Hi,
I am in the same case like you.
Me, I have done a test with a file recording with my smartphone Android
Nexus One.
It is a format .3gp, a video file in h264 and the audio in amr (aac ?). Is
it the same thing ? Me too, I 'd like to keep the initial format i.e just
stabilize and transform the file, and this operation will be done for any
king of format.
There is some format limitation ?
How have you do this operation (if you have had the same problem) ? If not
how to stabilze/transform this kind of file ? (and some others after ......)
Here, the terminal output about this file and the error that I have in the
first past of the filter (stabilize) :

I must precise that I am using the last version of transcode (i.e 115 and
the filters which come with) installed by the official repository
(multivers, I am thinking), I am on a Ubuntu Natty 11.04 in 64 bits.
Any help is welcome too. :)
By advance Thanks for the help.
Best regards.
