[ome-devel] "RE:Re: Problem extracting videos of a lif project "larger than 4GB

[David Gault (Staff)]

Hi,

I have been able to run some conversion tests today using .lif files >4GB and have not been able to reproduce the same issues yet. The fact that providing the height and the width during the reading of the images changes the behaviour is rather odd as internally this should be doing the exact same thing as before.

I have created a short example program which should convert files, saving each plane to a new output file. If you could test using this code and see if you are still seeing the same issues as before that would be a good start https://github.com/dgault/bio-formats-examples/blob/dalsim-eresmas-example/src/main/java/ConvertPlanes.java

If you are still experiencing the same problems then we will arrange a way for you to provide a sample file so we can further test the issue.

With Thanks,
David Gault

So, with this solution the problem is not solved. However, if I force to open with height and width I want like:

     reader.setSeries(jj);
     w = reader.getSizeX();
     h = reader.getSizeY();

     [.....]

     writer.saveBytes(0, reader.openBytes(image,0,0,w,h));

Then, I can always open and see correctly in FIJI any frame saved with writer even if the .lif  > 4 GB. BUT if .lif project is > 4GB then, I cannot see the file saved with writter directly in windows and ffmpeg is prompting me "Invalid TIFF header". If .lif project is < 4GB, I can see it directly with windows and ffmpeg is not prompting me any error. Any idea?
