[Android] Create video from image, Video is green #216

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,

I want to create a video from some images

I use this code :

opencv_core.IplImage img = cvLoadImage("/sdcard/folder/img1.jpg");
FFmpegFrameRecorder recorder = new 
FFmpegFrameRecorder("/sdcard/folder/test.mpeg",200,150);

    try {
       recorder.setCodecID( CODEC_ID_MPEG1VIDEO);
       recorder.setFrameRate(30);
       recorder.setPixelFormat(  PIX_FMT_YUV420P);
       recorder.start();

       for (int i=0;i<100;i++)
       {
          recorder.record(image[x]);
       }
       recorder.stop();
    }
    catch (Exception e){
       e.printStackTrace();
    }

What is the expected output? What do you see instead?
It create the video well but it's all green.

What version of the product are you using? On what operating system?
Android 2.3.6

I find an answer on internet "This has been fixed in the latest 
FFmpegFrameRecorder.java" with the link of this class but i don't know how to 
fix my problem.

Any idea ?

Could you explain the procedure?

Just rename the class to something else and add it to your own project files

Ok, so i create a new class in my package named newFFmpegFrameRecord et 
copy/paste the code, but there is a lot of errors like for example 
avformat_new_stream(oc, null); who doesnt exist.

Let's see, your imageWidth is not a multiple of 16, that's probably not 
supported by MPEG-1 and the great majority of codecs...

I resize the images and it's works :)

Thank you so much !

Great! FYI, I adjusted FFmpegFrameRecorder to have it always round up the 
imageWidth to the next multiple of 16. Let me know if you have any issue with 
JavaCV 0.2, thanks!
