Hi, it seems that the current mjpegtools package in rpmfusion is lacking a fix which is vital for encoding in LiVES: http://www.mail-archive.com/mjpeg-users@lists.sourceforge.net/msg08023.html Please could you update the mjpegtools packages with a more recent build of the code which contains the fix mentioned above. This fix should be considered critical, as users could try to encode (which will fail silently after a couple of thousand frames) and then close the original clip, causing loss of data.
