- yav - yet_another_video
- =======================
-
- yav is a software only video encoder/decoder for NeXT workstations. It
- will play a video with a reasonable frame size (288x224 pixels) at a reasonable
- frame rate (greater than or equal to 6 frames/second depending on cpu speed)
- with a synchronized sound track for a reasonable length of time (greater than
- 10 minutes depending on disk size). Since the above requirements necessitates
- a computationally inexpensive algorithm for on the fly decompression, the
- compressed format is not MPEG. Instead it is a format designed primarily for
- easy decompression. It sacrifices both compression ratio and quality in order
- to achieve a large frame size and high frame rate. The encoder is not real
- time and requires from 2 to 6 minutes to encode a single frame depending on
- quality. Since the design objective of yav is to implement a software
- encoder/decoder for low-end workstations in general, yav is not a NeXTstep
- application. Except for the imaging routines the yav source written in C is
- completely machine independent and should be easy to port to any UNIX platform.
- Also included are utilities to convert MPEG format movies to yav format
- movies. The MPEG convertor is derived from the Berkeley public domain player.
- Unfortunately, the only video with sound I have was captured from the TV
- and is not in the public domain. However, a converted MPEG without sound
- is included.
