Any command line tools for splitting (and/or joining) video files?

By video files,i mean wmv,avi,mpg,mp4,mov,etc
all those common video formats
thanks

mencoder and ffmpeg can split many formats. I don't know if you can do any joining though.

[Baldrick]

mencoder:
mencoder -oac copy -ovc copy -ss #START_TIME# -endPos #DURATION# input.avi -o clip.avi

ffmpeg:
ffmpeg -ss 00:00:30 -t 00:00:30 -i INPUT -vcodec copy -acodec copy sub_video1.mpg

HJSPLIT 2.3 splits large MPEG files into pieces (like for upload to RapidShare or other fileshare services, most of which have maximum file size limits), or can reassemble such pieces if you are downloading them. {RAR archives also have an optional feature like this.} I don't know if it works for formats other than .MPG, and I'm also wondering if it can work in certain other situations. For example, I have some Part 1, Part 2, Part 3 etc. .AVI files that were originally part of one longer video, but were not split up in the manner I'm used to seeing, because they now exist as separately playable files. I'll have to do a quick experiment to see if HJSPLIT (or some other such utility ?) is able to put these back into one long, seamlessly playing .AVI.

You should be able to find HJSPLIT at major freeware / shareware program repositories like MajorGeeks, Tucows, or SoftPedia.

Get the command line version of ASFbin for wmv files http://www.radioactivepages.com/index.php?docid=asfbin&section=software
