3GP splitter

[vlada]

Hello,
a friend of mine asked me to help him with playback of 3GP files. I tried them on my computer and they play normally (H263+AMR - FFDShow decoder). I believe the problem is in 3GP splitter.
From the informations I read on this forum, 3GP should be a modification of MP4 and both Haali Media Splitter and 3ivX splitter should support it. I told my friedn to install these splitters but he said that some movies still don't play.
I'm trying to find out which splitter is used on my somputer. IIRC I only have Haali Media Splitter (AKA MatroskaSplitter) installed. This splitter usually shows a tray icon, but I have no tray icon when playing the problematic 3gp file. Also if I check which filters are used while playing in MPC/BSP/ViPlay etc., there is no splitter listed. Graphedit and GSpot didn't help either. How can I found out which splitter is used on my computer a which one should my friend install to make it work?

Thank you,
Vlada

Open your file with graphedit...You can see which filters are used for playback.

[vlada]

No I can not. Of course I tried this. There is no splitter listed. There is only source filter and from there it splits into audio and video stream.
I can send you a screenshot afternoon when I come home.

Technically Haali's filter is not a splitter, its a source filter and splitter in one. Just right click on the filter and see if you can get in the properties.

Attached you'll see a part of my graph. GraphEdit says that the source filter has no properties. But I made the same movie work on my other computer with MatroskaSplitter. Strange....

Have you tried renaming the files .mp4 ?
It should do the trick.

@Vlada

maybe your 3gp files have unsupported streams e.g. Q-CELP audio.
Just check them with mp4box or QuickTime.

As a side note - mp4box might create valid .3gp (3GPP/3GPP2) files but not 100% "compatible" QuickTime 3gps -> result: playback problems on mobile devices.

[vlada]

I don't think renaming the files would help, but it's easy to try it, so why not. As I said I have no problems playing the files (MPEG-4/AMR). But a friend of mine can't make them play. I can only give him advices over e-mail. He says it doesen't play even if he installed Haali's Media Splitter and FFDShow. But this works on both my computers. I don't know what else could the problem.

If the tray icon is missing

http://mr-36758.v-mirror.spb.ru/la/forum.ru/Haali.jpg (first icon)

the splitter isnt loaded.


To solve this open up a text editor and enter the following lines:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Media Type\Extensions\.3gp]
"Source Filter"="{55DA30FC-F16B-49FC-BAA5-AE59FC65F82D}"

Save that as e.g. haali-for-3gp.reg and execute the file afterwards.

Of course you could dump directshow and try e.g. mplayer

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Media Type\Extensions\.3gp]
"Source Filter"="{55DA30FC-F16B-49FC-BAA5-AE59FC65F82D}"

Save that as e.g. haali-for-3gp.reg and execute the file afterwards.

Other way - rename *.3gp to *.mp4
