no audio with 3gp video files

[Nicola Jelmorini]

I have just installed OpenShot 1.3.0 on my Ubuntu 10.04 64bit system.
When I import a file in 3gp format, no audio is reproduced.
The video file is created with my Android phone: the video track is MPEG-4, and the audio track is "AMR mono"

When I watch the same file with the Totem player (Gstreamer based), the audio works correctly.
When I watch the same file with the VLC player, this error message is displayed "VLC don't support the audio format or video "samr". Like Openshot I can see the video track, but no audio.

Hi,
I have too an android phone and I have none problems with. You must have the version of ffmpeg who is in the Medibuntu repository only the one who provides the 3gp support. See here : https://answers.launchpad.net/openshot/+faq/1040 and in the same occasion you should check all your dependencies see here : http://openshotusers.com/forum/viewtopic.php?f=12&t=758

If you are having trouble with a video or audio codec, please read the following FAQ:
https://answers.launchpad.net/openshot/+faq/983. Once you provide all the debug information needed, we can update the ticket status back to 'confirmed' or 'invalid', depending on what you find. Thanks!

[Nicola Jelmorini (jelmorini)]

Ok, I have uploaded one video 3gp file to reproduce the issue.
The filename is "VIDEO0007.3gp"

[Olivier Girard (eolinwen)]

Have you check all the answer that you have received ? If you don't use the medibuntu version of FFmpeg, you will never work with this format.
To my side, I am going to look this file.

[Olivier Girard (eolinwen)]

I have none problem with. Hum Spanish or Italian ?
You don't use the version of Medibuntu. See the link of the faq n°1040 for resolve that.

[Nicola Jelmorini (jelmorini)]

Sorry for the late answer, but now it's ok. Following the hints in the FAQ all works well.
Thank you, this bug report can be closed for me.
