Cannot open H264 video using VirtualDub | ||

| Hi,
I have avi file encoded using H264. I try to open using VirtualDub for processing. An error message "Could not locate decompressor for format 'H264'" is displayed. I have install H264 codec and ffdshow to my computer. Has any one known this problem? Please help. Kinlun Yu | ||

| Try installing quicktime alternative. You might also use the latest g-spot or similar to confirm that it is what you think it is. | ||

| From the error it is definatly an avi with the fourCC H264. Really no need to check and qt alt won't help.
What exactly is "H264 codec"? If you mean x264; it isn't a codec, it is an encoder only. In ffdshow, go into the VfW decoder config and enable H.264 decoding (set from disabled to libavcodec). | ||

| There is more message that I don't show on my previous post. "VirtualDub requires a video for Windows (VFW) compatible codec to decompress video. DirectShow codec, such as those used by Windows Player, are not suitable."
I just install quicktime alternative to my computer and open my video with VirtualDub, The problem does not be solved. Also, I run ffdshow and go into the VfW decoder config, I saw the H.264 is enabled (show as "libavCodec"). Is my H.264 decoder is not for VFW? If yes, do I need install H.264 decoder for VFW? Thanks Kinlun YU | ||

| this sounds similar to a problem i had not that long ago, basically, it means that the video was encoded in a manner that virtualdub cant understand, you can use a differant program to convert it such as super...basically how i now understand it, is there's two differant forms of x.264, one that is compatable with virtualdub and one that isnt........for all practical purposes, the one that is compatable with virtualdub is generally a little bit outdated, so a lot of people use the other version instead.... | ||

| celtic_druid,
Yes, I have setup the H.264 just like screen that you attached in your post. Is there any problem in the setup? Kinlun Yu | ||

| You accessed the settings via the "VFW codec configuration" short cut or from the codec selction in VDub? If from the short cut, make sure that ffdshow actually shows up on the list. | ||

How do you edit 'from the codec section in vdub'? Thanks |
