  • Make a FFmpeg thumbnail ?

    16 décembre 2014, par user1826795

    I’m kind of new with FFmpeg but as a project to learn some mysql databasing I’m trying to create a video upload site.

    When I try to make a thumbnail with this code :

    shell_exec("/usr/local/bin/ffmpeg -i anim.flv -an -ss 00:00:03 -an -r 1 -vframes 1 -y test.jpg") ;

    nothing happens, no image appear in the same directory as the anim.flv, is there something wrong with the code or what could the problem be ?

  • how to build ffmpeg with burn text on hls output while maintaining the aspect ratio

    26 février 2016, par Aameer

    My objective is to burn a text(watermark) at a particular time range on the outputed hls video, I also have to change just the height and maintain the aspect ratio which I am able to do but the burning in text part is not working. First the ffmpeg I used is for 14.04 ubuntu, details are here. I don’t think this build supports subtitle (docs) filter which I could have used for my purpose as described here. when i enter ffmpeg into the terminal this is the output

    but got an error

    Could not write header for output file #0 (incorrect codec parameters ?): No such file or directory

    Any help in this regard would be appreciated. I don’t have much experience with compiling , otherwise would have done with support for libass as mentioned in the documentation here
