Decompression

Compression
Fast integer Fast integer method. This method is the fastest but considerably less accurate than the other two; its use is not recommended if high quality is a concern.
Integer Slow but accurate integer algorithm.
Float Floating-point method. This method is slightly more accurate than the 'slow' integer method.
MMX If grayed MMX is not detected.
If checked, MMX optimizations are used.

MMX optimizations :

  • Inverse DCT and dequantization on fast integer and integer methods.
  • Upsampling, color conversion and merged upsampling and color conversion for all methods (even with fancy upsampling).
 If grayed MMX is not detected.
If checked, MMX optimizations are used.

MMX optimizations :

  • Forward DCT management and quantization on fast integer and integer methods.
Fancy upsampling If checked, do careful upsampling of chroma components. If unchecked,a faster but sloppier method is used.  The visual impact of the sloppier method is often very small.

N/A
3DNow!

N/A

 If grayed 3DNow! is not detected.
If checked, 3DNow! optimizations are used.

3DNow! optimizations :

  • Forward DCT on float method.
Enable codec If checked, the codec is enabled, if not it is disabled.
User FourCC If checked, the text in the edit box is used as the default FourCC for both compression and decompression.
  • Matrox Rainbow Runner users should check it and type dmb1 in the edit box if nescessary.
Enabled If checked, decompression is enabled, if not the codec reject every query for decompression. If checked, compression is enabled, if not the codec reject every query for compression.
Support Interleave Apply only if height is more than 288.

If checked, decompress and display 2 interleaced fields per frame.

If unchecked decompress and display only the first field (odd lines). Odd lines are duplicated to fill even lines.

 Apply only if height is more than 288.

If checked, compress 2 fields per frame (2 JPEG images are stored, one per field, for each frame).

If unchecked compress and srore only the first field.
Invert Field order Odd lines become even lines and even lines becomes odd lines.

Take a look at The MJPEG-Software-Codec Guide by Uwe Roeder, a very interesting text about using software codecs coexisting with hardware codec. The mentioned hardware is the Rainbow Runner, but there's many informations for other hardware users.

FourCC issue

MJPEG hardware in the PC

Warning on installing the Morgan Multimedia MJPEG codec(*)
MJPG The most common (Fast, Miro, Iomega, ...).

If your hardware handle the 'MJPG' FourCC, you should find the key "vidc.mjpg=..." in the  [Drivers32] section of the SYSTEM.INI file.

 Before installation, edit the SYSTEM.INI file and add a ; (semilicon) before the line "vidc.mjpg=..." of the  [Drivers32] section.

Then install the MM-MJPEG software codec.

To reactivate the hardware codec, remove the previouly added ; and add a ; before the line vidc.mjpg=m3jpeg32.dll

Use a similar method to reactivate the software codec.
dmb1 Matrox Rainbow Runner. You can install the MM-MJPEG software codec.

But before adding the dmb1 support, edit the SYSTEM.INI file and add a ; (semilicon) before the line "vidc.dmb1=..." of the  [Drivers32] section.

Add a line vidc.dmb1=m3jpeg32.dll in this section.

To reactivate the hardware codec, remove the previouly added ; and add a ; before the line vidc.dmb1=m3jpeg.dll

Use a similar method to reactivate the software codec.
jpeg No known hardware, used to playback QuickTime (4:1:1) 'jpeg' streams.

N/A

(*) This apply only for Windows 95/98.
For Windows NT, DO NOT install the codec on the machine containing a capture device that handles 'MJPG'.
Except if you are using a Matrox Rainbow Runner wich handles neither 'MJPG' nor 'dmb1' FourCC under NT.
It seems that the DC30 does not install an 'avicap' driver under NT, so maybe could you use the software codec coexisting with the hardware device but it was not tested yet. Email me if you try it ...
If you are sure of what you're doing, you can modify the provided OEMSETUP.INF file before installation.

  • Tested for decompression only.

  • Benchmark program :
    Modified DirectDraw sample called Avidd.
    Test the frame rate with 3 methods.
    1 - NoDraw : No display is performed, it give you the pure frame rate of the codec.
    2 - DirectDraw : Display with DirectDraw (YUV modes only).
    3 - DrawDib : Windows choose the best display mode, depending on the displau settings and the codec capabilities.

  • AVI file : 320 x 240, 24 Bits, 207 frames, 30 fps, 167 Kb/Sec, MJPEG compressed @ 50.

  • PC :
    MB asus P2B 440BX bus @ 103Mhz
    PII 333 oveclocked @ 412Mhz  (4x103)
    128Mb sdRAM
    Matrox Millenium II AGP 4Mb + Rainbow Runner (not used to decomp 'MJPG' ;-) it only decomp 'dmb1'...)
    Seagate Medialist 6.4Gb UDMA2 + Intel PIIx Bus Master
    Windows 95 OSR2.5 + DirectX 6 + Direct Media 5.2b

  • I'm still looking for a more pro and standard benchmark program for AVI codecs ... If you know one, email me at m3jpeg@morgan-multimedia.com
