Dear Francesco,

The video indeed has good quality on other handsets (also the audio, which is good in both cases - N95 and N80).
I attached an mp4 file for you. I used the following to generate it with ffmpeg:
ffmpeg -y -i intro.avi -ab 12.2k -ac 1 -acodec amr_nb -ar 8000 -vcodec h263 -r 10 -s qcif -b 44K -pass 1 -passlogfile log /usr/videodemo/intro.mp4
ffmpeg -y -i intro.avi -ab 12.2k -ac 1 -acodec amr_nb -ar 8000 -vcodec h263 -r 10 -s qcif -b 44K -pass 2 -passlogfile log /usr/videodemo/intro.mp4

Ciao,
Rene

Hi,

I gave a look to H223 dumps.
N95 sends again and again an indication never seen before on other
handysets. And for sure libh324m doesn't do nothing when receives it.

At a first sight it seems to me that it is complaining about too slow
frame rate...

If you confirm me that the same video has good quality on other
handysets, I think this is the starting point for investigation.

Anyway...could you send an  mp4 file you are using?


Greetings
Francesco
