BugMaster posted a comment on ticket #9
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.
-
Sorry, but I don't under stand what you mean by "The problem is that the video is very dropped" or "the image is sharp but the movements are dropped." . Can you be specific (screenshots or sample) what exactly are your settings and what wrong with output? Preferably also post mediainfo text output for you encoded sample (like this https://pastebin.com/adD6qZRM).
-
Are you sure that x264vfw codec was used at all? "10Gb per minute " sounds like it raw uncompressed video without any codec i.e. x264vfw wasn't used at all. Check your output video in mediainfo and if it is not H.264 video than something is wrong with how you used x264vfw in you app (i.e. it wasn't choosed).
-
Hi. There is no real video output during "Multipass - 1st pass"/ "Multipass - 1st pass (fast)" as like you used --no-output option. That is why you didn't get x264vfw.avi file (or would get empty/dummy output if you have used VFW output mode). 1st pass is only used to create stats files (x264.stats/x264.stats.mbtree) so encode output is discarded. After encoding "Multipass - Nth pass" you will get resulting x264vfw.avi, no need to change file name between passes (but you can if you want). If you...
-
Hi. It is due to hardware resources i.e. not enough CPU to simultaneously play game and make encoding in realtime. You should find the slowest "Preset" which would be still fast enough for your CPU i.e. probably something around "Veryfast" or "Faster". Also you should set "Zero Latency" tuning if you output in VFW mode in anything else than VirtualDub. And imho "Fast Decode" is not needed for you as you should optimize encoding here and not decoding.
-
Hi. That probably was changed in this commit of x264. Not showing of LZCNT and BMI2 together now is normal. But probably due use of XP (where AVX is not supported) it now detects BMI2 but don't show it also without AVX while already have hidden LZCNT. IMHO it should show LZCNT without BMI2 in your case.
-
I can't control what video info show (except really changing bitrate which it do) or how Sony Vegas mux output file. Do filesize correctly change when you change bitrate in x264vfw or filesize also always the same? Also your bitrate looks like uncompressed video bitrate. Are you sure Sony Vegas really use x264vfw during output?
