  • How do I run the qt ffmpeg wrapper example ? (error : cannot find -lavutil)

    29 août 2013, par James

    I am using QT 4.8 on the raspberry pi trying to save a binary stream to a video file like mp4. I was able to create and save static images by converting it into a QImage, but QT does not seem to support actually saving that stream (or the series of QImages) to a video file.

    The only option I may have found is qt ffmpeg Wrapper
    https://code.google.com/p/qtffmpegwrapper/

    but the example won't run out of the box. I am having the same exact problem as this guy :

    https://code.google.com/p/qtffmpegwrapper/issues/detail?id=14&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary%20Opened%20Closed%20Modified#makechanges

    All I did was download it and try to run the included example, but no go.
    Am I supposed to download ffmpeg files prior to using this ? apt-get install ffmpeg ?

    Thanks !

  • Find out what device to use for capturing with ffmpeg ?

    14 septembre 2013, par wvxvw

    I'm trying to broadcast my screen and I cannot capture audio. There's one complication however. I don't have pulseaudio, and it simply doesn't work on my system, so installing it is out of question. Below is the command I'm trying :

    ffmpeg -f alsa -i ??? -f x11grab -s 1920x1200 -r 15 -i :0.0 \
    
    -acodec pcm_s16le -vcodec libx264 \
    
    -preset fast -pix_fmt yuv420p -s 1280x800 -threads 0 -f flv "$URL"

    Here's the list of my audio devices :

    I know that ??? should be something like hw:X,Y, but maybe it can be something else. I can't find the corresponding entry in the man page.

    As an aside, it would be great if you can suggest another audio codec. I can't find what are the options, and this particular one isn't compatible with FLV because of too high bitrate.

    PS. This is the error I'm getting :

    Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input
