Hello.
This is my first ticket.
I want to capture in ffv1 10bit. But it always crashes.
I use decklink studio 4k.

I tried several cases:

opening VirtualDub64.exe:
It crashes when defining the decklink device (report attached)

opening VirtualDub.exe (32bit):
I can define the decklink card as device.
When I put the parameters to 8 bit ans uncompressed it works.
When I choose 8 bit ffv1 the test video capture works but the ral capture crashes (report attached)

When I change to 10 bit its the same.

But it works with Huffyuf.

It seemed to be a problem with ffv1 as capture format.

Happy for any help, advice or/and debugging.
Hermann

    Hi, crashes for me too. Until I fix this, please try some older VD2 releases, I'm sure it worked before.

    This build fixes at least one problem, check if it works for you.

    I think I'm running into the same issue:
    Capture works in 32bit version, but 64bit version crashes immediately when selecting the "Capture > Capture AVI..." menu.

    For some strange reason, I cannot save any crash report (just a message saying "Save failed." when I click on the "Save button"), so I've attached screenshots. Sorry :(

    Hardware is Blackmagic Decklink SDI 4k card.
    Virtualdub2 build 44282 on Win10.

    Thanks in advance!

    I just started experiencing this too. I'm using the 64bit version and I'm also capturing into FFV1.3 via a decklink card. I've tested with 32 and 64 bit Virtualdub2 ver 44282 and tested with the previous version, 43803, that did work fine a couple of weeks ago. Nothing on the PC has changed except for the Win10 updates. The PC uses a Blackmagic Decklink Studio 2K capture and I'm capturing through the SDI connection.

    With the 64bit version, if the device was previously set to decklink, selecting "Capture > Capture AVI..." results in the error and crash. If the device was previously set to anything else, the capture screen opens up and everything is "fine". After getting into the capture screen if you do select the decklink device you get the error and crash.

    With the 32bit version you can always get into the capture screen. You can select the decklink device and the FFV1.3 compression. The problem is that the capture image/window does not show and you get an error when you F5. Error box title is "Capture Error" with the message "unable to start video capture".

    Thanks everyone...especialy Anton.

    I installed the 44331 "patch" and Virtualdub 32bit version works! 64bit version is still broken. But at least I can start digitizing this stack of tapes.

    Thanks!

    After some changes Anton made to my configuration (Thanks!), I was able to enter capture mode with 64bits at least.
    But when I tried to start capturing anything it crashes.

    I tried the following:
    1) I rebooted.
    2) Open Virtualdub2 and enter Capture Mode with Preview and 8ch audio: fine!
    3) I selected FFV1 as videocodec, set a filename (F2) and started capture (F5).
    4) Then it crashed:
    "An integer division by zero occurred in module Virtualdub64" (<- Message with FFV1)

    I've tried capturing 10bits 4:2:2 to x264, Blackmagic v210, FFV1: All 3 crash immediately.
    For other codecs like v210, it says something like: The compressor couldn't be initialized, because the formats are not compatible.
    I still cannot save the crash report. It just says something like "Save failed". :(

    Most of the time restarting VDub works to get back to step 1.

    I've also reduced the number of captured channels to 2, just to rule that out.

      Hi Peter,
      I also had the "save failed" error when trying to save the crash report. What solved this is to run VD as admin....the problem is that the crash report is trying to save to your C: drive's OS folders and it does not like this unless you are admin.

      Still running the 32bit version for FFV1 captures. Looking forward to running the 64bit version when the problem gets resolved.

    Just checking in. Has there been any new versions or patches that have fixed the 64bit version of Virtualdub2?
