To lay the groundwork for future updates to SciView, we have updated the version of FFMPEG that ships with Fiji. The new version is 4.1-1.4.4.
This change affects the Janelia H5J file format; a new update of that loader (Plugins › Janelia H265 Reader) has also been uploaded. For those using the H5J format: please test and report back if any issues.
I do not know whether the FFMPEG update site still works. If someone who uses that functionality to load compressed movies could please test and report back, that would be highly appreciated. (If it does not work, I can look at migrating that code into Fiji proper, rather than sitting on an old update site.)
