- --------------------------------------------------------------
- Generic Bug's
- --------------------------------------------------------------
- + JPEG/MPEG codecs, because of their compute intensive nature, cause
- audio starvation(pops). Solution is to use +b option. Looking
- into other causes.
- + Remote Control Window colors not selectable.
- + HP support pseudo functional. Still needs a lot of work.
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.8
- --------------------------------------------------------------
- + fixed bad core dump bug in some audio section. overwriting
- a buffer.
- + SGI syncing problem fixed. Audio was block and preventing
- video from be able to play at speed.
- + A handful of minor bugs where fixed in the MPEG routines.
- Two caused corruption and one prevented bottom part of
- screen from being drawn with certain resolutions.
- + MPG wasn't properly flushing bits after a new quant scale
- + MPG if height > bug, was truncating bottom of image.
- + MPG spurious warning messages(DCT-A and DCT-B err) removed.
- + AVI RGB depth 24 support added.
- + AVI XMPG support added. This is the Editable MPEG Video
- Codec and if the spec matches the sample I have, it's
- a Kludge. The AVI Headers DON'T match(as in resolution and
- proper audio/video timing) the MPEG SEQ header which looks
- to have the correct info.
- + AVI support for "pads" streams(or rather tolerance for).
- + HP Raw audio device support to bypass upper lever HP
- audio server routines.
- + QT: minor bug in Gray Colormap generation.
- + DL animation format thrown back in and now allows it to
- be readable from the file.
- + IFF Anim8 support written by Garrick Meeker.
- + Added Quiet flag(+q) to prevent XAnim title from being
- printed out to tty. Useful when called in background by
- another program.
- + AUDIO fixed bug where anims without audio prevent following
- anims with audio from enabling that audio.
- + AUDIO Fixed scaling bug in ADPCM audio code. Affected main 8khz
- machines.
- + Fixed compile bug when compiling without Remote Control Window.
- + cleaning and simplifying internal structures. reducing global
- variables, etc.
-
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.7
- --------------------------------------------------------------
- + remodified audio/video sync code yet again. This time to
- help smooth out some startup syncing problems and to help
- handle more compute intensive video(large frame or jpeg/mpeg).
- + Added IBM RS6000 audio support - Code written by Jeff Kusnitz, thanks.
- + Fixed bug in NAS audio that caused memory corruption after
- an "unable to Toggle" warning(which occurs if a machine has
- an audio device with a fixed output).
- + Merged Audio_Outputs into one routine so I didn't have to
- keep modifying all of them(95% of the code was the same).
- + Added Dithering(+F option) to Cinepak Video Codec. It's on
- by default unless +CF4 is used(list +F after that to override).
- + Fixed Bug with some RLE depth 1 codec.
- + Fixed audio Bug with SGI generated quicktimes audio depth > 8.
- + Fixed bug that was causing quicktime to erroneously send
- back a FULL_IM flag allowing serious skipping to occur. This
- causes on screen corruption if the Video Codec doesn't
- really support serious skipping.
-
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.6
- --------------------------------------------------------------
- + Added MPEG support for Type I frames. Type B and Type P
- frames are currently skipped, but will be added in the
- future. Although I've rewritten large chunks of it, the
- core decoding routines are from mpeg_play.
- + Added Sony NEWS workstation audio support. Thanks to
- Kazushi Yoshida for writing the code.
- + Fixed some bugs in the JPEG routines.
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.5
- --------------------------------------------------------------
- + JPEG: code massively rewritten and optimized. MJPG and IJPG
- video codecs now supported.
- + CVID: some optimization here.
- + SGI: sgi hardware volume is actually exponential. Now XAnim's
- SGI volume function is also exponential
- + Sparc: had some problems with older Sparc audio devices that
- couldn't support NOT having an audio channel selected. The
- Sparc audio ports are now radio button style.
- + Sparc: Some serious incompatibility problems between gcc/cc
- and the /usr/includes and gcc's /usr/includes. Fixed for now.
- Was causing ioctl err 22's during run time on certain
- machine configurations.
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.4a
- --------------------------------------------------------------
- + ALL: You can now add sound to animations that don't have
- sound support(ie FLI/FLC/IFF) by specifying a .wav file
- after the animation file. ie "xanim bart.fli laugh.wav".
- Only some .wav audio compression are currently supported,
- more on the way. NOTE: if audio is longer than animation,
- then animation waits on the last frame until audio is done.
- +f option currently doesn't affect .wav files.
- + PC: best variable not defined in Linux_Closest_Freq() err.
- + PC: libjpeg.a already used by the system and was being found
- 1st by the linker causing errors. Renamed to libxajpg.a.
- + ALL: Solution that helps high frame rate anims on SGI machines
- was hurting some others. Now only fixed on SGI machines.
- + ALL: work around to help play some broken FLC's.
-
- --------------------------------------------------------------
- New(or Fixes) to 2.69.7.4
- --------------------------------------------------------------
- + Fixed bug with Quicktime signed(TWOS) 16 bit stereo audio format.
- + Fixed bug with +f option and any 16 bit audio format.
- + +Ae is now be made enabled by default.
- + SPEAKER env variable checked(INTERNAL/HEADPHONES/EXTERNAL/NONE).
- + RemoteControl Window made smaller and now has dynamically
- changing bitmaps to better indicate current function of
- the buttons.
- + RemoteControl window no longer overlaps Anim Window.
- + "+Ar" option enables/disables RemoteControl Window.
- + "z" window command pops creates/destroys RemoteControl Window
- on-the-fly.
- + More fine tuning of video/audio routines.
- + AVI ADPCM is no longer decompressed 1st. +f now works with
- this audio codec.
- + AVI JPEG Video Codec support added, including interleaved frames.
- + AVI MJPG Video Codec support added.
- + HP: finally code sound out of an HP. Code still has a ways to go.
- And HP Aserver library seems to be part of the problem.

