https://web.archive.org/web/20120709085619/http://doom10.org/index.php?topic=2135.0 In short {D76E2820-1563-11CF-AC98-00AA004C0FA9} AVI Compressor interface doesn't exist in 64-bit version of qcap.dll so only DMO filters are available and not VFW. It only shows DMOs registred in HKEY_CLASSES_ROOT\CLSID\{33D9A760-90C8-11D0-BD43-00A0C911CE86}\Instance\ 64-bit VFW codecs are only available in VFW supporting apps like VirtualDub64 not in DirectShow.

No. The previous information should be enough if they really want to fix a bug in their product. I doubt that the place in the x264vfw code (codec.c:1881) where the memory access violation occurs will be useful to them.

Hi. I tried to export using Adobe Media Encoder and it failed. This is Adobe's bug: they send a broken memory pointer (icf) in the ICM_COMPRESS_FRAMES_INFO message and therefore the codec crashes due to memory access violation. Ignoring this message is a bad idea because it signals the frame rate and therefore if you ignore it, all bitrates will be incorrect (as if it is always 25 fps). I also tried exporting to Xvid but it fails for the same reason.

What do you mean no longer supported? I tested Adobe Premiere Pro 2023 (23.6) and Adobe Media Encoder 2023 (23.6), both still support x264vfw codec selection when using the AVI output format. Have you installed the full version of the codec, both 32-bit and 64-bit?

x264vfw even says in its name that it is a VfW (Video for Windows) codec, not DirectShow. in GraphStudioNext it is visible in Video Compressors as ACM/ICM type with category "DMO Video Encoder" and category GUID={33D9A760-90C8-11D0-BD43-00A0C911CE86} make sure that your application has the same bit depth as the installed x264vfw, or install the full version (both 32-bit and 64-bit).

If by "dropped" you mean that capture side starts capture in 5 fps instead of 30 fps because your CPU is not fast enough to capture and encode simultaneously than x264vfw can't do anything about this (it encodes every frame it gets but can't encode something it doesn't get because it wasn't captured) and all you can do is to choose faster preset which will need less CPU to encode.
