Converting .MP4 to .RM Help (Video works, Audio doesn't) Offering $5

[felguard]

Okay, so I'm using WinAVI to convert a .mp4 video file to a .rm file. As you may know, this doesn't work because WinAVI won't recognize the file.

So in order for the conversion to work, I used AviSynth:

DirectShowSource("[Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4")

I open WinAVI, and selected the file with the above code and converted it to a .RM file. The conversion works and I can see video working fine, but there's absolutely no audio.

Can someone help me solve this problem?

May someone please help me solve this? I'll offer you 5USD via paypal if you want.

I was told to:

Extract with YAMB and convert with BeLight.

Download YAMB

http://yamb.unite-video.com/Yamb-1.6.exe

The above program should allow you to demux your audio from the video

or

Convert the audio to WAV with ffmpeg.exe http://ffdshow.faireal.net/mirror/ffmpeg/

ffmpeg.exe -i "[Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4" -vn -y audio.wav



video=DirectShowSource("[Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4")
audio=Wavsource("audio.wav")
convertAudiotofloat()
normalize()
return audiodub(audio,video)


The unknown part - I dunno what format your audio is in - AAC perhaps ? ffmpeg should convert directly to wav.

Thank you for the reply, do you know if there's a guide somewhere on how to use YAMB?

And also, what do I do with the ffmpeg?

Sorry, as I'm only a beginner for these things.

I doubt you'll need YAMB, now that I think about it.


Download this app to make your life easier -

http://www.roggel.com/cgi-bin/DLCounter/load.cgi?NGNeer/BackgroundCMD/BC_Setup.exe

Once you've installed it, go to the folder where your mp4 file is located. RIGHT CLICK anywhere in that folder and you'll see a choice called "CMD Prompt".




That should give you something that looks like:

C:\>

make sure ffmpeg.exe is in the SAME folder as [Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4

so, you'd type in:

C:\>ffmpeg.exe -i "[Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4" -vn -y audio.wav

Press ENTER to execute the above command.


That will/should give you a standard WAV audio file called AUDIO.WAV


Look at the modified AVisynth script in my first post to see how to incorporate AUDIO.WAV into the script.

Oh ok thanks. Where do I put the ffmpeg.exe in?

I get this message like "The application has failed to start because of pcgthread or something."

Same folder as your MP4









BTW - If it all works and you get a RealMedia file with sound, donate the $5 to videohelp.com

I have the same problem as these do:
https://forum.videohelp.com/viewtopic.php?p=1459509#1459509
https://forum.videohelp.com/viewtopic.php?p=1502653#1502653

And they were answered with:

extract with yamb and convert with belight.

Would that way be easier?

P.S. I edited my above post with the error message I get after typing the command in.

Gladly man, it's the least I can do.

[Soopafresh]

OK, no problemo

Put it in the same folder as ffmpeg.exe

[Soopafresh]

felguard - yeah, that'll be plan B if it doesn't work. BTW, I have to step out for a bit, so folks, if you'd be so kind the help the guy out in case of no workeee.... I'll check this post in an hour or so.

[felguard]

Okay, thanks.

I've got the audio file seperated, but when I insert the following to the AviSynth code with WinAVI to convert...

video=DirectShowSource("[Saizen]_Eyeshield_21_-_54_[DVD][FD881893].mp4")
audio=Wavsource("audio.wav")
convertAudiotofloat()
normalize()
return audiodub(audio,video)

The output comes out to a 298kb file that gets an error.

[felguard]

I got the audio file separated, but where do I go from now?

[felguard]

May someone please help?

Nevermind, got the problem solved. Thanks for the help. I will donate $5 to videohelp as you request, thanks again.
