  • FFMPEG unwanted rotation

    5 mars 2015, par Ben

    When I add a watermark image with a landscape orientation to a video that has a portrait orientation the video automatically rotates to landscape. How do I prevent this ? Also, the audio file isn’t being merged into the output. How can I include the audio.mp3 to be the sole audio track ?

    *_at codecs only need the AudioToolbox framework, which is now checked
    like the other Apple frameworks.

  • ffmpef cannot open a simple microsoft wav file exported with Audacity

    23 juillet 2013, par sebpiq

    I have exported a sound file to microsoft wav using Audacity.
    I am trying to open this file with ffmpeg :

    ffmpeg -i steps-stereo-16b-44khz.wav /tmp/test.ogg

    and here's the ouput I get :

    steps-stereo-16b-44khz.wav: could not find codec parameters

    If I export the same file to .ogg or .aiff, no problem, the following works fine :

    ffmpeg -i steps-stereo-16b-44khz.aiff /tmp/test.ogg

    Any idea what could be wrong ?

    A link to my wav file so you can try to reproduce.

    NB my final goal is to slice the audio file. I know I can export file directly to .ogg with audacity. This is just a test case.
