  • Create 1080p videos with javacv and ffmpeg or alternate lib

    20 novembre 2012, par 501 - not implemented

    is there a option in JavaCV to capture 1080p videos from images ?
    If i use the FFmpegFrameRecorde, i only find 480p.

    Or is there a alternate library for Java ?
    I want to use it to create a video from kind of pictures (with zooming and rotating effects)

    greetings

    //EDIT

    Okay,
    now i've tested a very simple code :

        FrameRecorder  recorder = FFmpegFrameRecorder.createDefault("out.avi", 1920, 1080);
    
    recorder.start();
    
    recorder.record(iplImage);
    
    recorder.stop();

    and it's works ! But the file is very large (10sec around 300MB...)

    Now i want to add a codec like xvid. I've get the following eyxception :

    com.googlecode.javacv.FrameRecorder$Exception: codec not found

    But i've installed the xvid paket. Must i add the codec in a special folder like the ffmpeg bin ?

  • ffmpeg - Frames flip upside-down when using -c:v copy

    7 mars 2014, par user3384390

    I tried to just copy (a period of time of) an AVI-Video into another newly created AVI-file using ffmpeg's copy option.
    (On Windows 32-bit)

    ffmpeg -i "C:\Temp\zzz\myAvi.avi" -c copy -t 00:00:10 "C:\Temp\zzz\myAviNew.avi"

    Why are the pictures flipped upside-down in the resulting file ?
    (Also the generated new audio is a little distorted.)

    Using the same command again on the newly created file will not flip them back again - the pictures stay upside down.
    Why this ? Is it a bug ?

    Console brings the following output :
