If you +want to discard a section of the video, you can specify +the +.I file +/dev/null. +.P +All specified +.IR end-point s, +including +.RB ' end ' +must be in strictly ascending order. +.P +The specified +.IR file s +may be of any type, except directory, including pipes +and FIFO:s. Indeed you probably want all of the to be +pipes, as saving a raw video to disc will probably fill +your disc almost immediately. If you are levering the +power of +.BR make (1) +to only rerended parts you have changes, you can +pipe the videos into +.BR blind-to-video (1) +to compress them. If you're shall does not support +process substitution or creating anonymous pipes, you +can uses FIFO:s. If you try to truncate a FIFO, it +will be flushed, if this is done after all writes have +been done, the process reading from the FIFO will think +that there no longer are any processes that have it +open for writing, assuming it, like all +.B blind +tools, have been written to treat the file as any a +regular file (which is usually have pipes are also +treated). +.SH OPTIONS +.TP +.B -L +Ignore the number of frames specified in the videos head +and read until the end or the last desired frame is reached. +If this option is used in combination with +.RB ' end ', +the last video will have an incorrect frame count written +in its head. Depending on what tools you will being using, +you may need to save that video into a regular file and +rewrite its head with +.BR blind-rewrite-head (1). +.SH AUTHORS +Mattias Andree +.RI < maandree@kth.se > -- cgit v1.2.3-70-g09d2
