XMedia Recode problem: No audio !

[penang]

Hello again !

I am experimenting with the latest version of XMedia Recode to lower the bitrate of an AVI file, while also convert the AVI file to MPEG.

The end resulting the MPEG file has no audio !

The first time VCDeasy told me that the MPEG file has no audio I thought it was me who made the boo-boo. So I tried it the second time, and made sure that the audio part (video+audio and audio track 1 and 2) are all in proper order, but ...

... end result for a second run, still no audio !

Can anyone please tell me what I have done wrong?

Thank you !

Post a mediainfo text view of the mpg file you created.

Make sure Video and audio Output option is selected and specify ac3 or mp3 audio, The first page is what you want your output formats to be.

Post a mediainfo text view of the mpg file you created.

First of all, thank you for your reply.

Second of all, thank you for pointing out to me the "Mediainfo" utility.

Below please find the information of 3 files.

File 1 is the original AVI file I ripped from a DVD.

File 2 is the Mpeg file I produced via X-Media Re-code.

File 3 is the AVI file I produced via X-Media Re-code.

Regarding file 2, VCDeasy rejected it, while giving me the following error message:

""Filename.MPEG" analyse failed:

VCDEasy only accepts/analyzes multiplexed program streams.

If this file is a working MPEG file,
check first that it is not an elementary video or elementary audio stream only,
as a multiplexed program stream (video AND audio, or MPEG still) is required."


After that I used XMedia Recode to do an "AVI2AVI" recoding, trying to reduce the bitrate.

And File 3 was rejected by TMPGEnc 2.5, saying that it (File 3) is invalid.

Here are the info ---

More info on File 2 and File 3.

I saved File 2 (an MPEG file) using the MPEG1 format. I set the video bitrate to 600

I saved FIle 3 (an AVI file), video using the MPEG1 encoding and audio using MP3. I set the video bitrate to 600.

If you are trying to create a VCD then audio should be MP2 (mpeg-1 layer 2) @ 224 kbps, not MP3. We What is VCD for the specs.

[penang]

For File 2, the MPEG file, the audio was saved (on Audio Track 1) using the MP2 format. Audio Track 2 I left it blank.

And when I tried to import the MPEG file (File 2) into VCDEasy to convert it to a .bin file, VCDEasy rejected it.

Later on I used Nero to force burn the MPEG file onto a CD-R, and when I played that CD-R on a DVD player, I can see the image but there is no audio.

That was why, before I got the mediainfo utility, I thought that the MPEG file has no audio.

But looking at the output of mediainfo, I can see that the MPEG file DOES come with audio.

And this is the part I do not understand.

Why it has the MP2 format audio but still there is no sound?

[guns1inger]

Your files do not meet VCD specification. Again, read What is VCD and create in spec files. If you work out spec, expect problems.

[penang]

Make sure Video and audio Output option is selected and specify ac3 or mp3 audio, The first page is what you want your output formats to be.

Sir,

Referring to the attached picture, the setting for the "Format" was MPEG-2.

I'm a newbie so please permit me to ask the following questions:

Can I use the MPEG-2 encoding for a VCD?

Or should I the MPEG-1 format instead, for VCD?

Thank you !

The tools such as media info can only report if audio is found, type, bitrate, length ... not if it actually includes anything ... it could be a null audio stream.

Q: What players on the system has the original file been played back in that produces audible audio ?

Why it has the MP2 format audio

Visit on the left "what is > VCD" ... only MP2 audio supported being "MPEG-1 Layer2" ... and this ... Video Cd wikipedia ... Its the standard which was developed.

I thank you for the link to the VCD specs.

I was trying to do something akin to kvcd

Many thanks for the valuable links !!

As for the players on the system that the original file has, which produces audible audio, hmm... good question, because I don't know.

I produced that original AVI file by ripping a DVD. The AVI file can be played on the PC with no problem, video and audio all function as expected.

It's when I tried to cut down on the video bitrate to 600 or so (to produce an MPEG-1 file small enough to be included in a VCD) that things gone haywired.

Before I use the X-Media Re-Code I went to the KVCD site and downloaded the KVCD template and used TMPGEnc 2.5 to convert the original AVI file into a KVCD-compliant MPEG file.

VCDEasy accepted that KVCD-compliant MPEG file with no problem. Produced a bin file for me which I burn into a KVCD.

That KVCD disk does play on DVD players (I tried it on 6 different DVD players, all work) but the video was no satisfactory.

That is why when I was introduced to X-Media Re-Code I carried out all subsequent experiments with it, instead of TMPGEnc and the KVCD templates.

As I said, I am a newbie, so there bound to be things that I would messed up, - and I have, apparently !

[dylz]

Yes you are right, I thought you said output was gonna be mpeg so I figured no-one creates vcd anymore as it's an outddated format but i'm apparently wrong.

How it is: mpeg1 for vcd and mpeg2 for dvd. You can also use avidemux for mpeg1 creation as shown below:

I experienced the same problem, immediately after updating XMedia Recode to v3.0.8.4. I've updated this great app many times and use the same settings. I must conclude that the latest version has a serious bug: it does not support ANY audio format.

I don't like the spyware that is now a part of SUPER, so I downloaded the latest version of MediaCoder (has a messy GUI) and flawlessly converted the AVI on which I was working. No question that XMedia Recode v3.0.8.4 was prematurely released. Sebastian is inaccessible, so we can't notify him of the bug. Maybe his next update will remedy the problem.
