vidtools: for processing streams of video images

abktovid reads an 8mm tape dump of an Abekas frame store and writes a video stream to stdout.

To skip 10 frames and then read 100 frames do:
abktovid 100 |

To make a stream out of several image do:
tovid 00.rgb 01.rgb 02.rgb 03.rgb 04.rgb 05.rgb |

To put the compressed movie sample.mov on a video stream do:
movtovid sample.mov |

vidpaste displays images from a video stream on the screen.

Here's an example command:
| vidpaste

This command will create numbered images with names like seq000.rgb, seq001.rgb, and so on:
| fromvid seq

To take 25 images and make a 5 by 5 array do:
| vidarray out.rgb 5 5

This can be an interesting way to look at an animation.
| vidsmear out.rgb

| vidtomov out.mov

viddiff differences sequential frames.

This will difference each frame with a frame from 3 frames ago.
| vdiff 3 |

This command echos from 5 frames ago, with a blend factor of 0.5:
| vecho 5 0.5 |

This example runs the script "process" for each image. The script process should apply some processing to the image in $1 and leave the result in $1.
| videxec process 1 |

To flip all the video frames from left to right The script "process" could look like this:

iflip $1 t.rgb mv t.rgb $1

This will hold and image for 4 frames and blend it with a factor of 0.4:
| vidhold 5 0.4 |

This example will take 20 frames and blend the last 4 frames over the first 4 frames making a continuous loop of video.
| vidloop 20 4 |

This command will double the frame rate while scaling the size of the video images by a factor 0.67 in x and y.
| vidzoom 0.67 0.67 0.5 |

This will take 46 frames on input and create 12 frames on output.
| vidzoom 1.0 1.0 `wantn 0 46 12` |
