[Novalug] Video Compression

[Alvin Smith]

Here are a couple of likely candidates:


mjpegtools

MJPEG video capture/editting/playback MPEG encoding
The mjpeg programs are a set of tools that can do recording of videos and
playback, simple cut-and-paste editing and the MPEG compression of audio
and video under Linux. This package combines them with important supporting
libraries required for their use.

The "lavrec" utility supplied supports capture from Zoran based MJPEG
capture/playback cards like the Buz (Iomega), DC10 (MIRO, Pinnacle) and the
LML33 (Linux Media Labs). Compatible MJPEG avi files can also be created
using any frame-grabbing card supported by the xawtv tool.

Videos recorded in this can be filtered, editted, and converted to MPEG
streams. The MPEG encoder is optimised for high quality results at medium
to high bit-rates (1Mbps upwards) and supports MMX/SSE/3D-Now and SMP. A
Duron 700 can deliver around 15-20 352x288 frames per second.

A key design objective of the tools is interoperability with other video
tools: currently xawtv, bcast2000, nuppelvideo and vcdimager are known to
interoperate. The MJPEG utilities can read AVI, Quicktime, and movtar
streams. The MPEG encoder can produce streams suitable for buring to
VCD/SVCD using vcdimager or similar tools. The software playback of MPEG
streams works with almost every player and every OS. SSE/MMX and 3D-Now!
are supported permitting a 700Mhz CPU to deliver arond 15-20 VCD
frames/second.

advancecomp

collection of recompression utilities
AdvanceCOMP contains recompression utilities for your .zip archives, .png
images, .mng video clips and .gz files.

For recompression, 7-Zip (http://www.7-zip.com) is used, which generally
gives
5-10% more compression than zLib.
