Hi Dave
I have played a bit with a few options and found the problem.
It comes back to the ratio/pixel format of the input JP2 frame
My input pixel is 720*576 and the downloaded file is 640*480.
My first step was to expand it to a different format like tif with:
kdu_expand -i PCC_frame00x.jp2 -o out.tif -region {0.0625,0.0},{1.0,1.0}
The 0.0625 = 1 - 540/576
Then convert it back to JP2 format with:
kdu_compress -i out.tif -o PCC_frame00x.jp2 Creversible=yes Clayers=16
(I still need to fine tune this command)
And then I can use the merge command:
kdu_merge -i frame000.jp2,frame001.jp2,frame002.jp2 -o Avideo.mj2 -mj2_tracks P:0-2@25
Now I can open the Avideo.mj2 file with vlc player in windows. I did try it this morning in the linux version of VLC but it fail with a unknown format.
I did only 3 frames but will expand it.
Thanks for your input Dave.
If you can maybe give me a more elegant solution it that will be great.
Is there perhaps a way to do this:
kdu_expand -i PCC_frame000.jp2 -o out.tif -region {0.0,0.0},{1.0,1.3333333}
I want to keep all the data in the JP2-file and not lose some. Even if I get a 2 black side...
Thanks
