WinAVI Converter : No Usable Audio Stream

[exec_86]

I wanted to convert some rmvb files into mpeg files so that I can burn them into VCDs. However, when I used WinAVI Converter to convert them, I was prompted with this :

"No Usable Audio Stream, which may lead the converter to be unable work exactly?"

Then I ignored the error and started with the conversion only to find out eventually that my output in the form of mpeg produce no sound at all while my rmvb files do produce sound.

How should I fix the problem?

Thanks.

I'd try a better program. SUPER is free. Try it and see if it does a better job. If you still get the same audio problems, then it's likely your audio is out of spec.

[guns1inger]

Ditch WinAVI. SUPER is one alternative, doing it with seperate tools is the better alternative.

If you check the file with g-spot, what does it say ?
If you load the avi into virtualdubmod, what does it say ?

[celtic_druid]

GSpot and VDubMod don't support rmvb files.

[guns1inger]

missed that bit - way to late to be up

[exec_86]

I tried SUPER after viewing your postings but, unfortunately, SUPER doesn't tend to support rmvb files. I've tried several rmvb files but it didn't work out. When I tried it with a rm file, it worked.

So, do you guys have other alternative convertor or anyway to fix my problem?

Thanks.

EO video can do it. 30 day free trial

[exec_86]

I tried EO Video also. Even worse, EO Video just stuck there and does not convert at all.

How about an AVISynth script using DirectShowSource, then open the AVS file in TMPGEnc and create your MPG-1 file for VCD.

Your AVISynth script would look something like:

DirectShowSource("c:\filename.rmvb")
LanczosResize(352 ,240)
ConvertToRGB()

It sounds like you have a corrupt file if nothing reads or handles it properly

[celtic_druid]

SUPER uses mencoder for rmvb conversion? If so for rmvb files it would need an external dll for RV9/EHQ decoding where as for older rm files libavcodec would be enough.

[exec_86]

Where can I get the dll anyway? And, is there any way by which I can record the sound of my rmvb movies, then convert the rmvb into 'soundless' mpeg, and finally insert the sound into the mpeg? Sound confusing, right? Anyway, thanks for all your golden advice.

[celtic_druid]

mplayer can decode rmvb audio to wav. You can get the real dll's from the mplayer site. Not sure how many are needed these days since cook audio decoding was added to libavcodec. Guess ffmpeg would work for most rm/rmvb files since it now supports cook decoding as well as aac and AC3. Not sure what other audio rmvb files can use other than ATRAC3.

tool=WinAVI_Video_Converter]WinAVI[/url] Converter to convert them, I was prompted with this :

"No Usable Audio Stream, which may lead the converter to be unable work exactly?"

1): Please make sure that Windows Media Player can play the source file. If it cannot, you should refer to http://www.videohelp.com to find more details on how to correct the problem. As long as the file can be played by the WMP, WinAVI can convert it.
2): Please install a k-lite codec package from
http://www.free-codecs.com/download/K_Lite_Codec_Pack.htm (or Klcodec 227f pack or something similar) to your system.
3): Also, the application cannot load any file named with or path that includes any unusual characters. Please check if your file includes some non-english characters and simply rename the file or path. Then it should work.

[guns1inger]

Ignore this poster. Never install codec packs. They bring chaos and pain.

Try installing real alternative to see if you can load it. Otherwise, contact WinAVI support and take it up with them. Maybe it will stop them spamming our happy home.

[celtic_druid]

Don't install codec packs, but do install real alt? Basically that is just a pack and it isn't even strickly speaking legal since it breaches real's licence terms.

It is true though that if dshow players can't playback the audio, then winavi, etc. aren't going to be able to convert it. With newer rmvb files there is a decent chance that they use aac audio, so installing coreaac could help. So really the starting point as always should really be to see exactly what you are dealing with rather than installing random stuff and hoping for the best.

Load the file in MediaInfo and see what audio it uses.

sorta in the same line of question... I can convert with WinAVI but the rmvb has two languages mandarin/cantonese. How can I only encode cantonese and take away mandarin? if that's possible.

thx

[celtic_druid]

Two streams or just left/right? Don't think rmvb supports multiple internal streams. Requires the use of scripting.

[exec_86]

Thank you guys!!! Problem Solved!!! Yay!!!

[stinkytofu]

so there is no way for me to exclude one audio when converting to dvd or divx?

[celtic_druid]

Of course there is. You never answered my question of whether it was a matter of left/right being different languages or two streams.

[stinkytofu]

oh sorry, its the left/right. Thanks

[celtic_druid]

Well, I guess it depends how you are converting. For instance if you are using AVISynth to frameserve then you can use getchannel(1/2) to select a channel, etc. As with most things I'm sure there are numerous ways you could go.

[stinkytofu]

can you give me a step by step instructions? the only thing I've been using to convert rvmb is WinAVI.

thx

Will give you the fundamentals of using avisynth to extract video or audio from rmvb files. Once you have your avs script loaded into virtualdub you can save the audio out as a wav file, load it into an audio editor, and copy the language you want (right or left channel) over the one you don't (the other channel). Save is again, and use this in place of the original audio when you encode for DVD or avi.

[stinkytofu]

thanks I'll give it a try.

[celtic_druid]

You can actually do basically all of that in AVISynth:

video = directshowsource("whatever.rm",fps=25)
mono = GetChannel(video, 1)
stereo = MergeChannels(mono,mono)
return AudioDub(video, stereo)

or something like that.
