Writing AVI

[BippyM]

I have decided to resume work on My DemoDVD and booted WinUAE up to rip some intros

Anyway I set everything up (as I did when I ripped the last 40 intros I have done) and when I start I get an error

Error is:

AVIFileOpen() FAILED

This can heppen if the path and or name was entered incorrectly. Required *.avi extension.

Now I have named the file correctly Harwired.avi in this case and I have also got enough space on my HD to cope (15gb)!!

Any Ideas (This happens with 0.22r9 also, which used to work fine!!)

[BippyM]

Oh my system just in-case

Athlon XP 2700
Asus A7N8X Deluxe nForce 2
512Mb Twinforce pc3200 DDR
120Gb Western Digital 8Mb Cache IDE
80Gb IBM-Deskstar 2Mb Cache IDE
Lite-on 32x32x52 CDRW
Pioneer A05 DVD-RW
Asus V9560/TD GeForce FX 5600, 256MB DDR AGP 8x
NTL Cable Modem

Tried using WinUAE 08.22r9 and 08.23

It used to work fine on 22r9!

[hal]

possibly in use otherplace ?
or path too long ?
dunno just suggestions

[BippyM]

neither

Tried e:\hardwired.avi

also the file does not exist!!!!

[hal]

maybe going below 8.3 in filename does anything
also check if your root has a lot of small files
if so get rid of them

think i read romewhere a hard drive's root can't contain more than 512 entries
maybe that's old outdated and only applies to the fat16(or maybe even the fat32) filesystem

then i'm out of ideas

you might check the drive for errors

[BippyM]

Tried it on 2 diff HD's.. so hd is not problem

I will boot in safe mode later and try that, strange how it only affects winuae and no other avi software i use!

[BippyM]

A reformat/re-install did the trick

[Stig]

Just reporting I'm getting the same error. Is there a reason or fix for this?.

[BippyM]

yeah remove all codecs and re-install

I reckon I had a rogue codec somewhere and only a reformat fixed it

[Stig]

I can't be arsed, my XP has been tweaked to a point it's no longer Windows and applying all of these changes to a fresh install would take too long, I choose to wait till somone pops up with a less invasive solution...

[BippyM]

There wont be one!!

The problem is codec related, it isn't WinUAE that is at fault here!!!

[§ane]

Two very probable fixes for two very probable errors. System or WinUAE restart is unnecessary! Just Registry Import...

Hm, just wondering, is it possible to have WinUAE output an mpeg stream instead of .avi ? , if not (techically), why not?

Indirectly possible, pass-through one clever VCM wrapper, I would imagine. Ask Google.

It's not a feature, probably for the reason that I despise lossy Audio/Video formats, DESPISE THEM.

Besides that, supporting the AVI container, we're accommodating a multitude of formats both lossy and lossless varieties.

It worked, just added AVIFileOpen.reg and AVIMakeCompressedStream.reg, thank you, really x 10

How big is the AVI file. WB will have problems with files >2GB.
Also, Codecs can differ between different AVIs.

Use a lossless compression codec and you'll be in good shape. I personally use CamStudio Lossless, if you use the same, just make sure you set keyframes to every frame or you'll get a broken video.

I'm still working on my method to make perfect 720x576 DVD-compliant video from WinUAE, and I'm getting great results. It's been a while since I worked on it, due to the loss of my 120GB external drive, which I recently replaced with an 80GB. With CamStudio set to GZIP compression, and compression level 9, the AVI output is a bit slow, but I got 182,904,320 bytes for my raw of Funky Buddhas/Kefrens, and 540,259,840 bytes for my raw of Kefmania/Cult (of course, the techno-part of this takes up much space, and all the motion on the keftales doesn't help either). I of course record the AVIs with a window size of 720x288, normal line mode. Then I weave them together with Avisynth and encode them to MPEG-2 with TMPGEnc. I'm thinking about modifying my method to make the window a bit larger, enough room to also include the onscreen LEDs, then using Avisynth to crop the main video down and superimpose the LED display in a non-intrusive manner - that way the viewer would know that a long, blank, silent part is loading, by the fact that the drive LED is on. I haven't actually implemented this yet, so I don't know how it'd look.
