 newFFmpegFrameRecord recorder = new newFFmpegFrameRecord("video"+System.currentTimeMillis()+".mp4",320,480);

i am using this line to give a height and width for a video.

I don't think FFmpeg supports dynamically changing image sizes. If you want to 
resize your images, you can do that with cvResize(). Is this what you want?

Hi samuel,

What i need is i have captured some images from device. from that 5 images are 
portrait screens and another images are landscape images. so as per the 
orientation our video size should get change . For this only i am searching 
solution and asked whether we have dynamic image size changing facility or not 
??? 

i mean while showing the landscape images our video size should get changed as 
per the image size. 

Thanks ,
Rajesh K

We can use cvTranspose() to transform a landscape image to a portrait image, or 
vice versa. Is this good for you? Please ask your questions on the mailing list 
next time, thank you
