKG_CONFIG_PATH every which way. echo export, export, directly set it via PKG_CONFIG_PATH=/app... I’ve always set it inline with the .configure command. I even set PKG_CONFIG_PATH as a heroku config var, and tried to acces it via the ENV_DIR variable that’s passed into the buildpack as the third parameter, but I soon realized that I was simply setting a variable PKG_CONFIG_PATH to the contents of the file called PKG_CONFIG_PATH, i.e. I was setting PKG_CONFIG_PATH=/app/vendor..., which I’ve already done !! None of these have worked. Also, as you can see in the compile file and the log, echo $PKG_CONFIG_PATH prints the correct path.

  What more debugging can i do ? What is going on ?

  Below is my bin/compile buildpack file, and the log after I deploy my app to heroku.

  #!/bin/sh
  
  
  
  indent() {
  
    sed -u 's/^/       /'
  
  }
  
  
  
  echo "-----> Install ffmpeg-thumbnailer"
  
  BUILD_DIR=$1
  
  VENDOR_DIR="vendor"
  
  DOWNLOAD_URL="https://ffmpegthumbnailer.googlecode.com/files/ffmpegthumbnailer-2.0.8.tar.gz"
  
  
  
  echo "DOWNLOAD_URL = " $DOWNLOAD_URL | indent
  
  
  
  cd $BUILD_DIR
  
  mkdir -p $VENDOR_DIR
  
  cd $VENDOR_DIR
  
  curl -L --silent $DOWNLOAD_URL | tar xz
  
  cd ffmpegthumbnailer-2.0.8/
  
  export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:/app/vendor/ffmpeg/lib/pkgconfig/"
  
  echo $PKG_CONFIG_PATH
  
  ./configure --prefix /app/vendor/ffmpegthumbnailer && make install
  
  
  
  echo "exporting PATH and LIBRARY_PATH" | indent
  
  PROFILE_PATH="$BUILD_DIR/.profile.d/ffmpeg-thumbnailer.sh"
  
  mkdir -p $(dirname $PROFILE_PATH)
  
  echo 'export PATH="$PATH:vendor/ffmpeg-thumbnailer/bin"' >> $PROFILE_PATH
  
  echo 'export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:vendor/ffmpeg-thumbnailer/lib"' >> $PROFILE_PATH

  Consider adjusting the PKG_CONFIG_PATH environment variable if you
  
  installed software in a non-standard prefix.
  
  
  
  Alternatively, you may set the environment variables FFMPEG_CFLAGS
  
  and FFMPEG_LIBS to avoid the need to call pkg-config.
  
  See the pkg-config man page for more details.
