  • Opencv 3.1 compiled with FFMPEG, but won't open https urls

    2 mars 2018, par stalagmite7

    I work on a 16.04 system, and have successfully installed opencv 3.1 with FFMPEG flags enabled. I double checked this was actually the case by cv2.getBuildInformation() and I got FFMPEG = YES.

    I am trying to open a video that is hostel on a private server by my workplace (I am logged in to the VPN, in case thats a concern) and I can access this video over the browser. But videocapture with cv2 fails.

    >>> cap = cv2.VideoCapture("https://xxx.mp4", cv2.CAP_ANY) #dummy url
    
>>> cap
    
<videocapture 0x7f63300fa4b0="0x7f63300fa4b0">
    
>>> cap.isOpened()
    
False
    
</videocapture>

    This is always the case for https urls. It seems to be able to work with local videos just fine. I have tried a bunch of different thing : initially thought it was a gstreamer problem so I checked my plugins, had some gst-bad versions (ref : https://github.com/GStreamer/gst-plugins-ugly), removed those and replaced with good versions, no joy. Also tried to explicitly tell videoCapture to use cv2.CAP_ANY and cv2.CAP_FFMPEG flags while reading the video, still no luck.

    I disabled the Gstreamer flag while compiling opencv, but even with it set to ON, there was no difference in my problem.

    I haven’t been able to find a solution to this issue and have been looking and trying different things for days now ! Any ideas ?

  • c++ ffmpeg api get video stream from https link

    16 avril 2014, par Chabloz

    I'm trying to read https video link using the function av_format_open_input() but the function return a negative value.
    Here is my code :

    av_register_all();
    
avcodec_register_all();
    
avformat_network_init();
    
const char * url = "https://r1---sn ...";
    

    
AVFormatContext * pFormatCtx = avformat_alloc_context();
    

    
int ret = avformat_open_input(&amp;pFormatCtx, url, NULL, NULL);

    This code worked with a local file as url but as soon as I give a https url it doesnt work anymore.
    thanks
    [edit]
    I found only this : ffserver.c
    But it uses a .ffm file as input. Any exemple or help on how to implement HttpContext (if HttpContext is needed here) would be great.
    [update]
    I ended using libvlc which seems to be much easier but the way to do it using ffmpeg could still be interesting. See my other post if interested : Get frame from video with libvlc smem and convert it to opencv Mat. (c++)
