  • Get mime type for MediaSource.isTypeSupported

    11 mars 2024, par Guig

    How do I get the Mime type I need to pass to MediaSource.isTypeSupported with ffprobe/ffmpeg ?

    



    For instance, on my computer, that returns true :

    



    MediaSource.isTypeSupported('video/mp4; codecs="avc1.64000d,mp4a.40.2"')


    



    while that doesn't

    



    MediaSource.isTypeSupported('video/mp4')


    



    I'm not sure how to get what would correspond to the avc1.64000d,mp4a.40.2 part for a given video. Here is a larger list of what this part may look like.

    



    ffprobe -show_streams -i video.mp4 returns a number of interesting informations, including

    



    codec_type=video
codec_time_base=1/40
codec_tag_string=avc1
codec_tag=0x31637661 


    



    and

    



    codec_type=audio
codec_time_base=1/48000
codec_tag_string=mp4a
codec_tag=0x6134706d


    



    I'm not sure I should go with 'video/mp4; codecs="avc1.0x31637661,mp4a.0x6134706d"' since this returns false and I don't know if it's because it's not the excepted argument or because the video is indeed not supported.

    hls : skip to next segment if the current is unavailable

    Apparently, some live streams can delete segments too early, maybe
    
because the client is too far behind. In this case, it’s better to skip
    
the segment, instead of returning EOF. (Yes, the HLS demuxer actually
    
returns AVERROR_EOF if opening the segment returns a 404 HTTP error.)

  • How to decode RTSP h264 stream from IP camera using C# and EMGUCV ?

    9 janvier 2020, par xor31four

    I am trying to access a H.264 stream on an IP camera within my LAN via EmguCV Video Capture. There is an RTSP URL containing the h.264 stream and an HTTP URL that transmits MJPEG.

    The goal is to perform perform some EmguCV video processing operations on a live stream in as close to real-time as possible.

    I have a bandwidth limitation of 10Mbps.

    The problem is that Emgu.CV is unable to open the rtsp(h264) stream but perfectly capable of opening the http(mjpeg) stream..

    I can’t use the mjpeg stream as it consumes too much bandwidth and I drastically lose picture quality and fps.

    I need to access the h.264 stream in order to meet my bandwidth requirements

    Here is the code that I use to check whether the capture has been created :

                string MJPEG_URL = "http://192.168.0.11:35271/image1"; //returns true
    
            string RTSP_URL = "rtsp://192.168.0.11/stream1.sdp"; //returns false
    

    
            _cam1 = new VideoCapture(RTSP_URL, VideoCapture.API.Any);
    
            var flag = _cam1.IsOpened;
    
            Console.WriteLine(flag);

    RTSP_URL returns false. But when I enter the exact same URL in VLC Player, or if I use VLCSharp library to access the stream it works.

    Any suggestions ?
