error opening video file

[Rodrigo Gonçalves]

Dear all, I'm getting an error when trying to open a 16.7 MB mp4 file. See below information about the video file as shown by VLC:



When I try to open it using FFMPEG (Movie) option in Fiji, I get the following error:
— start of error message —(Fiji Is Just) ImageJ 2.0.0-rc-69/1.52t21; Java 1.8.0_172 [64-bit]; Linux 5.3.0-24-generic; 1733MB of 17321MB (10%)

Any help is welcome, thanks!!Rodrigo

Hi Rodrigo,

Thanks for the bug report!

Wayne: It looks like the FFMPEG plugin code passes a null path to the
VirtualStack constructor; see:

https://github.com/scifio/scifio-javacv/blob/ffmpeg/plugin/src/main/java/fiji/ffmpeg/IO.java#L151

Would it be possible to update the VirtualStack code to handle null paths
gracefully?

Regards,
Curtis