- Configuring For Your Machine
- --------------------------------------------------------------
-
- You'll need to edit the Makefile or the Imakefile. Go to the Audio
- section and uncomment out the DEFINE's associated with your machine
- type. Make sure no other machine's DEFINE's are uncommented. That
- would be bad.
-
-
- --------------------------------------------------------------
- Sun Sparc Specific Info
- --------------------------------------------------------------
-
- IF YOUR ARE USING OPENWINDOWS THEN YOU MUST USE Makefile.unx
- AND YOU MUST EDIT THE CHANGES REQUIRED. This is because of
- bugs/deficiencies with the OpenWindows Athena libraries.
- See top of Makefile.unx for more details.
-
- Having some problems with gcc, because it wants to use it's
- own include files and they're usually wrong(or out of date).
- Use cc if this happens.
-
- If you are using Solaris, use the -DSOLARIS define in the Makefile.
-
- --------------------------------------------------------------
- Linux(soundcard) Specific Info
- --------------------------------------------------------------
-
- Compiles and runs on 8 bit and 16 bit sound cards(sound driver 2.5 and 2.99).
- Some video/audio syncing problem with driver 2.5 that got better with 2.99.
-
- --------------------------------------------------------------
- SGI Specific Info
- --------------------------------------------------------------
-
- NEWSFLASH. The audio stuff should be included now in Irix 5.3. You
- might be able to obtain them for free if you have the Irix 5.1 or
- Irix 5.2 releases, but that's just a rumor.
-
- If you have Irix 5.1 or greater then make sure you have installed
- the digital media development subsystem (dmedia_dev.sw.audio) off
- of the CD-ROM.
-
- If this isn't on your CD_ROM then read on...
-
- "according to the 5.2 readme first page, it says
- that the Audio Development software has been moved from
- the IDO to a purchasable option, IRIS media libraries. "
-
- And you either have to contact SGI and buy it($495) OR
-
- In the meantime, you can compile XAnim on an Irix 4.0.5 machine
- and the XAnim binary should work back on the original Irix 5.1
- or 5.2 machine.
-
- Once XAnim audio is stablized on SGI's, I should be able to provide
- an xanim executable. NOTE: I don't have nor can I legally distribute
- the SGI audio libraries and include files.
-
- --------------------------------------------------------------
- HP Specific Info
- --------------------------------------------------------------
-
- Written and getting better, but still has a ways to go.
-
- With HP's you need to start up the system Audio Server before
- you can use ANY audio program. Here's how(from the Audio.man
- page on an HP 700/915):
-
- Step 1. Start the NCS Local Location Broker Daemon.
- Task 1. If you are not already superuser, log in as
- superuser.
- Task 2. Enter the command line /usr/etc/ncs/llbd&&&&.
- To make llbd start automatically at boot
- time, edit the file /etc/netncsrc and change
- the line START_LLBD=0 to START_LLBD=1.
- Step 2. Reboot.
- Step 3. Set the AUDIO environment variable to specify the node
- where the audio client should look for the audio
- server. If AUDIO is not set or if it is set to :0, the
- client connects with a server on the same node.
-
- To specify that the client should connect to a server
- on another node, set
-
- AUDIO = node_name: (Korn, Bourne, and POSIX
- shells)
- export AUDIO
-
- or
-
- setenv AUDIO node_name: (C shell)
-
- Step 4. Normally, the audio server starts whenever the system
- is booted. Check for the existence of the Aserver
- processes by typing
-
- ps -e | grep Aserver
-
- You should see two Aserver processes. If the server is not
- running, start the audio server by hand by typing
-
- /usr/audio/bin/Aserver
-
- Then type
-
- ps -e | grep Aserver
-
- and check that there are two active server processes.

- IBM RS6000 Specific Info
- --------------------------------------------------------------
-
- Waiting for feedback on how it works.
-
- --------------------------------------------------------------
- AudioFile (AF) Specific Info
- --------------------------------------------------------------
-
- I haven't brought up AF yet on my machine, but have gotten
- reports that it works okay.
-
- --------------------------------------------------------------
- Net Audio (NAS) Specific Info
- --------------------------------------------------------------
-
- I have brought NAS up on my machine and have fine tuned it. NAS
- has some deficiencies that make it difficult to keep audio/video
- in sync. Hopefully they'll improve it and likewise I'll improve
- my understanding of it and work from there.
-

- Any comments, questions, bugs, fixes, etc email me at
- podlipec@wellfleet.com or podlipec@shell.portal.com
-
- If you make changes to the audio code, please send entire
- xanim_audio.c file unless the patches are minor.
