Problem with 3gp format in Mobile Media Converter

[Bygepp]

Hi.
I've a problem with Mobile Media Converter, I've downloaded the tar.gz package from the official site, I extracted it and runned the application mmc. It works with all formats except the 3gp. Whit this format, appears an error: Conversion failed.
Why the 3gp conversion doesn't work? The problem is solvable?
Thanks.

Maybe you can try via http://www.miksoft.net/momeco.php ?
Also you completely miss important information, like which file (video codec/audio codec) you want to convert.

In this page there isn't the 3gp format.

[doktor5000]

OK, but which format does the file you want to convert have?

EDIT: Ahh, now i see what the problem is - if you click on "More" if you get that error message, you can see the following:

So probably you need to get an older version of MMC, which works with the version of ffmpeg we have in Mageia.
For example http://www.miksoft.net/products/mmc-old ... 161.tar.gz works, just checked.

For example http://www.miksoft.net/products/mmc-old ... 161.tar.gz works, just checked.

Thanks for the answer.
I've tried this version of MMC, but also whit this version the conversion fails. It may be a problem only with my pc.

[doktor5000]

Can you please post the detailed output from MMC for the older version?

And please don't use fullquotes, just reply directly, it disturbs the reading flow and wastes space.

[Bygepp]

Oh, sorry!
MMC gives me the error: Conversion Failed: 1
Thanks.

[doktor5000]

There's a "more" button next to that, which reveals more detailed output, please post that here.
Maybe a problem with the video you want to convert, as it works fine here?

[Bygepp]

Here's it:

This is the 1.6.1 MMC version.
The libfaac.so.0 library is present in the "lib" folder, so, I don't know the reason of the problem.
Thanks.

[doktor5000]

How do you start MMC?
Converting .flv files also works here without problems, must be some problem with your installation or usage.

[Bygepp]

I go to the extracted folder→lib→mmc (executable) and the program starts.
Thanks.

[doktor5000]

Uhmm, no - you should be in MobileMediaConverter folder and run MobileMediaConverter script.

[Bygepp]

I do it, but the problem persists.
Thanks.

[doktor5000]

I've tried again, making sure it's really a video with AAC audio which i'm converting, but it runs just fine. I've also asked some other contributor (thanks, JohnR ) to validate that MMC is working fine. Sorry, i'm out of ideas here ...

The only thing you could do is try to redownload the file you want to convert, it could be minimally damaged, that would be enough to break on such a conversion. I'm assuming you have watched that file already with some media player and can confirm it's working flawlessly from start to end?

I've tried to convert other videos, but in 3gp the error is always present.
Thanks.

[doktor5000]

Looking again at the output of MMC you posted earlier, could you please copy&paste how you start MMC in a terminal and exactly what steps are you doing to convert a video?

[zugunder]

Hi,
As I have exactly the same problem as the topic starter has, I will reply.
I downloaded MMC 1.6.1 and extracted everything to /home/user/Temp/mmc folder.
To run MMC I used:

Code: Select all

$ /home/grigory/Temp/mmc/lib/mmc

It said it was unable to start canberra-gtk plugin, but it started itself. So I closed it, installed 32-bit libcanberra0 and libcanberra-gtk and launched the MMC again.
In the window I selected an AVI file from /home/videos and tried to convert it into .3gp with low quality settings to the same location (/home/videos).
It failed with the same output:

Code: Select all

>> Command executed:
"/home/user/Temp/mmc/lib/ffmpeg" -y -i "/home/user/Videos/123.avi" -f 3gp -vcodec h263 -s qcif -r 15 -b 40k -acodec libfaac -ac 2 -ar 32000 -ab 64k -map_meta_data "/home/user/Videos/123.3gp":"/home/user/Videos/123.avi" "/home/user/Videos/123.3gp"

>> Result:
/home/user/Temp/mmc/lib/ffmpeg: error while loading shared libraries: libfaac.so.0: cannot open shared object file: No such file or directory

I had a 64bit Mageia1 with only 64bit faac and lib64faac0 1.28 installed (from a BDK repository).

After that I installed a 32bit version of libfaac0 from BDK - and after that the conversion worked fine.
I do not know how exactly it happens, but it looks like MMC searches for a sytem-wide faac and tries to use it (which fails in case of 64bit version, but works out for a 32bits). I have not tried to remove faac completely to see if MMC is capable of using its own embedded library (I guess it has it).

So, to put it briefly, you need a 32bit libfaac0 installed.

P.S. The latest version of MMC just does not start on my system.

No you don't need any faac on your system at all, it works fine here without it, on x86_64 and i586. Maybe you also just started it the wrong way.

As far as I can see, it requires preloading of its libs at start, as specified in its launching script, called "MobileMediaConverter".

If I start it just as running mmc executable, it is OK, but it requires external 32bit faac.
If I start it from terminal via MobileMediaConverter script, it runs and does not requite external libraries.
When I put into the App Launcher Menu as "opt/MMC/lib/mmc" it starts fine, but requires 32bit faac.
But I failed to start it via App Launcher Menu when I place there "opt/MMC/MobileMediaConverter".
What should I do? Should I add anything to the PATH?
Thank you.

[doktor5000]

If I start it from terminal via MobileMediaConverter script, it runs and does not requite external libraries.

So why don't you run it the same way from the desktop shortcut?
I've just tried under KDE and

Code: Select all

sh /path/to/where/you/put/MobileMediaConverter/MobileMediaConverter

and you also need to define /path/to/where/you/put/MobileMediaConverter/ as working folder.

Thank you doctor, now it works. I just did not know how to launch shell scripts from the Application Launcher Menu. Now I know.

OFFTOP. I took a look at the first page of the Basic Support page of the forum - you are really everywhere Thanks a lot for your help!

P.S. I can't say for the topic starter, but it seems to me that the issue is completely RESOLVED.

Well it would probably be better if there would be more supporters, f.ex. when i was at Linuxtag last thursday to saturday,
nearly nobody answered all the new threads about Mageia 2 issues, in the last three days i think i did like ~150 replies or so.
That's what we call something like a single point of failure in IT ...
