recently ,when i use winavi to convert some rmvb file to mpeg file ,it still shows no sound but i use allok rm to dvd converter,it's ok.it seems so strange,who can tell me why?

Sorry, but i really don't understand this, I've made a post about AVISynth a few months back, and still no one had tried it?

Using avisynth to frameserve video files to most encoders would solve all kinds of problems. I'd just tried and confirmed that Winavi does support avs scripts.

When an video file is played but no sound coming out, it could be the system that couldn't locate an audio decoder for that particular codec. Even though you may have the necessary codec installed.

You can try this:

Download the latest built of FFDShow http://www.free-codecs.com/FFDShow_download.htm

Install it and will overwrite any existing older version. After installed, go to ' Start -> All programs -> ffdshow -> Audio decoder configuration -> (enable LPCM, and choose 'all supported' on Uncompress Formats)


To show the choices, click once on the item selected.


Then click 'Apply' and 'OK'.

hi ,agelessoldman ,do you mean that i need to download " FFDShow MPEG-4 -video decoder"  & i don't see "FFDShow audio decoder" or avisynth,can you help?

Yes, download FFDShow mpeg-4 decoder. It seems like a codec pack, but its not.

For AVISynth download and a somewhat simple instruction, go check the ConvertxToDVD guide post.

do i need to install all components & it also contain avisynth,so do i still need to check the convertx to dvd,thanks

I believe the avisynth mentioned when installing FFDShow is meant to apply all the settings when frameserving avs scripts. FFDShow itself do not include AVISynth. You have to download and install it separately.

Here, download either versions, it should be fine.

By the way, I told you to check the ConvertxToDVD post because at the bottom of the post, I've written a simple instruction of using avisynth.

after i check into convertxtodvd post,i didn't find anything about avisynth,why? do the address is www.codecs.com/download/convertxtodvd.htm

AVISynth:
