Probably the world's most popular MPEG-4 codec, DivX, has been updated.
The new version, DivX v5.04, includes various bug fixes and improvements over the last (v5.03) version. The full changelog is here:
  • Changed:
    • The new RC doesn't use Q=1 frames anymore
    • No stuffing used, bitrate can be too low in some extreme cases.
    • Strategy planning for rate control is much faster now
    • Better tracking of the planned RC strategy creating more consistent quality.
  • Fixed:
    • K6-2 CPU related crash resolved.
    • Not able to change Bitrate Modulation through CLI field.
    • During 1 pass quality-based, Quantizer can now be set to 1 with CLI
    • Multiple error windows no longer open upon entering wrong bitrate modulation option.
    • 'Max Keyframe Interval' no longer accepts negative values
    • Multiple error windows no longer open upon entering wrong CLI option.
    • In the Quick Config CLI field, 'Enable Resize' was taking invalid options
    • Fixed CLI inconsistencies when "Restore codec's default" is pressed.
    • Max bitrate and encoding bit rate(average) was displayed same.
    • Fixed hitting tab in the CLI field to enable 'Use Bidirectional Encoding'
    • Fixed: remove -w in the Quick Config CLI field, 'Update Log file' option is not getting deselected.
    • When 'Psychovisual Enhancements' value is set to 4, in the Quick Config CLI field, mismatch in slider and label options.
    • 1 Pass and Nth Pass undersized file should be fixed
    • Certain dark sequences would produce a long period of frames using a Quantizer of 31.
    • Psychovisual Enhancement field sometimes displayed "Custom" instead of Light when unselected
    • "Do not prompt with errors and warnings" would select itself when random characters were entered in the CLI after the "-key" option
    • When "-d 3" option was entered in the CLI field, "Source interlace" became blank.
    • Max bitrate would not update at times.
    • DirectShow decoder postprocessing slider became disabled with ATI radeon 9700 Graphics card
    • DirectShow decoder would "fast forward" when seeking backwards. This could cause synch issues when re-encoding DivX Files using the DivX Decoder Filter.
    • Various cosmetic fixes in the Encoder GUI
      • Do not prompt Error unchecked as default fixed.
      • Light Psychovisual enabled itself automatically when exiting the CLI field.
      • Max bitrate reset itself to x10 the average when going in the "profile" tab
    • MPEG-4 "type Indicator" correctly set according to selected encoding parameters
    • No more green first frame at very high bitrates.
    • Decoder updates the display to the appropriate frame when seeking
    • Decoder remembers the postprocessing settings
    • Fixed some memory leaks related to Psychovisual and Nth Pass™ mode
    • Nth Pass RC is tweaked to minimize the usage of high quantizer
    • Nth Pass doesn't create an empty frames at the beginning of the clip
    • Brightness/Saturation sliders now working correctly.

dRD, mpeg-4 is a worthy format (and capable too), but in truth, unless one is willing to sit hunched over their keyboard watching stuff on their computer monitors, what good is it? (really). Only the merest fraction of independent hardware manufacturers support standalone mpeg-4 playback, right? (Divx, an mpeg-4 derivitive, is also DRM-inhibited). It may or may not be as bad (pitiful) as .wma, but I just can't easily tolerate crippled, restricted formats.

I lost interest in DivX when it went closed source. To encode using the pro version, either one must purchase it now or have that annoying GMT adware process installed. Going by the top downloads on Afterdawn, it appears most are switching over to XviD.

I still believe strongly that MPEG-4 has a future, but not in the stand-alone living room devices. I'm a strong advocate of totally wireless computing and I've written tons of articles to various publications about my beliefs that the TV and radio as we know will disappear within a decade or so and will be replaced by IP-based devices, whether they look exactly like our old TVs or are handheld mobile things that connect to the Net via IPv6 & 4G+ networks. Once the average bandwidth that virtually every Western household has, via mobile or via cable/VDSL/similiar, is around 10-100MBps (some countries are there already -- some countries call 128k ISDN a 'broadband'), transferring DVD-quality MPEG-2 over the Net in real-time is piece of cake. This can be achieved with slightly lower bandwidth by using MPEG-4 instead -- but then again, it needs tons and tons of standardization before it is anywhere near usable for any mass-market purposes.
