  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

    I executed both ffprobe xxxx.mp4 and avcodec receive frame functions to decode one frame. reproduced the same error log.

    


    But when I open it using VLC or OBS it worked well. So,

    


      

    • does any error when I configure the options of ffmpeg ?

      • 


    • how to fix this problem ?

      • 


    


    the mp4 file I upload a piece in mp4 link

    


  • How to resolve the source of an RTSP server unstable problem ?

    5 mars 2021, par EricLu

    I have already build an application by gstreamer rtsp-server with its appsrc.
It's workingflow like test-appsrc. And I implement static void need_data (GstElement * appsrc, guint unused, MyContext * ctx) function using read from a IP camera's RTSP stream cv::VideoCapture in need_data.

    


    All this function is working well and it's have worked already for a day.

    


    However, I must use some algorithm deal with the IP camera source by OpenCV. When I do this algorithm at
need_data. The RTSP Server seems unstable it always print something like the below :

    


    (opencv_rtsp_server:175041): GStreamer-CRITICAL **: 15:08:38.738: gst_mini_object_add_parent: assertion 'object != NULL' failed

(opencv_rtsp_server:175041): GStreamer-CRITICAL **: 15:08:38.739: gst_memory_get_sizes: assertion 'mem != NULL' failed

(opencv_rtsp_server:175041): GStreamer-CRITICAL **: 15:08:38.739: gst_mini_object_ref: assertion 'mini_object != NULL' failed


    


    It seems the RTSP-server have losing connect appsrc.

    


    One idea to reslove this problem is imporving the algorithm as it can respond as soon as framerate is.
Maybe there are some idea about caching the output of algorithm can let the appsrc element stable.
Can some one give me some advice or trahave already build a application by gstreamer rtsp-server with its appsrc.
