  • lavf : deprecate av_stream_get_end_pts()

    lavf : deprecate av_stream_get_end_pts()

    According to its documentation it returns "pts of the last muxed packet
    
+ its duration", but the value it actually returns right now is
    
(possibly guessed) dts after muxer-internal bitstream filtering (if
    
any).
    

    This function was added for ffmpeg.c, but it is not used there anymore.
    
Since the value it returns is ill-defined and so inappropriate for any
    
serious use, deprecate it.

  • Read H264 streaming from Elp H264 with OpenCV + Pyhton

    15 janvier 2017, par Francesco Paissan

    I’m trying to read an udp streaming of a H264 encoded image. The software structure is like follows :

    On a BeagleBoneBlack (Ubuntu 16.04) I’ve an Elp H264 cam (see here : https://www.amazon.com/ELP-Support-Android-Windows-Surveillance/dp/B00VDSBH9G ). I stream frames with ffmpeg on a Unicast UDP Stream.

    I want to read this images from python and opencv to be able to process them.

    I tried with this simple code to see if the cap is opened or not :

    import cv2
    try:
    
     cap = cv2.VideoCapture("udp://localhost:1234/")
    
    cap.set(CV_CAP_PROP_FOURCC, CV_FOURCC('H', '2', '6', '4'));
    
except Exception, e:
    
    print str(e)

    But when I run this script python says :

    DtsGetHWFeatures : Create File Failed DtsGetHWFeatures : Create File
    Failed Running DIL (3.22.0) Version DtsDeviceOpen : Opening HW in mode
