ffmpegX 0.0.4g
Video/audio encoder/decoder for DivX, MPEG-1/2, VCD, SVCD...

Freeware released under GPL license (included with the software).

ffmpegX is a Mac OS X GUI to ffmpeg the "hyper fast video and audio
encoder" (http://ffmpeg.sourceforge.net). It can decode MPEG-1, MPEG-2,
MPEG-4 (aka DIVX4/5), VOB, AVI MS-MPEG4 V3 (aka DIVX 3), WAV, WMA, Real
Audio, H263(+) (aka RealVideo 1.0), PGM, YUV, PPM, AC3, PCM8/16 bits,
mulaw/Alaw, SUN AU format, MPEG audio layer 2, MPEG audio layer 3,
MJPEG and even more formats. This GUI provides quick encoding to DivX,
MPEG-1, MPEG-2, MP2, MP3 & AC3. MPEG-2 encoding relies on mpeg2enc
component from the mjpegtools package (http://mjpeg.sourceforge.net).
You can convert DVD video to DivX, DivX to VCD or SVCD, and DVD to VCD
or SVCD. Includes a bitrate calculator and a mpeg splitter for multiple
CD burning. When encoding to MPEG-1 or MPEG-2 it can author the video
as VCD or XVCD (.bin/.cue files for burning with Toast by dropping the
.bin into VCD window) or as SVCD or XSVCD (two .img files to be burned
in Toast under Multitrack XA window).

System Requirements
- Mac OS X 10.2
- To playback DivX, use codecs from www.3ivx.com or www.divx.com


What's new in 0.0.4g?
- Updated to ffmpeg CVS of 2 nov 2002 with all libs and
Altivec-optimized mpeg-1 encoding (20% faster than realtime, however
still choppy, so use the new mpeg-1 VCD format for now).
- Added new "MPEG-1 VCD" format. It is similar to old MPEG-1 format
(still available in the dropdown menu, and in the presets as "fast
mpeg-1"), but mjpegtools components are used to encode instead of
ffmpeg, leading (for the current version) to a fully compliant stream
for CBR VCD and VBR XVCD authoring and playback on a compatible DVD
player. "mpeg-1 VCD" files can be dropped directly on Toast without
pre-authoring. Input formats can be Quicktime MOV in all codecs, VOB,
and the usual ffmpeg input formats. Decoding and encoding are Altivec
optimized and VOB->VCD encodes now in realtime on a G4 667.
- The mpeg-1 VCD & XSVCD presets will now use the new MPEG-1 VCD
format. The encoding options must be set in the new "VCD/SVCD" tab
(bicubic scaling, letterboxing, etc are now all functional for VCD
too). XSVCD mpeg-1 need post-processing "Author as VCD" before burning
with Toast, while VCD mpeg-1 can be directly burned on Toast. The
splitter is also fully functional for automatic multiple disk VCD
authoring.
- When using the old MPEG-1 format, the options are still in the
MPEG-1/4 tab.
- Added CBR encoding option for mpeg-2 and "mpeg-1 VCD". CBR is needed
to create a perfectly compliant VCD mpeg-1 stream which will play on
all compatible DVD players and will be accepted by Toast directly.
However if your player can handle VBR, it should be preferred, as it
will lead to constant quality streams and, with a proper quantizer
setting, possibly smaller files. If you only plan to playback the
streams on a computer there is no point in preferring CBR over VBR.
- Added new VCD, XVCD, and generic MPEG-1 profiles in the VCD/SVCD tab.
- When encoding a VOB to mpeg-2 or mpeg-1 VCD you can rename the VOB
with a ".mov" extension, that way use of Quicktime will be forced to
decode it (possibly leading to better audio sync), however audio must
be decoded separately into WAV and put in the same folder and with the
same filename before launching the video encoding, so as ffmpegX will
pick it and mux with the encoded video.
- Added DVD NTSC and DVD PAL (including 16:9) in the Autosize dropdown.
Useful to encode to mpeg-2 with the proper aspect ratio flag settings,
for later use of elementary streams for DVD authoring.
