encaudio60 ntsc_au < gold_au
Should do it, assuming your gold_au file is the 60Hz export of the audio from VirtualDub.

Where does one find the files a8_ntsc.vdscript and a8_pal.vdscript?

Where do I find encvideo50n.exe, encaudio60.exe and muxvideo50.exe?

In the folder posted by Avery

http://atariage.com/...de-2/?p=2747884

there are encvideo50n.cpp and encaudio60.cpp.

 

I found a8_ntsc.vdscript and a8_pal.vdscript here: http://atariage.com/...de-2/?p=3721294

here are all the files you need to convert/test a video to stream from a CF card on a Windows based computer

It works!

 

I have three problems (PAL):

 

1. at the end of my video (or downloaded ones like Dragon's Lair intro) I get this message on Atari: "Read error 5100 E0E0E0E0"; perhaps it's normal.

EDIT Doesn't happen on real hardware.

 

2. I download videos from youtube with this online tool: https://www.onlinevideoconverter.com When I try to convert them with VirtualDub, first I get the message "AVI: variable bit rate audio detected", then when I try to save as AVI I get the message "no audio decompressor could be found to decompress the source audio format".

 

3. nowadays many video files are MKV and not AVI; what should I do to load them in VirtualDub?

just look for an MKV or MP4 to AVI converter tool to port your videos to AVI

Yesterday I've done it (XviD4PSP) but I have problems with audio (see my problem #2).

Do you know why every few seconds there's an audio and video noise?

Perhaps I have to change CF card?

I'm having major audio issues with my conversion, but also some existing ones.  Doesn't seem to matter if it's NTSC or PAL.  There's a nasty "clicking" or hum.  It's not like the audio is too loud.  When trying the latest Altirra, the problem is even worse.  I may have to post video to show.

To remove audio and video noise that happen every few seconds (see previous post), I bought a SanDisk 16GB Ultra but it doesn't load the video.

Perhaps it's a too big CF card?

When I turn on the computer, with the other working CF card, I get the message "Invalid partition table" before SpartaDos copyright message.

With this non working CF I get the message "Disk error".

The audio glitches I am talking about are constant though - i I had to guess by listening to it, I'd say a click at the start of every frame.

Problem solved with a new card.

Transcend 1GB every few seconds has an audio and video noise, SanDisk 16GB Ultra is incompatible with Side2, SanDisk Ultra II 1GB is perfect.

I'll have to order some new cards.  I've had nothing but success with my Transcend 2GB cards with all of my devices (IDE2+, SIDE2), but this video player must really thrash the hardware (I mean that in a good way) because I get a lot of errors when just trying to initialize the player.

The video player is moving several hundred KB/s (yes: kilobytes) off the card as opposed to the c. 60KB/s of which the CPU is capable, so yes: it gets thrashed. :)

 

Haven't used Transcend cards for five years or more after I realised they wouldn't work reliably with anything I had. Low-capacity (1GB-4GB) Sandisk Ultra/Ultra II is the way to go.

WoOoW !!!

 

Got working the Incognito-mapped version correctly, but must mount / load the player directly as executable (generated an .ATR version that did not work). CF Card is SanDisk Extreme-III (2GB). Also got it working without a hitch, on SIDE-I and SIDE-II carts on 800XL.

 

The VP930 LCD / DVDO iSCAN-HD combo seem to render the streaming without a sweat, very sharp, and relatively vivid colors, although I definitely prefer the "virtual-colors" rendered in Composite mode (both Y/C and Composite can be inspected real-time, and below are the vis-a-vis examples of TRON, first composite and then Y/C (sVideo)). On the Sony large-CRT (Wega) it looks crappy.

Anyhow, just amazing, to say the least... I do not believe the HW could have been pushed to these limits back in early-mid 80's... or even later... I don't recall any storage solution with a form-factor and performance combination appropriate-enough for extracting so much juice out of the Atari platform. I wonder what Jay Miner & Team (including Doug Nubaer) would say if they could see this...

 

Kudos for such AMAZING 5K of code!!!  :-o  :grin:

SURE!

 

Here's Dragon's Lair, probably best NTSC encoded sample here (please, force quality to 480p).

 

Playback from A800's composite signal (via DVDO iScan-HD processor). It was impossible to get white-balance right during recording (my apologies):

 

 

 

Hey! I could even see the A800's RF modulator output on Channel-3: :grin:  ;)

 

 

 

Enjoy!

The screen is IR mode 2 (40 column hires) toggled between modes 9 and 11 via PRIOR on each scanline.

Correct me if I am wrong.

192 pixels vertical resolution and 80 horizontal resolution, alternating modes 9 and 11?
