  • FFMPEG Video Cropping slower [duplicate]

    23 juin 2016, par syed imty

    This question already has an answer here :

    I am trying to crop rectangular video into a square one using FFMPEG. The video conversion take too much time.

    For a video of 30 secs, it takes around 60-70secs to convert

    FFMPEG Command

    String commandStr =" -i "+videoPath+"  -vcodec libx264 -b:v 880k -vf crop=" + videoSize.height + ":"+ videoSize.height + ":" + cropStart +":0 -preset ultrafast -strict -2 " +compressedVideoPath;

  • Cannot get mp4 video to play in JavaFX app

    23 juin 2016, par CelestialCoyote

    I am trying to use the media player in Java FX to play an mp4 video. I am using the example code from the Oracle. Here is the link.

    http://docs.oracle.com/javafx/2/media/simpleplayer.htm

    I am using the same code with the exception that I want to play the video from my computer rather than going to the internet to get it. I also changed the size of the window to match the size of my video. The video was rendered using FFMPEG with the following parameters.

    ffmpeg -y -r 30 -i ’CellCellCell_Trailer_%05d.jpg’ -r 30 -pix_fmt yuv420p -s 512x512 -vcodec libx264 ’CellCellCell.mp4’

    Could not attach the video to post.

    The video plays in Quicktime and VLC without problems. In the Java App it appears to load, but does not start playing. If I move the time slider, it throws an error, otherwise it just sits there and nothing happens. The file is in a folder called ’media’.

    I have tried several mp4 videos, all with the same results. The player opens, but then does nothing. Any help would be appreciated.

    Here is the code for MediaControl.java file. It is unmodified from the Oracle example.

    avformat/http: check the auth string contents not the pointer which cannot be NULL

    It appears this bug originates from a "work in progress" patch from
    
ffmpeg-devel that was heavily redesigned by and integrated in libav
    

    And that patch even had a reply and review on the mailing list pointing
    
out that it had a bug.
    

    This fixes a deadlock with ffserver
    

    See : [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
    
     [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036
    
     [FFmpeg-devel] [PATCH 2/3] Only add Transfer-Encoding header when not in authorization phase, because server will wait (indefinitely) for data when receiving this header Partial fix #3036
    
     [FFmpeg-devel] [PATCH 3/3] Only allow posting data and/or forcing a 200 code, enabling posting isml chunks, -after- we did a possible first request to get a 403 from the server telling us which type of authentication to apply Final part fix #3036
