  • To get OpenCV VideoWriter work across platforms consistently for MP4 container with H264 encoding

    28 mars 2019, par Moh

    I am trying to get OpenCV VideoWriter work across platform consistently for MP4 container with H246 encoding.

    Target platforms in order of importance - Ubuntu, Raspbian, OSX

    Basically, my shortcoming at this point is not understanding the relationship of FourCC code (as a parameter to OpenCV VideoWriter) to the FFMPEG backend and its requirements. I am interested to understand the game in play rather than discussing a piece of code.

    What I want to know is when I specify ’X264’ as FourCC code trying to write an x.MP4 file (FFMPEG backend) and the request is marshalled to FFMPEG what requirements/dependencies need to be satisfied by the OS for it to success.

    So far I have got my python stack writing MP4 video files across Raspbian/Ubuntu/OSX, with a hack.

    On my Raspbian stretch installation, I use 0x00000021 as the fourCC code.
    On Ubuntu (VM on OSX) and on OSX, AVC1 works.

    Days of Googling only delivered those hacks, not a good understanding of the problem.

    The x264 as FourCC code leads to one of - failure, non-portable video file + annoying FFMPEG warning.

    I am trying to get to the bottom of it.

    The code,

        #self.__fourCC = cv2.VideoWriter_fourcc('x', '2', '6', '4')
    
    self.__fourCC = cv2.VideoWriter_fourcc('a', 'v', 'c', '1')
    
    if PlatformUtils.isRunningOnRaspberryPi():
    
        self.__fourCC = 0x00000021

    I have control over the version both OpenCV and FFMPEG (if required GStreamer too). I can and have built them for Ubuntu/Raspbian.

  • What video codecs work on Google Chromebook

    3 mars 2019, par MonkeyDLuffy

    I’m trying to put a show on my friends Google Chromebook but the mp4 files show up black when trying to watch them on said Chromebook, audio works fine. I found out that it is a video encoding problem but I cannot find a list of video formats that work on the Chromebook. I have ffmpeg and handbrake to try and test some things, but if someone could tell me a ffmpeg code that will convert the video files into a format that works on a Google Chromebook that would help a lot.

    What I’ve tried :

    ffmpeg -i "Game of Thrones S02E01 The North Remembers.mkv" codec mpeg "Game of Thrones S02E01 The North Remembers.mp4"

    Which gives error :

    [NULL @ 00000177196ea500] Unable to find a suitable output format for
    ’codec’ codec : Invalid argument
