Summary0006379: Video files bigger than 4 GB cannot be opened
DescriptionWhen trying to open video file larger than 4 GB, the file does not open, no error is displayed, nothing happens. In the console, only "Image preview info request failed" is displayed.

The file in question was converted to AVI by Ardour itself and other files (whose resulting length is less than 4 GB) work correctly. The conversion was succesful, the resulting 5 GB AVI file can be played normally in SMPlayer.

When trying to open the same AVI file using Harvid, the file is not even displayed in the directory (other AVI files are).

This is on Xubuntu Linux.

Update: The limit is not 4 GB but 2 GB. When I converted the same file again, at 2.5 GB, it still could not be played. When I tried again at 1.5 GB, it plays OK.

most probable cause is that the video-tools are not compiled with LARGEFILE support, but it could also be a filesystem issue. I did not yet have the time to investigate.

Since Ardour also runs on windows, and some users use external disks (VFAT) on every platform the better solution is likely to avoid files > 2GB in the first place. A step towards this has been take with Ardour 4.1 (using mpeg4 instead of mjpeg to improve compression), but that's not a proper solution.
