  • JavaCV - strange black screen when playing a file with FFmpegFrameGrabber

    17 mai 2012, par noncom

    I am using JavaCV and it's FFmpegFrameGrabber in my project. It loads and player files OK, when I launch the project from Eclipse, but shows either a black screen or a still 1st frame when I run a compiled project. Sometimes comming with this error :

    Input #0, avi, from &#39;C:/path/Start_Cut.avi&#39;:
    
Duration: 00:00:20.03, start: 0.000000, bitrate: 26002 kb/s
    
Stream #0.0: Video: mpeg4, yuv420p, 1920x1080, 30 tbr, 30 tbn, 30 tbc
    
Cannot allocate memory. com.googlecode.javacv.FrameGrabber$Exception: Cannot initialize the conversion c ontext.
    
            at com.googlecode.javacv.FFmpegFrameGrabber.start(FFmpegFrameGrabber.jav a:280)

    and sometimes with

    [mpeg4 @ 6A95DF20] Invalid and inefficient vfw-avi packed B frames detected
    
Input #0, avi, from &#39;C:/path/Start_Cut.avi&#39;:

 tbn, 25 tbc

    does anyone has a clue on this ?

    UPDATE :

    I have been able to narrow down the problem. For some reason, FFmpegFrameGrabber returns null upn calling the grab() method. Why does it work in Eclipse and does not work in standalone build ? All libraries are included and I suppose, it would come up with an error if they did not.

  • FFMPEG overlay video with black background over an image not working without any errors

    19 juin 2018, par bil80

    I have a snow effect video with black background snow.mp4, and i want to overlay it over a fixed jpeg image.jpg
    The generated output video result was only with the image without the snow effect, my ffmpeg version is : 3.2.10, i don’t understand why it is not working with me, have you an idea ?

    This is my command line :

    ffmpeg -i image.jpg -i snow.mp4 -filter_complex '[1:v]scale=1280x768,setdar=16:9,colorkey=0x000000:0.3:0.2[ckout];[0:v]scale=1280x768,setdar=16:9,[ckout]overlay[out]' -map '[out]' output.mp4

    I tried also with the chromakey instead of colorkey, without success :/

    This is the result video that i got :
    output.mp4

    What i want is this result with snow effect : output_with_snow_effect.mp4
