mp4 files

[Zeev Smilansky]

I'm analyzing some MP4 files from the net. They only load via LOCI tools from 2008 (and NOT by the latest version). The video plays nicely on the screen, but I can't access the color data. Type is GRAY32. Status bar shows a float number as pixel value. In the debugger three channels can be seen, one in the regular ImageProcessor, two others in a field called "otherChannels" which is ImageProcessor[] of length 2 and does have the right data buffers.
Any suggestion will be appreciated.... how to access the "otherChannels" field or how otherwise to read such files. It's just an ordinary file type, like billions of others.
thanks
Zeev

Could you upload one sample, maybe via Fiji's Help>Upload Sample File? The
Bio-Formats developers have access to the uploaded files and I am sure
that having an example file will help resolve the issue pretty quickly.

Hi Zeev,

Thanks for uploading the sample MP4 files!

I was able to successfully read the file
"hahahaha_Baby_gets_out_of_crib.mp4" with the latest version of
Bio-Formats, when running Java in 32-bit mode. The reason is that to read
this kind of file, Bio-Formats uses the QuickTime for Java library, which
is only available from 32-bit Java. Additionally, on Windows, you must have
QuickTime installed.

For a list of supported codecs, see this page:

Please let us know if you experience different behavior.

HTH,
Curtis
