movie thumbnailer (mtn) -- saves thumbnails (screenshots) of movie or video files to jpeg files. it uses libavcodec as its engine, so all popular codecs, eg. divx h264 mpeg1 mpeg2 mp4 vc1 wmv xvid, and formats, eg. .3gp .avi .dat .mkv .wmv are supported.
Please add x265 support ,I suppose you need to update libraries , you know much better regards ARIO
