First, many thanks for this stupendous piece of work. My admiration for you guys knows no bounds. I envy you your expertise.
OK. So I instantly tried out 1.6.4 on my SAA7130-based AverMedia Card.
Captured more than 45,000 frames, average frame size around 175K, 25-35% CPU useage, ZERO, that's 00.00, dropped frames. That sure beats five frames.
However:
I cannot see the video while capturing. On Preview I get a green screen, on Overlay I get a black screen and on neither do I get a picture. Audio sounds good as it is being captured and according to the stats seems to be in sync. But when done, it is dreadful, utterly garbled.
I am running capture segmented. This should, I suppose, produce a series of 2+ gigabyte files. What it actually provides is this:
File 00 2.54 GB
File 01 3.07 GB
File 02 3.73 GB
File 03 4.20 GB
File 04 0.58 GB
VDub quit capturing on File 03 with the message that a file may not exceed 4 GB in size. Also, File 04, with the same time stamp as 03, was audio only.
And finally (for now) defaults just won't stick. Practically all parameters have to be entered afresh every time.

Overlay won't work, as the SAA713x can't do full-frame capture and still send preview data. The green screen on Preview sounds like an issue with overlay and your display mode -- try switching to a different color depth or lowering your resolution. Try toggling the acceleration mode as well.

Try disabling audio resync and audio compression, if you were using it... these two probably go hand-in-hand (if audio is going nuts, the segmentation code will have problems too).

"Practically all" is useless. Give examples. Some of the settings do auto-save, while others can be saved if you go to Device Settings.

OK. What won't stick?
In capture mode:
File>Set capture file> Won't stick. "Set as default" does not work. On my system, it comes up "My documents" as default folder and no default file name. I save to a completely blank 80 GB drive and want "G:capture.avi" as default.
File>Allocate disk space> shows free space on that disk but won't allow me to specify a number. Comes up with an error "Can't seek in capture.avi." Basically, I want to allocate all the free space.
Device>Settings>Capture device options. Only "Switch audio source when changing video source" sticks. None of the other check boxes will stay checked from session to session.
On the audio: not as bad as I at first thought. I made VOB files from the captures and the audio playback was very good, though I think way out of sync. Can't be absolutely sure on that yet as the audio was voiceover on an otherwsie silent film.
I will keep playing around with this great program and report back.
P.S. Still can't make avatar work. Files are smaller than 64 x 64 and I've tried BMP, JPG and GIF formats. No go.

Is it not coming up with "G:capture.avi" as the default in the title bar (capture file), or just not coming up as the default in the file dialog? The former should be working; the latter probably is broken.

What version of Windows are you using? You can't allocate >4GB if you are on 95/98/ME....

Perhaps confusing but not a bug. Those are one-shot options, i.e. "save this now."

Fixed. Was a permissions problem on the server.

Not coming up as the default in the file dialog.

Windows 98SE. Oh, I know about the 4 GB limitation. So now I just leave this blank. VirtualDub 1.6.4 does detect free space on all drives, showing 115 GB at the moment.

OK
Progress is being made. The Preview/Overlay problem is solved. I changed the display settings color depth and resolution. to lower levels. Looked awful. So I changed them back (32 bit, 1028 X 768) and Voila! the preview window works. It is neither black nor green but dark blue.
The cascading saved file size problem also seems to be solved. If I set the capture pin at 720 X 480 the program won't stick at that setting but insists on 5xx X 480. Dropping the capture frame size to 360 X 240 does stick and at this setting capture files do not exceed 2+ GB though each file is slightly larger than the preceeding one. It's a long way from exceeding 4GB and aborting the capture. "Try not to create AVI files > 2048 MB" still does not seem to work since all the files are bigger than that.
Also, the Preview display reflects the Capture pin settings, not the Preview pin settings, which are 180 X 120. The Preview shows as 360 X 240.
By the way, or not so by the way, when I drop the capture frame from 720 X 480 to 360 X 240, will I lose quality in the final DVD, which sets the frame size at 720 X 480?
I have succeeded in capturing in one session 216831 frames without a single dropped frame. Visually, it looks excellent though the bit rate in the authoring had to drop to around 3,000 to get it all on one DVD. Don't know yet about audio sync since I had to abort the DVD creation for lack of time. Is there a faster way to burn DVDs?
PS. Thanks for fixing the avatar.

I noticed this as well. The preview pin for my DC10 is always 320x240, but when capture settings are for full-res the preview gets stretched to 640x480. |
