I have VirtualDub 1.6.19 and have installed ffdshow. In both VFW configuration and Video decoder, H.264 is shown as libavcodec. Yet when I try to open a video that was encoded in the H.264 format, VirtualDub says "cannot detect type of file [....\filename.mp4]." All I am trying to do is advance the audio to sync it to the video, but neither VirtualDub nor AVI_Mux will open the video. Is there a method to use that will cause these excellent freeware programs to sync the audio (AAC) to the video?

MP4s are not AVIs. I'm afraid you will have to look for another tool.

Or use latest VirtualDub with QuickTime input plugin.
Or Avisynth script > VirtualDub.
(A/V recompression required)

Or alternatively - Avidemux (can open MP4 and save to MP4).

Or maybe ... Yamb (MP4Box).
Can change media delay in track properties.

Dear All,

I really don't know what happen. I managed to load in mp4 from Sanyo HD1000 into virtualdub 1.78 i.e., 720p and 1090i files. It was really good.

All I did was to install the k Lite mega pack and make sure that the x264 and h264 codecs are ticked in the configuration page for ffdshow.

hope you can too.
