    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • 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 :

  • 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 ?

  • 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.
