  • Alternative to ffmpeg for dynamically creating video thumbnails

    3 novembre 2013, par user763852

    The server hosting my website doesn't have ffmpeg and I am not allowed to install any additional extensions. Is there any other way I can make video thumbnails dynamically ? Perhaps some kind of web service, where I pass the video file and as a result I get a picture file. I'm using php, by the way.

  • .mov conversion to .mp4 using ffmpeg doesn't convert the entire video

    5 février 2013, par user504879

    I am trying to convert a mov file which I got from saving my powerpoint presentation to a movie file. However only a part of the presentation is converted not the entire one and also running qt-start doesn't make the exported mp4 to stream over rtmp. Is there something which I am missing ?

    I am attaching the output which i get when I am trying to convert the file using ffmpeg

    $ export LD_LIBRARY_PATH=/usr/local/lib; /usr/local/bin/ffmpeg -y -i /data/tmp/vialogues_prez.mov -r 20 -g 40 -acodec libfaac -ar 44100  -ab 96k -vcodec libx264 -s 640x480 -vpre medium /data/videos/vialogues_prez.mp4
