  • Encode & play video formats without 3rd party codec packs

    20 septembre 2013, par Jezza

    We have built a windows based software system that allows users to import their own video for viewing in the software. It works fine for AVI and WMV as we use a windows based player. For encoding or playing to work with most common video formats we have to ask our customers to download a 3rd party codec pack, such as K-Lite or Combined Community Codec Pack. Many of our customers are not allowed to do this due to IT Management rules.

    Are they are any suggestions regarding a player and encoder that can be built into our windows based software without needing 3rd party codec packs.

    I am not sure if ffmpeg, handbrake, VLC can be used for this purpose.

    Thanks. J

  • Invalid buffer size, packet size 1447 expected frame_size 460800

    24 février 2017, par Thiruvarangan Vedantham

    I am trying to display raw video being captured from a capturing device using ffplay. The following command works fine :

    ’ffplay -fs -i /dev/video1’

    However, I need to rename the capture device to ’webcam’ and have added necessary UDEV rules and then trying to play using the following command :

    ’ffplay -s cif -pix_fmt yuv420p -f rawvideo /dev/webcam’

    This command gives me the following error :

    Invalid buffer size, packet size 1447 < expected frame_size 460800.
    Also tried :

    ’ffplay -fs -i /dev/web-cam’

    which gives me the following error :

    Invalid data found when processing input. Please help.

    Thanks in advance.
