  • Making a video with opencv and ffmpeg. How to find the right color format ?

    17 mai 2024, par luc

    I have a webcam video recorder program built with python, opencv and ffmpeg

    



    It works ok except that the color of the video is more blue than the reality. The problem seems to come from color format of images.

    



    It seems that OpenCv is giving BGR images and ffmpeg+libx264 is expecting YUV420p. I've read that YUV420p correspond to YCbCr.

    



    opencv has no conversion from BGR to YCbCr. It only has a conversion to YCrCb.

    



    I have made some searchs and tried different alternatives to try converting opencv image to something that could be ok for ffmpeg+libx264. None is working. At this point, I am a bit lost and I would appreciate any pointer that could help me to fix this color issue.

    


  • swscale/graph : add color mapping pass

    swscale/graph : add color mapping pass

    This leverages the previously introduced color management subsystem in order
    
to adapt between transfer functions and color spaces, as well as for HDR tone
    
mapping.
    

    Take special care to handle grayscale formats without a colorspace
    
gracefully.

  • Find the streaming url source of an online streaming tv station to record with ffmepg

    20 mars 2016, par AHC

    I am trying to look into the javascript streaming source of the following site http://www.aztv.az/canli/aztv-canli.htm to capture the url and to record it using ffmpeg.

    My goal is to get something like this running :

    ffmpeg -i rtsp://XXX.XXX.XXX.XXX:XXX/live.sdp -acodec copy -vcodec copy c:/test_recording.mp4

    I don’t know what protocol this website uses, rtsp, rtmp, http, etc.
    Could you please help me to resolve this ?
    I tried to look into the .js file in the source of the page, but it is a bit complicated to figure it out. here is the js script.
