In an earlier post I talked about settings for ffmpeg for flash video, and today I came across another helpful setting for ffmpeg.
Sometimes your video will run for 30 minutes, however you only want to upload it in 10 minute segments.
The following command will split a movie file
ffmpeg -i myfiletosplit.flv -ss 00:00:00 -t 00:10:00 mydestinationsplit_1.flv
